[Pokémon] What is the devastation from which the Rocket Team want to protect the world and to denounce the evils of truth and love? | 18 | Team rocket don't actually want to protect the world. We can see that with it's leader giovanni , when leading team rainbow rocket he leads the joined forces of other villains of the series from other world's where they have won. Each owning a legendary pokemon which caused destruction plus Lysandre's ultimate weapon.... | 19 | |
[General horror] How to pick a Final Girl/Guy | Hi, everybody. How are you all doing?
As a hideously deformed monster who was raised in a root cellar by his possibly insane grandmother, I was thinking I’d spend my summer stalking a random group of generically attractive high school seniors, brutally murdering them one by one in various creative ways – possibly invo... | 114 | It might be hard to spot, but pick The one that has The biggest potential for self growth. That way, you will make them discover their own badassery and will to live, and If you both survive this, it will make The next time you meet that much more intressting, when this battled harden survivor must try and protect The ... | 67 |
The idea of getting a sex change is ridiculous. CMV | Gender isn't a real thing. There are human beings with penises, and human beings with vaginas. The whole idea of boy/girl and man/woman is just a product of gender roles and stereotypes. You can't be a man (person with a penis) and "feel" like a woman simply because you like to shop and play with barbies and wear dress... | 42 | People don't get SRS to conform or to have people view them differently. They get it so they can feel whole. Look the concept of being trans and the dysphoria and discomfort that goes with it is difficult to understand without being trans, but seriously, they do it to feel whole and comfortable with their body. | 36 |
There is a news alert in my city that ozone levels are predicted to be dangerously high this afternoon. How are ozone levels predicted for a particular day and place? | 417 | Almost all ozone near ground level is formed by reactions happening in the atmosphere. The most common pathway is for NOx gasses (NO or NO2), mostly produced by vehicles, to react with volitile organic compounds (VOCs) coming from a variety of sources. That reaction needs energy from sunlight, so a high ozone concentra... | 121 | |
ELI5: How wine is made. | Also, is making champagne much different? | 31 | Yeast is the real secret. It's used in a lot of things, and it loves to eat sugars. When it eats sugar, it poops out alcohol and burps carbon dioxide. Some kinds of yeast make more carbon dioxide and some make more alcohol. The kind in bread makes mostly carbon dioxide and that's what makes bread rise. The kind i... | 19 |
Is a twin born through in vitro fertilization more likely to give birth to twins? | As I understand it, twins are more likely to have more twins. Does this hold true if the twin was a twin because of in vitro? | 53 | In a word, no.
There are two kinds of twins. Identical and fraternal (non-identical).
Identical twins form from one fertilised egg. So two babuea from one egg. We dont know why this happens in most cases, but the chances of it happening are uniform across populations.
Non identical twins are the result of two eggs ... | 41 |
[Star Wars] Why don't more Jedi wear armor in battle? | I mean robes are really stylish, and traditional, but there have been times in the galaxy when the Jedi are forced to go to war. Why don't more of them opt for armor, especially the lightweight variety that does not hinder their movement or agility while providing protection against explosions and blaster fire?
I noti... | 42 | Some did, especially during the Clone Wars, but you gotta remember that Jedi are primarily peacekeepers, and aren't warriors. Their primary purpose when traveling to a conflict is to defuse that situation. Showing up in full battle rattle isn't a great way to convey peaceful intentions (even if it might seem most pract... | 66 |
[Full Metal Alchemist] Can Edward just transmute his body to be bigger or to regrow his body parts? | As I understand the problem with human transmutation is the whole value of a soul problem; but if that's the case you don't need to even touch your soul to grow your legs out a bit or put a new hand on your stump. So why do that instead of the whole automail thing? | 24 | Amestris alchemy science flatly doesn't cover the transmutation of flesh, and research into chimeras is pretty much top-secret military branch of state alchemy.
Maybe if this happened in Xing, where alchemy took a different turn in development, it would be possible to somewhat alleviate the plight of amputees, but Am... | 41 |
ELI5:How southwest airlines is relatively inexpensive and lets bags fly free without bankrupting the company | 33 | Southwest does not have the frills of other airlines. Think peanuts as opposed to meals. Also they do a good job of controlling fuel costs through a hedging program. Basically fuel hedging means that they buy fuel in advance when prices are low. Sometimes they do buy high and get burned when fuel prices drop, but g... | 23 | |
[Comics & Manga] If Spiderman gained the Speed Force, considering his Spider Sense, would he pretty much be untouchable? | Also, how would a Spider Sense + Speed Force combination compare to Mastered Ultra Instinct (DBS), in terms of how untouchable they'd be? | 25 | Assuming speed equalized, Spider-Flash *would* be pretty much untouchable, but he'd still be inferior to MUI in a straight fight. Spider-sense is defensive and focuses on avoiding danger, while MUI is both defense and offense. They'd start off similar when defending, but the MUI user would dodge in ways that gave him... | 22 |
[Dr. Strange/MCU] In this universe do sacred texts from various cultures contain contradictions? | The Ancient One proposes to Dr. Strange that individual methods of understanding the mind, the body, etc., taken from different explanations of reality, are only each of them a single piece to the same puzzle. This is fine, but I want to know if this strategy of thinking forces in-universe characters to overcome contra... | 24 | Of course there are contradictions. There always are.
I like this exchange to explain it:
Strange: That doesn’t make any sense.
The Ancient One: Not everything does. Not everything has to. Your intellect has taken you far in life, but it will take you no further. | 24 |
How do needlers work in the Halo universe? | I thought they exploded once they reached a point higher than a certain mass, but they're kept in the gun in pretty large quantities already, and in Halo Wars there are gigantic turrets that shoot massive ones at aircraft. I'm also pretty confused how they travel at such a low speed while remaining aloft and turning al... | 28 | The projectiles are probably organic. It would explain how they steer and control themselves in flight and how they are able to identify a foe target and detonate when necessary. The crystals could also contain a form of plasma energy that requires several to explode, but has to be "armed" by moving at a high speed. Or... | 17 |
I believe murder is justifiable if there are no possible negative effects on society. CMV | First of all, please note that my argument is purely theoretical, due to the fact that the positives and negatives of any action are never clear. I would never condone murder, simply because it cannot be known if any negative effects are to follow.
That being said, I would like to construct a possible scenario. There ... | 15 | There are two separate threads of logic going on here.
thread 1:
If no one is affected by this person's death then this person doesn't matter
thread 2: This person doesn't matter to themself.
Thread 2 is completely indefensible. People who think like this kill themselves. Therefore for any person who has not yet ... | 15 |
