Why does America (or any country) have a fiscal deficit?	[ "Actually it pretty much is simply to avoid inflation. Assuming you know how inflation works, look at what happened in Germany after WWI.

what is the time frame for the negative impacts of climate change if we don't change anything?	[ "I should start off by saying that, despite how politicized climate change has become (especially in the US), it is, in actual fact, a verifiable phenomenon that we are almost certainly causing.\n\n\nGoing by the recently-released [US National Climate Assessment](_URL_0_), climate change has effectively already beg...

Why don't people seeking physician-assisted suicide just overdose on their regularly prescribed pain medication?	[ "I think you're missing the point. Any one can kill themselves any number of ways.

What were the evolutionary benefits (if any) to humans enjoying certain "music" or having some sounds appeal to them.

Why the OJ Simpson case was such a big deal?	[ "It was a big deal because it was obvious that he murdered his wife and his wife's friend. Anyone who followed the trial could see that fact clearly.

Why the population of Bangladesh, Pakistan, India and China so high compared to other nataions in this world	[ "Rice, rice, baby.\n\nOf grains available to the pre-industrial world, rice yields the most calories per acre of land.

[ "From Google:\n\nAlcohol, especially in high concentrations, will irritate the oral mucosa (we don’t like saying it as much as you don’t like reading it, but it’s just the mucous membrane lining the inside of your mouth). That irritation can come across as a burning sensation, the same kind of thing that happens wi...
How much advertising actually helps. If a big name company (let's say Coca Cola) was somehow forgotten by everyone overnight, how long would it take to return to its current level of success (with its current advertising budget)?	[ "Since we're speculating here, I'd imagine it'd be between 5-10 years (given its current advertising budget). \n\nHowever, with the mound of cash they're sitting on, their best course of action would be to flood every outlet with their name (spending what I'd imagine would be 10x their current budget) so that all w...
does plugging my ears with earplugs do any damage to my ears?	[ "No, soft foam earplugs can cause no damage unless you leave them in for days at a time or somehow manage to stick them in far enough to hit your eardrum. This should be next to impossible though." ]

why is pointing at something considered rude?

to someone who doesnt live in America BlackFriday? is it really that good?	[ "Black Friday is the way the American population \"kicks off\" their Holiday shopping season.

Why do some companies copyright strike Youtubers for putting their logo/product/song in their videos?	[ "That's not how copyright works.

why does it take so many writers to write pop music?	[ "Pop music is science not art. It requires architects, not artists. All the pieces have to come together to make it appeal to the most people.

How do modders optimize games that are badly ported?	[ "There are several ways. The easiest is probably to just twiddle with the config files until the game runs better. More complicated issues, such as framerate limits that normally can't be disabled, can sometimes be fixed by editing some parts of the game's executable file or other binary files with an hex editor.\n...
How does space-time dilation work?	[ "I forget what redditor explained it this way to me, but this is the best way I can describe it:\n\nThink of space and time being orthogonal.

Why it's not possible to clone encrypted contactless smart cards?	[ "With a smart card, you're not actually reading the card. You're having it do something for you using a secret key that cannot be read off it." ]
What is it about computers that allow us to double the speed every 18 months or so. Does this occur\has this ever occured for other technologies? And if not, why not?	[ "This is due primarily to improvements described by [Moore's Law](_URL_0_). It was originally an observation.

Why do planes shake when going through clouds?	[ "Usually it's cumuliform (puffy) clouds that do this. While enough moisture in the air will cause clouds to form, any source of lifting will cause these clouds to fluff up. That air movement will, obviously, also effect the airplane and push it around. It's basically the same as turbulence you get in clear air. ...
Why do we find stuff "oddly satisfying?"	[ "The human brain responds to and rewards you for identifying patterns. An example of this is music, where your brain rewards you (via dopamine and other feel-good chemicals) for predicting and identifying patterns of notes.

Sometimes when media posts photos of people that are in a coma, had a severe traumatic brain injury, or have mental impairments - you can somehow tell from their facial features. How is that possible, and what facial changes causes this?	[ "My non-medical opinion is facial muscle tone.

Your face will be lax." ]
Why it takes so long for NASA to prepare one launch	[ "cuz it's a machine going into fucking space", "They have to make sure everything is working perfectly, because if it isn't, things can go horribly wrong.

Why do you get extremely hot right before freezing to death?	[ "When you are cold, the blood vessels near the surface of your body constrict, reducing the amount of warm blood exposed to the cold and limiting heat loss.

