Why are people so against taking in refugees in Canada? | Many people believe the government will be accepting refugees too fast to adequately screen them.

If we pay for cable why do we have to watch advertisements? | Pretty sure I remember my parents saying that cable originally didn't; open air shows had ads but if you paid for cable you didn't have ads. Then somewhere along the line they decided to put ads everywhere. |
Why did China never suffer trade retaliation when it literally blocked US companies such as Google, Facebook etc from trading there? | One thing to understand is that not all industries are treated the same when it comes to trade and tariffs. Some sectors, such as financial services and agriculture, are protected far more than others. The reasons behind this are varied, usually political. So just because a country is protectionist in one area doesn't ... |
Why is the world just watching ISIS massacre people? | Why is the world watching North Korea Starve and torture Million more then are even remotely affected in the middle east?

Do you believe the world as a whole is obligated to interfere in matters they disagree with?... |
Why do we tolerate flaws and license terms in software that would lead to recalls and class action lawsuits in other products? | Because everyone will agree to those terms without even reading them. If you went to Taco Bell and had to sign a EULA, you'd be a lot more suspicious and less likely to eat their food. There are also laws governing what they can and cannot put in their food, but software developers aren't held to a similar standard. |
; Why do people concentrate on political win-ability rather than how honest the politician is? | We've become stuck in a system that votes for who we think would win instead of who we want. The person that wants to vote for someone takes into consideration that almost everyone else is going to vote for who they think will win. Thus, they give up and go with the flow. |
what is the maximum number of GPS devices that the network can support? | There's no limit. GPS works by satellites sending out a carefully calibrated time, and the the receiver's job is to work out from the satellite and time info where it is relative to the satellites. The satellites don't receive any signals, so there's no limit to the number of GPS devices possible. |
How does your body learn to stop peeing in its sleep? | When a person's bladder becomes stronger; the bladder is capable of holding a particular ounce of urine but eventually *must* evacuate.

Why are there big cities in places like the American Southwest but not in the Australian desert? | The big cities in the American Southwest grew up around road junctions, forts, and mining industries back in the 19th century. The Australian outback has basically nothing in it. There's no reason for anyone to move there. The Australian mining industry is relatively modern, and was established long after it stopped be... |
Why is there such a sudden surge in 3D printing on the internet lately even thought 3D printers existed years ago? | A 3D printer can be bought for under $500 now. Years ago you'd be looking at thousands of dollars for a machine so obviously not as many people would own them. A similar example would be HDTVs. They were initially well beyond the price range of nearly everyone, but then a handful of years later nearly every household h... |
Why do sports teams have "home" and "away" jerseys that are different colors? | To take an extreme example where there aren't enough combinations, there are 736 teams competing in the English FA Cup, any of which could in theory play any other during the competition. Even if you restrict yourself to making kits unique enough within each league, good luck deciding which of Manchester United or Live... |
If an engine has 200 hp and 350 lb/ft torque and another has 300 hp and 250 lb/ft torque, which engine is more powerful and why? | ELI5-style: Torque is the ability to pick up a 500-lb weight. Horsepower is the ability to pick up 5 100-lb weights in the same amount of time. Way over-simplified, but that's the idea. Race Cars tend to be high-horsepower, but not so much torque, because Speed Kills . On the other hand, on short tracks, high-torque en... |
Why can't anything escape a black hole? | You can escape Earth's gravity if you accelerate hard enough; but the amount of force required to escape the gravity of a black hole is impossible to achieve. Think of it like trying to swim against a super strong river current; your best effort would not be enough to defy it < : |
Kid just asked why, if fire needs oxygen, can you blow out a match? | The short answer is that it has little to do with depriving the flame of oxygen. An easier example might be your gas stove. You can blow that out, too, but it's a little harder than a match. The flame you see is composed of burning gases. When you blow on it, you spread out those burning gases. The burning gases are no... |
Why does fresh air usually keep me from vomiting? | I'm also emetophobic , and I can attest there are ways to talk yourself out of vomiting if you suffer from this phobia.