ELI5: If your whole body is hot under the blankets at night, how does sticking one leg out from under the blankets reduce body temperature enough to make you comfortable again? | 592 | One leg has a decent amount of surface area that it can cool down when it's exposed to the cooler air.
If you're wondering why one leg doesn't get cold while the rest of you stays warm, that would be blood flow. The leg and the blood in it cool down, and the cooler blood circulates through your whole body, bringing th... | 489 | |
Why are UHF TV antennas (almost) always loop antennas, vs. VHF antennas which are usually whip antennas? | 179 | The length of an antenna is related to the wavelength of the signal it is meant to receive, typically some fraction (1/2 or 1/4). UHF wavelengths are less than a meter, so loop antennas (antennae?) work fine. VHF wavelengths are longer, 1m - 10m, so they need longer antennas.
There is math involved, so someone else wi... | 56 | |
[General] What universe is the easiest (or most difficult) to start as a low rank and work your way to a commendable rank? | For example, in FMA universe, everyone can learn alchemy but it'd take years of studying to do it. So, if I was an ordinary person, I'd take a few months to years to practice alchemy and get the hang of it, then a few more years to hone my skill. Depending on how difficult it is, I may or may not reach the required ski... | 39 | I'd probably go with the Warhammer 40k universe for hardest. The casualty rate for "guys at the bottom" is so high you'd have a better chance of winning the lottery at the exact second you got struck by lightning than surviving, much less advancing all the way to the top. | 39 |
[ELI5] why do spiders tend to build webs in the same places when they get destroyed every day? | For some more context, I park my car under a pine tree every day. Every morning when I leave for work there's always a couple of spiderwebs going from my car to the tree. Naturally I destroy them. Why do spiders keep insisting on building webs in places when they're consistently being destroyed? | 337 | During the time right before dawn to right after dawn, nocturnal insects head in to sleep, while diurnal insects wake up and head out to do... insect things. Spiders often set their webs to catch this transitioning prey.
After the sun has risen, the spider has gotten all the food he expects to catch from this web, has... | 332 |
ELI5: Prime numbers and encryption. When you take two prime numbers and multiply them together you get a resulting number which is the “public key”. How come we can’t just find all possible prime number combos and their outputs to quickly figure out the inputs for public keys? | 7,899 | The number of all possible prime number combos is simply too large.
Public key encryption relies on asymmetric mathematical operations - operations that take much, much longer to perform in one direction than the other.
Prime factorization is one of those. 12503 and 16187 are both prime numbers. If we multiply them -... | 6,756 | |
Will I generate more power if I focus sunlight with a magnifying glass onto a solar panel? | 111 | If your magnifying glass is bigger than your solar panel you will get more power. The lens would collect over a larger area than what the panel is able to do on its own.
However there is a couple of things to consider. First the solar panels efficiency drops with temperature. So usually a 2m^2 panel would produce more... | 81 | |
[Star Wars] When did the bounty hunter profession get turned into being a hitman/assassin? | Boba Fett in ESB seems to be the correct usage of the bounty hunting profession. He was hired by someone (an actual authority if you want to get technical) to bring in a criminal. He fulfilled his contract, he got paid.
When did this turn into these ideas of Boba Fett icing tons of people, scalping Wookies, disintegra... | 27 | A bounty hunter is really just someone who finds/receives open contracts and tries to fulfill them while working as little as possible. The galaxy's most infamous bounty hunter probably had informant networks in almost every system that would give him lists of the best bounties. That way he could execute multiple bount... | 27 |
ELI5: what makes ankle joints withstand age-related wear and tear, comparatively speaking? | Hip replacement surgeries are commonplace, especially due to age-related damage. But ankle joints don’t seem to suffer the same amount of damage / require replacing as much as either hips (or knees) do, despite being smaller and more delicate constructions. What in the construction of ankles makes them more resilient t... | 22 | The magic of the ankle biomechanics is more-so in the synergy it has with the foot than simply the ankle itself. The ankle-foot complex (AFC) is an extremely intricate & complex structure with a high concentration of bones and muscles, connected by very supportive and flexible Connective Tissue (Tendons, ligaments... | 10 |
[2001: A Space Odyssey] Why wasn't the crew of the Discover briefed about TMA-2? Why brief HAL, but not the crew? | I don't understand. I can see the need for secrecy prior to launching the Discovery mission, but to keep it secret the entire time?
I mean, HAL really didn't need to know about it until they got to Jupiter/Saturn either... or they all could have learned about it. | 15 | They were juat the pilots and didn't need to know about it. The plan was for them to go into hibernation once Jupiter (Saturn in the book) was reached, and for the science team who had been briefed to wake up until it was time to go back. | 10 |
CMV: Laws should be strictly enforced | If there's a law on the books and someone is discovered to be breaking that law, it should be strictly enforced. That doesn't mean a police state where we have cameras everywhere to catch everyone, but it does mean that we shouldn't "de-prioritize" crimes or let people off with a warning.
If a crime is a burden on the... | 40 | I think even well designed legislation will run into hurdles where common sense needs to prevail. For example, it is unlawful in New York City to ride a bicycle on the sidewalk. This makes sense, since NY sidewalks are quite heavily used by pedestrians and bicycles pose very real hazards to pedestrians.
However, it ... | 34 |
CMV: Opinions can be wrong, and wrong opinions should be unacceptable. | In other words, having an opinion does not make that opinion valid. You can be *of the opinion* that a square is not a rectangle; yet, a square is, in fact, a rectangle, whether you think so or not.
Of course, the waters get a little muddier with more complex and controversial issues where reasonable cases can be made... | 26 | No, you cannot be of the "opinion" that a square is not a rectangle, because that is a statement of fact, not subjective opinion. It has an objective answer. In the same way, you cannot be of the "opinion" that 2+2=5. That isn't an opinion. It's just being wrong about something.
On the other hand, saying "drinking and... | 25 |
[Harry Potter] How significant was Lord Voldemort's escapades to the wider wizarding world? | We know that the magical world exists beyond England and Hogwarts. I was wondering how much impact Voldemort had on the wider community?
Did they not 'speak his name' and feared him? Or was it something they read about in the news? | 19 | He was barely know outside of Britain and not much of a threat to outside powers. The big name that everyone feared was Grindelwald that supposedly conquered part of Europe.
Voldemort was just small fry and even thought as a rebel and a hero in other countries for fighting against the stagnating English wizard society... | 15 |
ELI5: Why does concentrating on falling asleep keep you from actually falling asleep? | 221 | If your brain easily fell asleep when focused on a task you'd never succeed at any task related to staying alive and passing on your genes. We've evolved to stay conscious when actively trying to do something, even if that something is to fall asleep