Why do Macs seem to run games way worse than PC even if they aren't games with crazy graphics?	[ "I don't know if this is necessarily true. I could see this being true if a DirectX Windows games is ported to Mac using OpenGL, and the port isn't done well. What specifically have you experienced?", "Optimizations.

What exactly is Effective Demand?	[ "There was no mention of a constrained market in Econ 101, because it's a complicated concept; this is why you should ignore everyone who tells you that they know what economic policies we should have because they took Econ 101.\n\nAnyway. Suppose that I want buy a smoothie every time I go to work out. My demand ...
How does externally applied "fat burning" gels work?	[ "This is just a hunch, but they just do not work. The only way to lose fat is to consume less calories than you burn through out the day. So you can eat the same but exercise more, consume less calories and don't exercise any more/less or a combination of eating less calories and exercising more. It really is that ...
Why does fresh cut grass smell so potent?	[ "Because it's traumatized! \n\nGrass (and many plants) release chemicals when they are cut or injured that do a few things.

Why do I see a shadow on the inside of my eye when I push my finger on the outside edge of my eye?	[ "Your finger pushes against your eye and distorts the lens that focuses light on the back of your eye. A small indentation can create a black spot where light doesn't focus, or focuses very poorly. It's similar to how you can have dark spots on the bottom of a pool by distorting the surface." ]
Why does only one nostril clog up with mucus when I'm sick?	[ "Surprisingly, about 80% of people breathe out of one nostril at a time, alternating about every 2.5 hours.

We might have a decent understanding ...
What actually happens when a computer game crashes?	[ "So, I'm not a game developer but I am a software engineer.

How do sharp angles on a vehicle affect a radars ability to detect it, such as the USS Zumwalt	[ "I think a [picture is worth a thousand words](_URL_0_) in this case. I find it hard to describe what's going on without a visual aid.\n\nWith a curved surface, the radar hits and spreads out.

Why do cameras have a maximum SD card capacity?	[ "Digital cameras basically run an OS much like a computer. If the kernel, or BIOS, was limited to addressing a maximum size of 64 GB on a storage device, that's simply all it can see.\n\nI should note that it doesn't mean there's anything nefarious going on, necessarily, it's just a limit of the architecture they'r...
Since gender is considered fluid rather than binary, what is the point of sexual reassignment surgery and how is it considered more than cosmetic?

How come airlines are able to stream live satellite TV to their entertainment systems, but have trouble providing stable on-board internet access/Wifi?	[ "Beaming TV to the plane is a one way connection. WiFi and Internet require asking for data and waiting for the requested data to arrive, then asking for more.

Why do TV actors earn residuals upon re-airing for their performances, but recording artists don't earn a dime when their music is played on the radio?

How do CD's work?	[ "A CD stores information in binary. I won't go into how binary works, but the short version is simply that it used 0 and 1 to store information.

Why do spins/jumps in sports continuously get more intense?	[ "It's primarily two things:\n\n1. Better equipment. Technology plays a larger role in these things than most people realize. Simply the fact that modern equipment is lighter, stronger, has more flex, rebound and spring allows athletes to do things that were literally impossible 20 years ago.\n\n2. Athletes start tr...
What causes free WiFi hotspots at hotels etc to be so patchy and unreliable.	[ "Setting up a wifi mesh is expensive, and frankly not worth the effort and cost for many small motels.

Large ones may have a mesh, but i...
why does our eyesight weaken?	[ "A good understanding of vision loss requires a brief foray into the basic structure of the eye.

Why does the moon cause waves in the ocean but not on smaller bodies of water like lakes?	[ "Firstly, the other responses suggesting that tides are not waves are incorrect - tides are waves, they just have a very long wavelength (and are not related to the smaller, wind-driven waves that we colloquially call 'waves').\n\nTo actually answer the question, it's because lakes are generally too small for the...
Why does the value of currencies fluctuate?	[ "The fluctuations are a result of supply and demand for that currency. For example, let's say there's suddenly huge global demand for American widgets.

Why does music seem to require so much specialized knowledge and adherence to rules for a person to create it, whereas visual art is something anyone can jump into intuitively (not master it, but at least create something potentially appealing).	[ "A number of things:\n\n1) Recording - the visual arts are readily recorded (the paper itself). However audio is less easily recorded. Yes, everyone has a mic on their smartphone, but its terrible.

My cat goes wild in the presence of bleach. Why is this?	[ "Well, shit, it sounds like she's getting some kind of chemical high.

Why Americans are more conservative and religious than Europeans ?	[ "Well, I think it's just that Americans are louder and hence given more coverage.