If someone wants to modify a behavior intentionally, yo... |
If inside my house is 60° in the summer it feels nice. If it's 60° in the winter it feels cold. Why? | It is the opposite for anyone I've ever talked to. 72 indoors feels cold in the summer and 72 indoors feels hot in the winter.ITT, Americans taking about temperatures casually while the rest of the world wonders how anyone could find 60ºC *cold*', "For the same reason it feels different in winter when it's sunny or whe... |

Why would a company spend money making offices in a leased spaced. Doesn't the landlord "own" and benefit from all of the enhancements? | Leasing allows you to pay for flexibility. Businesses often have needs that change rapidly from year to year, and leasing allows you add or change space more quickly and less expensively. It also lets you start a business more easily, as you avoid loans and big down payments. As for the enhancements, who owns what and ... |
Why is it that every once in a while, a breakthrough in Alzheimer's research and sometimes even a cure is announced, but in most cases, nothing happens after? | Two reasons. One is that the media is populated by those with art degrees, which means that the stories are written by people who don't know *anything* about *anything*, and have a big incentive to be sensational to draw readers. So obviously they badly misinterpret and misrepresent any scientific advancements. The sec... |
Can someone explain the 'Aristocrats' joke LI5? | A guy walks into a talent agent's office and says I have a show for you! My family comes out on stage and starts dancing! My wife dances the chicken dance while my son dances YMCA! My daughter and I dance a tango while our dog howls the happy birthday song! Then we all fall down a trap door into pudding! The agent asks... |
One aspect of 3D printing I can't wrap my head around | 3D printers have a print head, much like a paper printer, and it squirts out some material, like a paper printer squirts ink. This material is going to come from a hopper mounted above the print head, or perhaps a liquid is pumped through a hose. The cheaper end uses a plastic filimant, like a plastic string, from a sp... |
Why don't toilets have an overflow hole to keep them from overflowing all over the floor? (Like sinks do) | Toilets don't use a P-trap in the below floor plubming since you don't want fecal matter and urine sitting still.

Upon thinking a ... |

Most of the world don't eat dogs so their spread across Eurasia was probably for hunting/transport purposes. |
Why can't we use Cellulase, an enzyme that can break down cellulose (wood and grass) into sugar, to eliminate world hunger? | [Although people are working on it], producing cellulase on the scale you're describing, to feed that many people that much food, isn't more efficient than just growing edible crops in the first place. Also, your assertion that there's plenty of grasses to eat in the places where people are starving, I'm not sure is tr... |
Why are nationals laws such as the No Child Left Behind Act not amendments? | Passing an amendment is a much more rigorous process than passing a law. It's not a simple majority vote then an OK by the President; it must be ratified by 38/50 states to become law. It's a longer process, and more difficult. It's also something of a philosophical point, but amendments are supposed to guarantee very ... |
Can a red colorblind person visualize red in their head? Or is it just as abstract as ultraviolet? | People missing red cones are still sensitive to nearly as wide spectrum as the people with normal vision. The green and red cones have a huge overlap:_URL_1_ So it's not the same as ultraviolet, which doesn't register on your retina at all. They see red colour, but it's difficult to differentiate it from yellow and gre... |

Controlled burn and why it is necessary | Well, current research indicates that forest fires are beneficial, even required, for strong forests. However, the idea is that you can burn an area in a controlled fashion so that it can't burn later. Thus, you can make a large wall of already-burnt area where, should a fire start, it can't burn through, and thus save... |
If we die because our cells get old and useless, then why are old people able to create babies who have entirely "new" cells? | We don't die because our cells get old. We die because over time, the genetic information in our cells becomes damaged, and the mechanisms we have to repair our cells become less effective. The male reproductive system only has to deliver a sperm with intact genetic material- nothing else. In fact, it's so focused on g... |

