Why do photos of other planets look fake? | One reason is that you have likely seen a bunch of 3D renderings or other artistic representations of planets and have accepted that to be normal, so the truth looks strange by comparison.

How do engineers get different amounts of horsepower out of engines that have the same number of cylinders without adding turbochargers etc? | Power is roughly proportional to displacement * RPM. So you can either optimize the engine to run faster, or make the cylinders bigger. So you'll get racing engines that are small and light hitting 20k RPM, and you'll get ship engines that are huge and heavy at ~100RPM. More cylinders lets you increase displacement wit... |
Why does the moon appear translucent during the day? | It's not translucent, you are just seeing it through the atmosphere. At night, sunlight doesn't reflect off the atmosphere, so the sky isn't blue and the sky isn't getting in the way of your moon-viewing. |
Why do people trust journalists when they say off the record? What's stopping the journalists from printing what they talked about? | A journalist's reputation is important - if they can't get people to give them information, it's harder for them to do research and write articles worth reading. So they might be able to print something that was supposed to be off the record once or twice, but then they've ruined potential future interviews. |

Why Does Every Contemporary Christian Rock Band Sound Like A U2 Tribute? | Most Christian rock sounds nothing like U2 but if we are talking about Worship music then that sounds about right. Reason 1: Big sound. The big delays and reverbs make it sound huge without having the whole Gospel Choir. U2 pioneered this sound for the mainstream. When you are doing the whole hands in the air thing hav... |
Why would erasing everyone's debt be a bad thing for the economy? | Probably because, after that, there would be zero motivation for anyone to lend money to a stranger again, whatever the terms. If one wanted to slow down the ecomony into a very long, brutal depression -- the kind where vast parts of society don't have work or anything to eat -- this could be the the absolute best way ... |
why can I move my ears? Is there an evolutionary reason behind it? | It's something of a vestigial trait for humans, but for many animals moving the ears allows for better detection of the sound's direction. |
Why hasn't the RJ45 port (Ethernet) changed much over time? | But hasn't it? HDMI and Thunderbolt can send network over their cabling. Fiberoptics? While the plugs haven't changed, the cables themselves have with things like Cat 5 vs Cat 6. Next, very few have a network that uses the full capabilities of the cable. Then you got electronic devices turning to Wifi. There just hasn'... |
How is FM radio still thriving as much as it supposedly is as a media source? | digital radio is becoming more common, but it still pales in comparison to the number of cars that have a plain old FM radio receiver. My cars aren't exactly new, they're both about ten years old and they have standard FM/AM radio receivers, and every radio I encounter at work is FM. One or two people have personal DAB... |
Why do some people's personalities completely change when they are drunk? | Alcohol F's with your judgement. If you're easy-going, and you're aware of that, then that means you know what douchy people are like and that you shouldn't do that. If you're drunk, you tend to act on what you're thinking more carelessly than you would sober. It also tend to dumb you down a bit. You basically become m... |
Why doesn't Reddit ban overtly racist subreddits dedicated to hate speech or the pedo subreddits? | Because racism, whether you like it or not, is perfectly legal. Reddit doesn't pick and choose which subreddits they allow or disallow, which is the key to Reddit's success and popularity in the first place. Reddit *does*, however, ban any subreddits with pedophilia content, since that is *not* legal and poses a huge l... |
Why LFTR (Liquid Flouride-salts Thermal Reactor) are not used today? | While the LFTR have been experimented with since the 1950's, there's still too many unsolved technical problems for them to be economically feasible. Probably the biggest problem is that exposure to nuclear fuel causes corrosion. In a traditional uranium reactor, the fuel is relatively isolated so this is less of an is... |
How does ISIS keep finding Westerners to hold hostage? Why do Westerners keep going to areas where they know there is a risk of capture? | I'd like to know how Westerner or anyone else in the world gets in contact with them or even why they would look to make contact. Is there like a ISIS 1-800 hotline I don't know about? |
Why protesters against big companies, are allowed to block traffic and inconvenience average people. | If they have obtained a permit, it's because they've followed the process for use of shared space. More commonly they have not obtained a permit and are breaking the law. However, arresting large mobs of people is fairly difficult. It requires significant police resources and the police inevitably end up looking like t... |
Why can't America deploy the National Guard to areas like South Side of Chicago to help with the overwhelming crime rate and eventually restore order. | Each state's National Guard is under the control of the state's governor. He could, in theory, deploy the Guard to these areas , but I find it highly unlikely due to politics, cost and inconvenience. Remember that Guardsmen are part-time and have lives, and careers outside the Guard. Something like this could be a huge... |
Why did QR codes seem to die out? They could have made things so easy if phone manufacturers supported them. | It's not something phone manufacturers need to support - there are virtually no smartphones out there that you can't install a barcode reader on. QR codes were a lot more popular in Asia than in the US. They just never caught on here because, well, I suppose people didn't see much point. You didn't get a lot of extra v... |
How are tattoo artists not violating copyright laws? | Going after them would be penny wise and pound foolish of the people who own those copyrights. More beneficial for them that there's a human being out there with advertising tattooed on their skin for their product/show/service/movie/etc. |
Why the Mona Lisa is so coveted? | Another factor is that there aren't many da Vinci paintings in existence. Wikipedia says 15, some of which are disputed and others are in bad shape or unfinished. So a da Vinci in excellent shape would be a centerpiece of any museum. _URL_1_", 'Also the first use of the renaissance painting technique, atmospheric persp... |