[MCU What If] Why did Killmonger....? Spoilers | Why did Killmonger reactivate the drones? He already defeated them, and he had gained the trust of the Wakandans by deactivating them. What was the point in reactivation them inside the shield? | 48 | Simple. Bringing them the corpse of Klaue and swearing fealty to T'Chaka proved his loyalty. But fighting the drones and saving the queen and the Dora Milaje showed his heroism, thus guaranteeing that he, not Shuri, would become the Black Panther and T'chaka's heir apparent. Killmonger wants to be king so he can bring ... | 88 |
[Star Wars] Why was Tatooine so diverse? | Tatooine seems to be a desolate planet mostly covered with deserts, yet as we saw at Mos Eisly it appears to hold countless races. Did Jabba the Hutt as a crime lord bring in a diverse cast? Or is Tatooine just weirdly diverse? | 22 | Well, you have to remember that Mos Eisley is a spaceport, so you are naturally going to attract a wide variety of individuals from various places. Yes, some of them work for Jabba, but many others were just traveling and were currently stopped at that port. | 43 |
ELI5: Why do we spell the country as 'Philippines' but the language as 'Filipino'? | So why are they spelt differently?
'Filipino' also describes the people, culture, cuisine etc. | 305 | Philippines is an old English name of the country. It was a Spanish colony, the Spanish name for the country is Islas Filipinas. Then the people of the Philippines decided to choose a new language to become the national language. They chose a language called Tagalog. Tagalog called the Philippines the same way as Spahi... | 107 |
Why does hair change as you age? ie in colour, curly to straight... | When I was younger I had straight blond hair. Now I have completely different curly ginger hair with the opposite texture. I have heard of hair going straight to curly, but not so much the other way round. Why is this?