Why do rovers such as the Mars Curiosity rover have wheels instead of tracks, like a tank? | It's not so much wheels as the rocker-bogie suspension that's key. It allows it to stay level as it climbs terrain, and to keep all of it's wheels on the ground. _URL_0_", 'Because even if it was tracks it still need to have wheels to guide and drive those tracks. It adds unnecessary weight, which is a huge deal for an... |
Why is there a sex offender registry but no murderer registry? | Murderers are much less likely to be repeat offenders than sex offenders. Murders tend to be one-off events based on specific circumstances whereas sex offenses are based on an overwhelming drive. There are exceptions in both directions of course, but that's the general reasoning. |
How does multiple personality disorder work? | The most common theory as to how DID arises is that it is a defense mechanism against child abuse where the child develops a personality that can deal with what is happening. However, this doesn't explain why sufferers can develop so many personalities, especially when some of them wouldn't seem suited to it. Additiona... |
If a room has something that plays a sound, but nothing that can hear the sound is in the room - does the sound really exist? | Sound is vibration. If there is a device playing a sound, it is causing vibrations whether or not anyone or anything perceives these vibrations. So yes, there is a sound. Just like there is sound that other people hear when you don't and sound that you hear that others don't, the existence of something is independent o... |
Why does the police force always seem to be filled with corruption but not the other emergency services? | It relates to the expression, 'Power corrupts ' Police are given power over the populace, while other emergency services are not. I used to be a firefighter and we weren't allowed to give instructions to the public except to tell them how close to an emergency scene they could stand. If we needed further restraint or c... |
How can prisoners be trusted to be close to teens on Beyond Scared Straight, and programs like it? | The interactions are closely supervised and the inmates that make it into the program are 'trustees' that have been deemed to be low risk.90% of prisoners are non violent drug offenders why would someone commit there 1st violent crime on camera? |
Why Don't Babies Just Sleep When They Are Tired? | It's neurological. They're getting a huge amount of sensory stimulus, beyond their capacity to organize the content and deal with it. They eventually do collapse into a state of near shock. The rocking, clucking, crooning, and nursing helps them to structure and organize that neurological sensory input so that they can... |
Why is 'E' the most commonly used letter in English and other languages? | Hi, I'm a linguist. Mostly one reason: we use it to represent so many speech sounds. For one, you've got silent e, which kicks up the count a lot. Then you've got e as in sled, e as in been, e as in bean, e as in shoe, e as in her, e as in here, e as in target, and a few other uses that are linguistic divisions that yo... |
With the progression of Automation within various industries, What would happen to the human race? | One thing to consider is that the manufactured products still have to be sold.

Why do some people think vaccinations cause ADHD and autism, and what caused this line of thinking? | I'm surprised it hasn't been mentioned yet, but I think some of the blame for the popularisation of this line of thinking lies with celebrities preaching about vaccinations, namely Jenny Mccarthy. Her son had allegedly Autism, until he was magically cured by the healthy diet and her earth-mother nurturing. Coincidental... |
How is it possible that certain theories in math (Euclid's 5th postulate, The Comparability Theorm) have been proven to be unprovable? | The easiest way to show that something is unprovable is to show that it is false. We did this with Euclid's 5th postulate . There exist different types of space where it doesn't hold. I haven't heard about the Comparability Theorem, so I can't comment on how they showed it's unprovable. |
Why are there so many movies made about the Vietnam war but so few about the Korean War? | Korea was shorter but almost equal in US military deaths. 11 soldiers died per day in Vietnam, 45 died per day in Korea on average Korea was also a very bleak war with out all the intrigue of drugs and the wild west attitude of the Vietnam war.

Why am I so tired when I wake up even after getting plenty of sleep? | Ahhhhhh. The most frequent answer you will get is sleep apnea. Look it up. I was young fit as it gets, but I would sleep for 12 hours and wake up exhausted. Typically, apnea affects the fat but it happens to the fit too. Talk to your doc.

How do people get away with selling so many fakes on eBay/Gumtree | In order to get caught for something like this, several things need to happen. 1) A victim needs to report it to the proper authorities. Local PD won't care, as it's not their job/jurisdiction. 2) The proper authorities need to care. 1 bad blender isn't going to get anyone motivated. 1000 bad blenders might. There are ... |
Why in old television footage do you sometimes see a ghost effect where the background is visible through the actors? | I believe what you're referring to is ghosting. You see a slightly offset video image close to the main one. It was due to to the video signal bouncing off of nearby buildings and structures and sending a second, slightly offset signal. I grew up on antenna TV in a rural area. The ghosting was actually more of a proble... |
Why is math so important? | Math is *the* language that we use in science to model the world around us. I'm a physicist, so you'll get the that approach. What a physicist does is translate the system that he/she is analyzing to mathematics. If you're able to do that you can start predicting what happens in that system without actually doing any e... |
Why do movie file sizes vary so much? | > I have two different versions of Apocalypse Now downloaded, the redux version which is 2.1 gigs, and the original cut which is 4x the size of the redux .