The Soviet Union wanted a pro-Russian K... |
How would our current immune systems be affected if we were to travel 200 years back in time ? | You'd likely have some imunity to the big killers, as you're genes are mostly going to be from those who weren't killed off by them.

How do pop musicians score a chart topping hit on the release of their first album, and go from nobodies to ubiquitous in a matter of weeks? | The process and resulting growth is made to look as organic as possible, when really its the producers, Co-song writers, label and its executives who try and pick out a succession of what they believe to be winning singles.

How the hell does a calculator gets the square root of pi in no time? | Pi is a constant, so it is hard coded into the calculator. The calculator doesn't need to calculate it every time, and it doesn't need to store more than 10 digits or so. The square root is calculated using approximations and trying to find closer and closer numbers. You're looking for a number x such that x^2 = pi, ri... |
How come people have more trouble balancing with their eyes closed, even though a common method of balancing involves staring at the same point and not averting one's gaze? | If your eyes are closed you can't see anything.

The current situation in Venezuela | My sister-in-law moved here from Venezuela years ago but her family still lives there. Her brother just recently escaped to come live with all of us in Canada.

How did great warriors and leaders in history survive battles all the time? | As other people say, in many cases they stood back.

Why aren't medical marijuana costs covered under healthcare? | Insurance only covers things that are medically necessary. This means evidence based research shows that a particular treatment is effective. This doesn't exist for medical marijuana. This is partially because doing such research has been nearly impossible. |
Why not instead of going after illegal immigrants the U.S doesn't go after businesses and people illegally hiring them? | Most of the illegal immigrants I've known didn't come here illegally. They had a visa, which expired, and they stayed. The ones I knew had jobs, and I'm not sure if they got the job while their visa was current or if they simply still had whatever they needed to get a job from when their visa was current. Oh and some o... |
What happens when someone gets hit on the head so hard that they pass out? | The brain is like a very firm jelly. When you shake a plate of jelly it wobbles right?

Why do meal combinations become "boring" and unpleasant over time? | I think I'm the only person I know who doesn't get bored with food. I eat the same foods almost everyday. I'm very picky, so that probably has a lot to do with it. It's not to say I don't enjoy foods that I haven't eaten in a while, but if I were to only have access to the pepperoni and turkey sandwich with tomatoes, p... |
Why is a physical standard still needed for the kilogram? | > However, do we not know the masses of enough things in kilograms where you could just cross-check to determine mass rather than have a standard? If you measure precisely enough, things are always going to be a little off. If you buy two 1-kilogram weights and weigh them very precisely, one is always going to be sligh... |
Why are trick plays in American Football so rare? | You know what you call a trick play that works? A play. Trick plays involve taking more risk, by increased complexity and by having players do things they normally don't do.