Edit: Front page! Thanks for all your insightful respon... | 2,859 | Part of this is due to the changes in hormonal balance and the length you keep your hair. As you age the hormone levels in your body will change impacting your hair texture and sometimes the color. There are other environmental effect other than length as well. For example, humidity will increase the curl potential of ... | 1,053 |
When did the CMB (Cosmic Microwave Background) pass through the visible light spectrum? If we had been around at that time, would it have been bright enough to see it? | 17 | At its inception it would have been visible. During the early moments of the Universe it was still immensely hot, so hot that the atoms around where always ionized as a plasma. Plasmas are incredibly opaque because with the electrons and nuclei separated they can absorb a wide range of photon energies, whereas when con... | 12 | |
We are Leah Boustan and Ran Abramitzky, economics professors, and authors of *Streets of Gold* a book about immigration to the US, past and present. AMA! | Hi everyone! This is Ran Abramitzky from Stanford and Leah Boustan from Princeton. We are economics professors and economic historians.

[Injustice League] They want to plan an all-out attack against the Justice League. Which hero do they need to plan the most contingencies against in order to have the highest success rate possible? | 24 | Plasticman. You wouldn't think so, but he's immune to telepathy, practically immortal, nigh-indestructible, and completely unpredictable. And that's if you get the *nice* Plasticman.

[Megamind] How did Hal not immediately kill Megamind? | So, Hal was granted with ALL of Metroman's superpowers right? Later on in the movie we see Metroman just casually walk around the entire city Quicksilver style in less than a millisecond. It was established that Metroman could have easily taken out/killed Megamind if he wanted to. What's stopping Hal from doing the sa... | 59 | Could be that he's simply unaware that he can move that fast.
Hal was trained in how to use his powers by Megamind and he only found out that Metroman could move that fast when Metroman told him and Roxy. | 100 |
ELI5: What is torque? | 1,968 | Alright so the easiest way to get the concept of torque is to look at a loooooong pole. This pole has a certain mass and nothing will necessarily change that. However if you hold it at the center you'll notice that it is incredibly easy to balance. Now try to hold that rod at the way end while also trying to keep it ba... | 1,924 | |
[Dragonball Z] If you were in Babidi's position, how would you control Majin Buu (in his fat form)? | It seems that Babidi made major mistakes in controlling Majin Buu by being a insufferable prick to him. How would you avoid making his mistakes, and if you were in his position, how would you get Majin Buu under your control? | 30 | Just be nice to him. Buu is basically a child, with a childlike mentality. It was shown with Hercule that so long as you are just a friend to him he's more than willing to listen to you and curb his more destructive impulses. Babidi's issue with Buu is the same issue he had with anyone; he was a destructive prick who w... | 42 |
[Superman] How would Superman's story play out if he was Black and had landed in the US during the 1930's? | 45 | Probably *pretty* badly.
There was a similar-ish situation in Gods and Monsters (which is a pretty neat animated DC thing) where the superman of that universe, son of Zod, crash-lands and is taken in by an illegal immigrant family. He gets a different taste of Earth and it's people, what with all the living in humilia... | 80 | |
Are hemp plastics structurally distinct from petroleum-based plastics? | A friend the other day tried to tell me that hemp-based plastics are superior because they're biodegradable, but I don't know that I believe that. After all, it is still plastic... right? | 99 | "Plastic" is a term that describes a material that uses polymers as the main component.

However a lot of people fail to point out that the bible is very old and has been translated a million times. Ever translated something a million times using Google Translate.