How are flies able to dodge such swift attacks thrown at them? It's crazy how fast they react and I've always been curious. | Another factor to consider is that the nerve impulses from the fly's central nervous system to their flight muscles have a vastly smaller distance to travel than the nerve impulses from your brain to your arm. Sheer distance does matter, since nerve signals travel at a set speed. The fly has the advantage of not only a... |
Why does time pass quickly when you enjoy yourself, yet slow down to a crawl when you are suffering? | Because when you are having fun, you don't pay attention to every second that happens, you are focused on just having fun, but when you are paying attention to every second, it is slow because you are are aware of how much more time there is and how many seconds/min/hours need to pass by |
What's happening in Fukushima | Not much. They're trying to reduce the amount of water leaking into the reactor, to avoid the amount of contaminated water they have to pump out and store. They're filtering this contaminated water, so that they don't need to store it anymore. This has been going very slow. They're gathering up the contaminated soil in... |
why do we sometimes stick out our tongues slightly when we're concentrating hard on something? | Tongue position also can have a big impact on strength. Here's an [ELI5 explanation] . Essentially, the tongue and brain are wired pretty tightly together, from a nerve standpoint. It's pretty cool! |
Why are death row inmates executed by lethal injection or electric chair rather than a gunshot to the head? | Because they can't make $50,000 dollars off of a bullet.We want things to look pretty. "States began moving to lethal injection in the 1980s in the belief that powerful sedatives and heart-stopping drugs would replace violent spectacles with a more clinical process while limiting – if not eliminating – pain." Lawmakers... |
When did eggs become stereotypically breakfast food? | So I didn't know the answer and the ones here seemed wrong, did a little googling.

Which kills us : Volts or Amps ? | Technically it's the amperes. However how many amperes flow through you depends on the voltage and your resistance. Without high voltage you won't get high amps but high voltage alone won't kill you if you are insulated well enough. There are several other factors as well. The first would be the path the electricity ta... |
Does keeping someone "awake", keep them from dying like in movies? | Keeping them awake doesn't keep them alive. Otherwise, every medic in the world would work on their conversational skills first, medicine second. It just doesn't work this way. It looks good, but ultimately these people slip into unconsciousness. If you've ever seen someone pass out, it's a lot like that. Talking them ... |
How are casinos going out of business? | there are 10 casinos closer to NYC than Atlantic City now. Outside of the casinos, it's a slum. |
Why is there snow and hail? They're both frozen water, but what's the difference? | Snow is a crystal. Atoms of water self-assemble on the crystal when the right conditions of temperature, pressure, and humidity are present. When the mass of the crystal becomes great enough gravity pulls it to the ground. Hail is a frozen droplet of water - it's not a crystal. Hail occurs when rain falls through a zon... |
What makes eczema incurable? | Asthma and eczema are coded on the same genes, which is why asthma patients will often have eczema or vice versa. It's *not* the same thing, as others have indicated, but it is very closely related. I don't know the exact numbers, but the chances of getting eczema go up exponentially when you already have asthma. As fo... |
If diamonds aren't that rare, why are they so expensive? | In addition to these correct answers, you may be interested to know that 84% of diamonds in the world move through the [Antwerp Diamond District].

Why does mentally handicapped people often look unattractive? | Part of the reason is that you are driven by nature to find other humans attractive if they meet certain criteria, even if you aren't consciously aware of the criteria.

How do countries like Russia or China block entire domain names? How (if possible) do people get around it? | In Russia there is a federal list of blocked domain names, and it's fed by court decisions mostly, although some bodies like the Russian DEA can put drug-related sites on it. The list is public in the sense that you cannot browse it but you can check any domain name or IP address and see who, when, and why banned it. A... |
How does Zero to the Power of Zero Equal One? 0^0 = 1 | 0^0 is mathematically undefined but many calculators and computer systems will evaluate it to be 1. This is probably because the exceptional case of 0^0 is rare and not worth implementing in hardware the way division by zero is. Software libraries that do power calculations may or may not detect the 0^0 exception, I ca... |
How come after a day of drinking I just want to go to sleep? | Alcohol makes you tired because it is an agonist of the GABA-A channel in the central nervous system. What this means is that alcohol binds to certain channels in the nervous system and increases the amount of time these channels stay open. This increases the amount of GABA signaling in the nervous system. GABA is an i... |
Are router speeds like 1300 mbps utterly useless if you're only getting say 80 down/20 up from the ISP? | They're still useful for file transfers between computers on the same network - for example, if you use a Plex or other DLNA server to stream to your TV. But it's useless for accessing the internet. |
Ubuntu. I'm ready to leave the Mac world, but not too interested in returning to Windows. | Ubuntu is pretty intuitive, it comes loaded with programs that will handle most/all of what casual computer users will use and it's free. Most Linux distros, including Ubuntu, have an option called a Live CD/USB. This allows you to burn a CD or set up a USB disc that you can boot off of which means if you already have ... |
Why don't we see game developers aim for anything between between 30 and 60 fps | Often console.games will float around between 30 and 45 fps but an fps that's changing is worse than a fixed one so they just lock the fps to the lowest common denominator |
Is the weightlessness felt from free fall while orbiting the earth the same as weightlessness felt during space travel, such as a trip to the moon or mars? | I'm not sure what you mean by 'the same.' You can be weightless in strong gravity or low gravity, so if that is the distinction you mean, then no. The ISS for instance, orbiting the earth, has, iirc, roughly 80% of the gravity we have on the surface of the Earth, but you're still 'weightless' inside due to free fall, a... |
Ronald Regan and his significance in politics today | Because it's easy to point to the past. We remember the past fondly, and don't remember all the bad stuff. Ronald Reagan, in today's political climate would be considered a moderate democrat or a VERY liberal republican.