What's happening with this potential government shutdown. | Would teachers at schools be furloughed? Would it just be staff? Would it be the people in control of the ED department? What about free school lunches??? I searched google and found this: _URL_11_ which is the Emergency ED Planning for Potential Government Shutdown. It's still not 100% clicking in my brain. |
If we use an exclamation point to show we are yelling, why isn't there a symbol for whispering? | ^^^^You ^^^^mean ^^^^there ^^^^isn't ^^^^a ^^^^symbol ^^^^for ^^^^that?", '*I thought italics kind of work* *MaybeItalicsWithoutSpacesAreBetter* *or-Italics-with-hyphens?* Nope. None of this is working. Much disappointmentCaps indicate telling, exclamation point indicates shock, excitement, wonder Typically what I use ... |
Can we code an operating system from scratch using an empty PC? | Not with a modern PC. The earliest computers could be programmed by setting switches and loading data into memory. You can make a simple programming language this way and then make more complex programming languages. But it's easier to use a different computer to program the OS and then put that on a disk. |
Why are movies so poorly written compared to TV? | You are being very unfair. You are remembering the great TV shows and throwing out the many many more bad ones.

Why is there such a large architectural diversity in Detroit? | Downtown Detroit consists mainly of buildings built between late 1800's and the 1920's.

Gradually as the city built out from downtown you can see the difference in which ... |
Why are some pimples really painful, and others are not? | Gonna take a guess at this and say that the pain is a result of inflammation by the immune system in the local area to reduce bacteria numbers.

Why is fighting against a enemy using Guerilla Warfare so hard? | Traditional warfare tactics are basically that your army marches to their army and you shoot. Guerilla warfare is that their army marches to your army but you're not there. Whenever they try to march, though, you pick them off a few at a time at little risk to your troops. Thus, tiny guerilla bands can annoy large armi... |
Why aren't people getting sick from using their phones in the bathroom? | If your own poop has hepatitis in it, then **you already have hepatitis**. You probably should not lick strangers' phones. Especially not if the stranger has hepatitis, and the phone is covered in poop. |
When scientists look for life on other planets, why do they look for things that humans need to survive? | Same reason that when you drop your keys, you look in the gutter, not down the sewer. If they are down the sewer, your aren't going to be able to find them, so why bother to look? The same applies to searching for extraterrestrial life. We know a whole lot about life based on carbon and water, and know what kind of clu... |
Why is it that when my internet connection is poor, whatever video/stream I am watching lags terribly, while the advertisements before it are perfect quality? | Adverts are short and don't play until the whole thing is ready. Films are streaming and if your internet is slow it drops the quality in preference to pausing while it buffers.YouTube has their own Content Delivery Network . That is, they have servers all over the place that are preloaded with popular videos, so that ... |
Where did the notion of Korean fan-death come from, and why do they STILL believe it? | I think there are many things that contribute to it being part of the cultural imagination. In Korea the standard heating system is radiant floor heating. In the olden days it was coal braziers under the floorboards of wooden buildings , then in the 1970s there were attempts to use coal burning heaters in multi-floor b... |
Why do car air conditioners need to be recharged, but home units (window, central air, etc) can be used continuously? | The same thing happens to home AC units. The main thing has to do with the rubber seals. If the AC is unused then the seals dry up and can leak. Most recharges also include some seal conditioner in it. Also as a side note this is why you should run your AC in both your car and home at least every 3 months. It rehydrate... |
Why does slurping a hot beverage make it feel less hot when drinking it? | Not an expert, but I assume when you're slurping you cover all the liquid surface area going into your mouth with air, so it's being cooled down as it goes into your mouth from the container. Hope I'm of some assistance! |
Why do children communicate by shouting? | Why we're on the subject of shit little kids do, why do they have to run everywhere they go? |
Why dont the eyeballs of animals like snow leopards that thrive at -30 degrees freeze over? Do they just blink every millisecond? | I know nothing about eyeballs but a few things about heat transfer. It takes a lot of energy to change the temperature of water because of it's high heat capacity. It also takes additional energy to change the phase of water. Basically this means water can loose a lot of *heat* before it changes *temperature*. Also wat... |
How does a refrigerator generate cold? | Cold is just the absence of heat . You can't generate cold, but you can move and concentrate energy. A refrigerator takes energy from inside and moves it outside. |
Why are waiters/waitresses paid below minimum wage in the U.S.? Isn't a tip not a tip anymore when you're essentially paying their living wages and subsidizing the restaurant's payroll? | It should be mentioned that the minimum wage exemption is conditional.