ELI5: Why do I get motion sickness when I'm in the car not driving but don't get motion sickness when I'm driving? | EDIT: Thanks for the explanation guys. I get motion-sickness very easily and I found driving to be a way to get around that while in the car. | 32 | When you are doing the driving your brain and body know ahead of time what movements be will occurring before they actually happen, like turning, braking, and accelerating.
When you are a passenger, you are kinda like a rag doll being tossed about. | 24 |
If most of neutrinos were created during the big bang and neutrinos move faster than other matter, wouldn't big-bang-neutrinos be too far away to interact with? | Is it: because the universe is not expanding from a center, then big bang neutrinos are coming from all directions, not in an "outward direction" from some center?
Much of my confusion might result from a misunderstanding of the big bang, and assuming neutrinos travel linearly in space. | 70 | >Is it: because the universe is not expanding from a center, then big bang neutrinos are coming from all directions, not in an "outward direction" from some center?
That's it!
The Big Bang happened *everywhere*. It wasn't an explosion from a single central point that we can point to and say, "there it was." | 29 |

CMV: Schools should start at a time that allows them to get out 15-30 minutes after the average worker is done with work | The average high school starts between 7:45am and 8:15am, and releases between 3:00pm and 3:30pm. This is wrong for a lot of reasons, but I think that the focus should be more on the release time than the time that kids get to school. A lot of the articles I've seen that critique the start and dismissal times focus on ... | 727 | >Therefore, it would be better to have school start whenever allows it to get out around 5:15 or 5:30 even, to give parents the ability to get to their kids school for pickup time.

ELI5: Why can’t Drs lubricate or cushion your joints to cure arthritis? | I’ve seen some operations where they replace joints like the hips completely, why not some car tiles he replacement to cure it? | 17 | They can and it is a simple in office procedure that many orthopedic offices do offer. It’s an injection called Joint Fluid Therapy. The problem is that they haven’t found a lubricant that lasts, so the procedure is more of a relief from the pain/ a way to delay the need for a joint replacement. | 23 |
[Bojack Horseman] Where did the "horseshoe" come from? | Horses have hands with fingers and feet with toes just like everyone else. So why are horseshoes made out to be something special, and why are they shaped like some kind of half-ring that would never fit on any horse's foot? | 53 | Horseshoes are for playing Pitch. How else would you play Pitch? They aren't literally shoes for horses that is ridiculous. Horses wear Adidas, Nike, and other typical brands. It's like how foxgloves are flowers, not something foxes wear and crows feet are wrinkles, not literally feet on your face. | 61 |
CMV: the age of adulthood should be the same for all rights and responsibilities, and all restrictions thereof | It is my view that the inconsistency in the way we treat the age of adulthood (for the purposes of administering people's rights and responsibilities) is causing undue harm in society, both due to collateral damage of allowing people too young to engage in risky activities, and due to the pervasive acceptance of blatan... | 1,030 | Why is consistency an inherent good? Sure cars are dangerous but that's hardly enough similarity to say they must be treated the same as guns, just because guns are also dangerous. These things should be treated differently because they are different. | 307 |
ELI5: What makes cleaning/sanitizing alcohol different from drinking alcohol? When distilleries switch from making vodka to making sanitizer, what are doing differently? | 12,019 | CAUTION: Ethanol that is sold for cleaning has been denatured, i.e. made poisonous to drink. It is pretty close to impossible to purify denatured alcohol to make it safe for drinking. Isopropanol (rubbing alcohol) is also sometimes used for cleaning, but it is also toxic. Ethanol for drinking has been distilled or ferm... | 6,642 | |
CMV: People should not be able to purchase soda with SNAP benefits | The idea of SNAP is to supplement nutrition, but soda has no nutritional value. A candy bar would at least offer satiation for a short period of time, soda won't even do that. Soda barely, if at all, can even be defined as a food. Google definition for food: \*" any nutritious substance that people or animals eat or dr... | 31 | The problem is with how items are restricted/categorized by the government.

[Marvel Universe] Why isn't the Purple Man (Zebediah Killgrave) one of the most powerful villains in the world? | Killgrave has the ability to control most people through his pheromones. Basically, people are obligated to do anything he asks, as long as he's physically near them. He could easily talk his way into the upper ranks of every government and superhero allegiance in the world. So why doesn't he? | 91 | Because he is in fact literally a purple man who needs to be present for his powers to work. He's easy to spot and his powers are defeated by anyone with an oxygen mask. His influence wears of pretty quickly once he leaves.
All in all it means he's pretty easily defeated when people realize what he's doing, which is h... | 115 |

Golems must be created and are commonly done by either ancient druidic cultures to protect an area or by accide... | 37 |
ELI5 How do the medicines like paracetamol or ibuprofen work? Do they help the brain by making it ignore the pain (suppressing) or by actually fighting the cause of pain? | 38 | Ibuprofen works by stopping an enzyme from creating chemicals called prostaglandins that can cause pain and inflammation.

[Death Note] Can the death note kill people with diseases that take a long time? | If there's a limit of about 20 days before the death note gets bored and defaults to heart attack does that mean that it's impossible to use illnesses that normally take longer? For example let's say that a 20 year old man's name is written in the death note and the cause of death is specified as dementia. Does that me... | 21 | Death Note Rule 27:
> If you write, "die of disease" with a specific disease's name and the person's time of death, there must be a sufficient amount of time for the disease to progress.