Why don't airplanes use the same seatbelts as cars do? Or vice versa? | The two point safety belt in planes used to be the standard. The three point seat belt was made popular by Volvo in response to an executive's wife's head going through the windshield.

Does Mars (and any other planets for that matter) have plate tectonics like Earth? | Your main question has been answered, so I'll just add something else in response to your comment: > it would be crazy if stuff was moving about on Mars causing earthquakes and what not Plate tectonics aren't needed to cause earthquakes, see [this article on Moonquakes and Marsquakes], which can be triggered by gravita... |
Theoretically what would a person born with two Y chromosomes be like since a girl is XX and guy is XY? | The x chromosome carries a lot of important information beyond sex determination. It's unlikely, but possibly for a fertilized cell to have a YY or OY configuration, but those combinations would not result in a viable fetus.Reposting the best response from the same question asked a year ago in [another subreddit] Hope ... |
Why can't I take a full on clear picture of the night sky with all of its stars with my iPhone? | The sensor can't capture the light from such faint input in such a short amount of time.

if homosexuality is a genetic trait, why hasn't it died out? | Here's a funny example- sickle cell anemia can kill you, and is genetic. But if you only have one copy of the gene instead of two You end up more resistant to malaria. So there is both an advantage and disadvantage for a population to have that gene in large numbers. Genetics is rarely black and white. Genes affect man... |
How does turning on my WiFi help my maps on my phone find me even when I'm not connected to a network? | Everyone using this functionality submits data of network names and their location.

When a surgery is very long (over 12 hours) how do the surgeons and nurses rotate and how do they tell each other what has been done so far? | For the most part, there is no rotation. Many surgeons or nurses are in the room for the duration of the procedure. My mom is the head nurse for open heart surgery and a lot of times you go 8-10 hours standing without even a bathroom break. Most procedures don't take that long at this point, but once the procedure star... |
Why are fracking companies not responsible for damaged property that is directly related to their drilling? | ELI5: It's because they pay for good lawyers and lobbyists.

What exactly does a DIMM or SO-DIMM do in a computer? | That is the RAM for your computer, it's used to store all the running programs, so all the text on the screen, the source to the reddit website, and the images at the top are saved there.

Why was age 18 the decided age for adulthood? | It is an arbitrary number and not really supported by science or even uniform for lots of things. The age of 21 used to be the age of adulthood in most states. Again, that was kind of an arbitrary number. In the 1960s, the vast majority of states didn't allow someone to vote until they were 21. However, the school syst... |
Why is it that dogs and cats have clear signs of pleasure? | As others have said, it's a by-product of evolving along side humans.

I eat a healthy diet and get regular exercise, is the difference between eating white bread vs. whole grain even worth contemplating? | Whole grain is marginally better. General fitness it won't make much difference unless you're professionally competing. If white bread is stopping you from going to the Mars bars then I wouldn't worry about it.Whole Grain Wheat and White Wheat are almost the same. Multigrain Whole Grain is the improvement. With somethi... |
Why Assad is bad and should go? | [His dad] was a dictator over Syria for 30 years. People actually expected mini-Assad to be a reformist when he assumed power, but then he turned around and started committing war crimes, leading the UN to go ''Well, shit.'' He has imprisoned some 200,000 people, I believe, merely for speaking out against his regime, a... |
Why are bees dying at a alarming rate and how will it impact me and my life? | Colony Collapse Disease. Nasty business. Bees are responsible for pollination of almost all the orchards in the US.