What is Amway? Is it a scam? | Their sales model is .odd and has made me uncomfortable in my few experiences with it.

Why do all sci-fi space helmets now have ambient lights on the inside? | Film is a visual medium. Actors act with their faces. So they want to make sure you as the viewer can see their face while they act. So they put lights in the helmet so you can see the actor's face. You wouldn't want that in a real space helmet because it would be harder to see. Because the astronaut would be looking a... |
Why are external hard drives so much more expensive than relgular hard drives? | That $200 drive is either made out of gold or a horrible fucking deal. You should be able to get an external 500GB drive for $70-80, easy. An external drive might as $15-20 to the cost of a drive, more if it's a particularly fancy enclosure. |
Why isn't telemarketing illegal? Or if it is, why is it still so frequent? | 10 years in the industry. Nobody cares about the DNC list. No one. We used to call them because for the most part they aren't being badgered as much so they usually would be nicer! Go figure. There are a million ways around the DNC list also. The number we would pulse would be from a throw away phone from 711 register ... |
How do camera operators in golf games track golf balls? They seem impossible to track in real life | I was just at the PGA championship. We sat at hole 14 through most of Saturday afternoon, and when the leaders and big names started to come through, so did camera crews. Here's what we observed. Cameraman lugs massive camera out to a pre-determined location, and an assistant brings a tripod that looks like it could su... |

Why must a country "declare war" before attacking? | You don't have to, but there are international laws that govern this stuff. If you look like a mad dog; other countries will band together to either keep you on a leash with a close eye, or truly fear you and aim to put you down. On a related note, a lot of things that get labeled as wars to the public are in a politic... |
Why is it so difficult to make "perfect" software? | You've definitely identified the trade off. Software developers are torn between getting to market quickly, and improving quality. The market tends to reward new features that mostly work. Getting in early and then fixing things is usually better for business than waiting until things are higher quality . |
If it's possible to build up a sleep debt, is it possible to build up a "sleep credit"? If not, why not? | I think you can compare this with rechargeable batteries, if your batteries are full, even if you leave them on the charge when they are full, they won't last longer.You can run out of gas but you can only fill your tank to 100%.There's a lot of stuff done during sleep, like muscle repair and forging new pathways in th... |
How do spacecraft that travel great distances in space keep from being destroyed by debris? | [Whipple shields.] Debris in earth orbit is a real problem-- a lot of it is travelling at high speed. If this hit something like a satellite, space shuttle or god forbid the ISS, this would lead to something called Kessler Syndrome-- where more high-speed debris is created, which takes out more satellites and more unti... |
What caused the water to disappear (and in what manner will it return) from the Bahamas coast? | They storm is a low pressure system. The center sucks water up. Think of it like a straw.The water has to come from somewhere, outside of the center of the storm.So there's a bulge of water under the center of the storm, and lower water around the outside. |
Why does my breath stink in the morning even though I brushed/flossed/mouth washed before i went to bed? | Because it's still ~8 hours ago. Brushing and flossing don't completely rid your mouth of bacteria , so they will continue to grow and multiply in your sleep. And since you aren't doing anything else to combat that or alter your breath, the only thing in your mouth that could cause a smell is that bacteria.you know how... |
It's 40°F/4.4°C and snowing right now. How is it not raining instead since it's well above freezing? | Temperature changes with elevation, basically every 1000 meters you go up it drops 6 degrees centigrade the snow just hasn't had time to warm up, hail falls on even hotter temperatures than snow. _URL_0_", 'Its 4 degrees at ground level, not in the atmosphere where snow forms. It just means it wont stay on the ground . |
What's the ringing in my ears when everything is silent? | There are little sticks in your ears that move back and forth with sound. When your listen to something too loud for too long, those sticks can become damaged, in a state where they're permanently leaned over.