[Marvel] Has Deadpool ever sought an adamantium skeleton | Has he ever tried to find someone that could reproduce the bone coating process? | 26 | No, and he wouldn't.
First of all, Wade is a victim of the Weapon X program as much as Logan is. They lied to him, used him, and when he didn't turn out the way they wanted, he suffered horrible tortures at their hands and wasn't even allowed to die. Doubt he's going to sign up for more.
Second, he probably wouldn't ... | 56 |
ELI5: How come sometimes when we look at words they look like they're spelled wrong even though they're not? | 71 | This is the phenomenon called “wordnesia”
It is a brain glitch where words don’t look like words. And sometimes become scrambled or you can’t understand what they mean or how they’re spelt.
Reading words is pretty much just on autopilot in your brain-so when you actually try to look at the words-and overlook at the... | 42 | |
[Star Wars/Rogue One] Did the Empire/First Order ever find out the Death Star I was sabotaged by Galen Erso? If yes, did they adjust the Second Death Star and/or Starkiller Base? | 27 | Yes.
The second Death Star improved on its predecessor's design by incorporating millions of millimeter-sized heat-dispersion tubes in place of the two-meter-wide thermal exhaust port exploited by the Rebel Alliance at the Battle of Yavin. | 46 | |
ELI5 What Calculus is, and what it's used for. | I've heard of it, and the most I understand is that it's advanced maths, insanely hard, and some of the stuff I learned at GCSE (Age 14) can be done much faster with it. Unfortunately, past age 15 (I'm now 22) I didn't learn any more maths - I did French, Spanish and Politics A Levels, and a degree in the same. I'm not... | 59 | Imagine someone is walking, but according to very strange rules. On their first step they travel one meter. Every step after that is then half the length of the previous step. That means the second step is 1/2 a meter, the third step is 1/4 a meter, then 1/8, 1/16, 1/32, etc.
It's not too hard to figure out how far th... | 27 |
ELI5: Why is different kind of beers served in different kinds of glasses? | I've always wondered if the different glasses actually effect the taste in any way, or if it's just a cultural thing. | 23 | Much the same reason wine is served in different glasses.
Glass shape and size changes how aromas are presented to your nose. Smell is a huge part in the taste of things. Hops is very aromatic and the type of beer has different volatile compounds from the type of yeast used in fermentation that affect the flavor and s... | 15 |
[Halo 2-3]How would the battle for Earth have played out if the Master Chief succeeded in assassinating Truth aboard the keyship? | 26 | Not sure if you're aware of the comic series *Halo: Uprising*, but there was a segment in the comic where the Chief had the Prophet in his ironsights with a Carbine. A sneaky Jackal stopped him and the Brutes almost killed the Chief.
But had the Chief successfully killed the Prophet, it would probably had a destructi... | 24 | |
CMV: Restaurants should list lettuce as an ingredient | I hate lettuce. I hate it so much.
I hate the texture and the taste, I hate how quickly it spoils, I hate how it ruins leftovers by turning yellow and slimy, and I hate how it is often used as a filler, and I hate how when it is shredded it is inpossible to pick out of what I am eating.
I will often go to a res... | 35 | >Restaurants would never include unlisted meat or cheese ingredients due to dietary restrictions
Due to allergy or potential religious conflicts*

CMV: Capitalism is a greedy killing machine and it's not okay. | The Left vs right politics war waged on humanitarian leaders by greedy elites (oil billionaires mainly) who need extensive therapy and mushrooms (and quite possibly a hug)
Let me explain
Mental health awareness is purposely suppressed in America because it's "bad for business". The more people that become aware of th... | 28 | In the past two centuries, capitalism has raised more people out of poverty and into middle class prosperity than any other system of economy. Yes, it is the worst system, except when you compare it to all the others. | 69 |
ELI5: How does a Photon have momentum if it has no mass? | 178 | Because energy and momentum are proportional to each other.
Einstein's full equation is:
E^2 = m^2 c^4 + P^2 c^2
Note that if you simplify it for a non-moving particle, the second term goes away (P is momentum, and no movement means no momentum), you get:
E=mc^2
However, if you simplify for a particle with no mass... | 134 | |
How high would punitive damages have to be for it to no longer be profitable for landlords to illegally withhold security deposits? | 33 | There’s obviously no single number to give you that would answer this question. In deciding whether to take any illegal action, you weigh the chances of getting caught, chances of getting punished if accused, and the actual retribution for your actions.
In a civil-suit situation, as this would be, you also have to co... | 14 | |
ELI5: How does a hand drawn animation company keep drawings of people, places, and things consistent with a big animation team. | Companies like Disney create movies with 50,000+ hand drawn frames. How does every animator drawn the same character/place like every other animator on the team? | 283 | You are touching the surface on why hand drawn movies are so difficult to make and why the Disney productions were so loved.
They reuse the still after it is drawn once. If they need another angle the original still is used for reference. These stools are larger than the frame and you can move them with the shot to ge... | 166 |
Why don't I get an infection when I bleed from my ass? | If shit touched a cut anywhere on my body but my ass, I would be incredibly likely to get an infection.
If the tiniest bit of shit gets in my urethra I get a UTI.
Why don't I get an infection when I pop a hemorrhoid, or just rip my ass taking a ridiculously large dump?

[Harry Potter] The mystery of the Heir of Slytherin. | Spoilers...
In Harry Potter and the Chamber of Secrets a monster is unleashed at Hogwarts because the Heir of Slytherin has RETURNED.
To me it would seem that the heir would, to have made the beast active simply by their return(at least to the eyes of the trio), be a first year student or even a new faculty member.
... | 16 | There are a lot of reasons not to make that assumption. For example the heir may have needed to find the chamber then prove their cleverness to open it and claim their inheritance, that could have taken years. Next there is the idea that it was voldemort that passed down the knowledge, they knew he was active so he may... | 19 |
What are Schopenhauer's views on suicide? Did he support and justify the idea given his views on reality? | 21 | He was opposed. He thought that 1.) suicide was an optimist's view-point, since it was based on the expectation of something better that ought to have happened to one having happened, and more substantially 2.) since representation was just a manifestation of will mediated by the intuitions and causality, any attempt t... | 34 | |
ELI5: Why does adding n number of odd numbers yields n^2? What theory is being applied? | For example 1 + 3 + 5 + 7 = 4^2 | 16 | Imagine a square of one unit by one unit. This has a total area of one unit squared, or 1^2 = 1
Now imagine adding one layer to the top and right side of the square (not forgetting the corner, so it stays square shaped). This is now 2 units to each side, and a total of 4 unit squares. This is 3 more than before. The t... | 31 |
I think increases to minimum wage would INCREASE profits for low margin businesses. CMV. | Recently, while reading another post, someone stated that low margin businesses couldn't survive an increase in minimum wages, and gave the following 2 numbers.
Typical Grocery store has 1% profit margin.
Typical Grocery store runs a 'sales per labor hour' of $150.
It seems to me though that if this is the case, the... | 47 | **Costs**: Increasing minimum wage by $10 increases costs per hour to the employer by *more* than $10, as there are costs that increase with the wage of the employee (such as worker's comp and unemployment insurance).

ELI5: How do earphones produce adequate bass despite their size? | 107 | Proximity to your ear. The volume of air displaced by a large subwoofer is large, but it is many feet / several hundreds of feet away from your ear. If you are too close to something of this size, you will be doing damage to your ears because the volume of sound waves hitting your eardrum is too large.

ELI5 : Why is it illegal to fire a professional athlete in "work at will" state? | Why is it illegal to fire a professional sports athlete and not pay the remainder of their "contract" if state law says they are employed in a work at will state? Employers in "at will" states have the right to terminate any employee without having to prove just cause. How is this any different?
For example, I live in... | 148 | "work at will" doesn't mean that employment contracts are void. It means that there isn't an implied contract. Just because you get hired doesn't mean the employer has to prove just cause to fire you.

Where do the abs go during a pregnancy? Up, down, front, back? | 26 | The uterus is posterior (beneath) and inferior (below) the abdominal muscles. So during the period of pregnancy when a woman is "showing," those muscles and their connective tissue get stretched out in her abdomen, just like the skin on her belly does. They don't really go in any one direction, they just kind of "infla... | 39 | |
[MCU] Are Ironman's Nano tech suits more powerful that solid suits? | We see that the Nano tech suits are powerful and adaptable but do they have more raw power than a suit made of solid plates with purpose built guns? | 39 | That depends a bit on how you measure “powerful”.
First is the output of the generator / battery. It’s safe to assume that is higher. But we don’t know if the nanotech suit is more energy intensive in rest. So actual usable energy might be lower. It id be inclined to say it’s higher because…