Why are big cats such as lions or tigers able to be trained in extravagant shows while domestic cats rarely even acknowledge their owners' authority? | I've tried training my cat to fetch and to sit up, to no avail. But her lounging and clawing-at-my-couch skills are on point. |
Why would Israel release over 1000 prisoners for 1 soldier? | I had a Jewish friend tell me once that it's a fairly fundamental tenant of Judaism that you can't put a price on human life. But don't take my word for it.. |
Why is IE so hated? Is it really that bad compared to chrome/Firefox? If so, why hasn't Microsoft improved in all these years? | Microsoft made IE incompatible with the rest of the internet in the hopes of preventing competition from Firefox/etc. So whenever you designed a website, it looked fine in chrome/Firefox/Safai, but broke in Inernet Explorer. Sometimes you had to leave cool features out because stupid IE couldn't use them. It isn't as b... |
If your body is constantly replacing skin cells with new ones, why do scars last a long time? | When I was five it was explained to me like 'The new cells replace the old ones one by one, just like if you build a house out of lego that has a defect, if you only remove one brick at a time and immediately exchange it with a new brick located at the same spot, it's always gonna look the same. |
Why are foxes not a popular pet to have, they're like a mix between a cat and a dog | They're not legal to have. Animal rights laws prohibit the domestication of new animal species as it requires cruel practices to achieve. Russia has soldiered on, and while they have managed to breed friendly foxes, there is still quite a bit of animal cruelty left before they've bred foxes that are house trainable. |
How do journalists find people? | They often can't find people. And when they can't find a person, they don't write a story about it, and you never know about. If they look for 100 people, and only find one, you only get to read the story about the one they did find. |
Did humans have breeding seasons? | Hmm, I'm no expert, but I'm studying birds this semester and their internal time clocks say it's breeding time when the right food is available. For humans, there is food year around, plus I could see having a mating season individual being beat out of the gene pool by someone who can mate all year around. If there wer... |
Why do Californians still bother with lawns made of grass that dies in their climate? | Because people often lack foresight, even when a problem is staring them right in the face.

When we feel drowsy, why do our eyes lose focus first before any other senses? | We just tend to notice eyes first even when other senses are losing focus, as numbness in your limbs, or when people have to repeat what they said because you weren't listening. Also eyes have mechanical shutters that make quite obvious the loss of focus. |
Why aren't polygamist rights treated similarly to gay rights? | It is pretty much a cut and paste job to include gay marriage into the existing legal framework for marriage. Plural marriage is a lot trickier. Divorce, property rights, parental rights, not only are they inherently more complicated, but they lack the centuries of legal precendence that produced the modern marriage fr... |
Why is it cheaper to imprison someone for life than to give them the death penalty? | * we want to be really, really sure we don't execute someone we shouldn't have, so we give people on death row every chance to appeal* there are highly motivated people who oppose the death penalty on moral grounds, who make legal resources available to the condemned that wouldn't be available to those merely sentence ... |

Why are most modern houses built with wood frames? | Wood in North America is cheap, plentiful, and fairly strong. Concrete and steel reinforced is stronger, but more expensive. You don't get a McMansion for $300,000 with concrete. Concrete is relatively more popular in much of Asia. There are also aesthetic considerations. Some people just think concrete looks stark and... |
Why does my stomach still hurt in the same place after my gallbladder's been removed? | this is kind of late but i hope you see this- it might be worth checking it out at the doctors and getting an ultrasound done, if you have the moneys for it. i've heard that you can actually form gallstones in your liver post-cholecystectomy, if you have a super-shitty diet.Not a expert, but it may be similar to phanto... |
Just exactly what is the conductor of an orchestra doing and how is he/she doing it? | I haven't studied music or anything but I was a percussionist in band all the way through grade school.