CMV: I think it is ridiculous for one ethnic group to be indebted to another based on the actions of people who've been dead for hundreds of years. | ~~For example - government funded benefits to people with even small traces of Native American genetic makeup. Is this really justifiable? Are the taxpayers who are funding these people's free income really responsible for the actions of men who lived hundreds of years ago - who they may not even have any genetic relat... | 132 | The actions of people who have been dead for hundreds of years can have lasting effects if not adequately remedied. Don't think of it as necessarily a debt tracing back hundreds of years - think of it as an attempt to remedy a current inequality, the reason for which we acknowledge to be some past cruelty. | 64 |
What would you call the class of people who are low on cultural capital? | Terms like working class and proletariat originate in, and are better suited for, class systems divided by access to economic capital. However, I think that these days class is more defined by access to cultural capital (e.g. education, elite culture). What would you call the new lower class in such a system? | 65 | Why do you feel that this concept of "cultural class" is more relevant today than economic class when one can still so distinctly associate social power, influence, and wealth with how a person makes money (Selling labor-time vs owning capital)? | 33 |
ELI5:What would it take for a rocket shuttle to use electricity and not fossil fuels? | Im playing space engineers currently and it struck me weird as to the fact that the rockets in that game dont seem to use any actual fuel other than electricity in battery packs, so i wanted to know that if we ever get far enough to use anything other than fossil fuels, what would it take for a single rocket carrying t... | 32 | The issue comes down to Newton's Third Law of Motion.

ELI5: Why are untested medical treatments not allowed to be used when no known treatments work and the patient is sure to die? | If a patient is suffering from an illness, all available treatments have failed, and death is imminent, why can't the patient consent to be treated with untested treatments or drugs that may save them? Are there laws against this, and if so, why? | 25 | Terminal patients are allowed to take part in clinical trials using experimental medication. The catch is that these trials need half the patients to be secretly given placebos so there is a control group to compare against. Some states have passed "right to try laws" which allow terminal patients to have access to pla... | 10 |
ELI5: Why do white Lego bricks turn yellow-ish over time? | 90 | Some plastics are not UV stable (ultraviolet light damages or degrades the material), look at stuff that sits in display windows hit by sunlight for extreme and obvious examples.
This causes discoloration over time (and/or cracking), either fading of the color or whites yellowing. | 71 | |
[star wars: revenge of the sith] what was happening on the surface of Coruscant during the battle above It? | 24 | Mostly a running battle between CIS intrusion groups hitting strategic targets, and disoriented and ill-prepared Republic and Jedi forces.

We are in our most natural state as children. It is the job of educators, parents, governments, and other authority figures to beat the shit out of your inner child, so they can turn you into a mindless zombie who acts out some absurd idea of "this is what an adult is supposed to do." CMV. | Why are children so joyful and carefree, while adults are often such miserable sacks of anxiety, depression, or some other form of psychosis? I believe that decades of learned repression are responsible. It all starts in the classroom with "Sit down Johnny, stop throwing that pencil at Suzy!" But after being told over ... | 142 | What you're basing this post on is called an "appeal to nature" and in short is a fallacious valuing of the undeveloped over the developed.

Since economics is often considered the “dismal science”, what are some truly interesting/fun facts about Econ? | 23 | There have been many strange applications of economic knowledge.

[Sociology] What are more recent theories regarding elite opinion and opinion leadership? Is Lazarsfeld/Katz' "two-step flow of communication" model still the most prominent one? | As a historian, I want to make use of the "two-step flow of communication" theory. As it's over 50 years old now, I'm wondering if it hasn't been superseded or heavily criticized by now?
Also, can you point me to some more recent books or articles on elite opinion and opinion leadership?
Thank you! | 29 | well, lookey here, something i know about...

Believing in Santa is one thing, but sacrificing an animal or part of your harvest to appease him is another. Anthropologists will find alters or walls covered with figures or spirits. At the base they'll find things like animal bones or clay jars with evidence of decomposition in the so... | 18 | |

[Babar] Is Babar's Kingdom (Celesteville and surrounds) essentially a puppet-state for the French colonial interests? | 29 | Not exactly. Babar isn't directly controlled by the French, but the fact that he has been "civilised" by his time spent among them gives him a skewed worldview which leads him to believe that the interests of his people are best served by close collaboration with their foreign "allies".
The French are able to take adv... | 17 | |
ELI5: I didn't cough while i was smoking but now I've quit for a week and i can't stop coughing. Why? | 39 | There are little hairs in your lungs that help clean by moving mucus in the lungs. When you smoke these hairs stop working as effectively, but when you stop they start to heal and clean, so you'll experience coughing/tons of mucus as your body catches up. | 64 | |
ELI5: What happens between the gap of about the 5 or 6 months when a movie trailer is first released, and the opening theater date? | At this point is it just building hype or is there any strategic way the producers collect feedback and change stuff prior to the release?
Just curious.
Thanks! | 385 | Actually in many cases, when you see the trailer, the movie isn't anywhere near done.
It looks like they finished the whole 2 hour movie and you're seeing a selection of 2 minutes of it.

ELI5: In the USA, why does the FCC allow all of a female breast to be shown on public TV, except for the areola and nipple? | 19 | It's because cleavage, and even side boob, are apart of normal clothing for women to wear.
