Why is there so much opposition to universal healthcare in the US from even people of modest income who would benefit substantially from such a policy?
[ "It would cost a lot of money. That money would have to come from taxpayers. Folks with modest income don't expect Government to start taxing the rich exclusively, given their political power.

As a passenger, why do my ears feel like exploding when 1 car window is rolled down?
[ "You're forcing air into a confined space with no good way of escaping. This increases the air pressure. The only way for it to escape is out the way it came, which eventually it does do once enough pressure inside the car is great enough. As the air inside the cabin leaves out the window, pressure reduces to the p...

What is happening when our head is "spinning" after drinking too much alcohol
[ "It's called positional alcohol nystagmus. Basically, there are these things in your ears called semicircular canals that are responsible for your sense of balance.

Why is the speed of light (c) squared in the equation 'E=mc2'? Or velocity (v) in Ek=0.5mv2?

What is the relationship/correlation(?) between the moon and the tides?
[ "The rotation of the moon around the earth causes the tides.

Do atomic nucleï rotate if the molecule they are in rotates?
[ "If you rotate a molecule the nuclear spins of the atoms will not rotate with it, as there's no simple interaction that rigidly couples the nuclear spins to, e.g., the orientation of bonds, and so angular momentum must be conserved.

This is really hard for me to word right. We only know the "observable universe" because light passed the 13.8 billion LY mark hasn't reached us yet. Is there new light showing up all the time?
[ "Yes. Here's the harder question: if at some point the expansion of space counteracts the growing of the observable universe, will we reach a critical point that is the maximum theoretical size of any given \"known\" universe?" ]
[ "Yes, but things expanded away too fast for their light to reach us." ]
What does it mean to plea “no contest?”
[ "Basically it means, \"I'm not pleading guilty, but I can't or won't fight the charges.\" Functionally, the court operates as if the defendant plead guilty, but the plea can not be used against them in any future proceedings; for example, if you plead guilty to a traffic violation that caused an accident, that guil...

Why does bottled water taste differently from one brand to another?
[ "It isn't just water, there are trace minerals added to affect taste." ]

Why is deuterium six times more abundant in the Earth than in Jupiter and the rest of the universe?
[ "It is not so much that deuterium is more abundant on earth...it's that regular hydrogen, or protium, is less abundant. Protium is light enough that it readily evaporates out of the upper atmosphere and escapes into outer space. Deuterium is twice as heavy...that is still light enough to escape, just not quite as r...
[ "sugar is heavier than water but if you mixed it into water it will distribute throughout. If sulfur hexafluoride forms a solution with nitrogen and oxygen it will be distributed throughout the atmosphere. Winds could potentially mix heavy gases and distribute them over large areas." ]
How do ambulance services work and why do they cost money?
[ "911 will radio to ambulances and those that are capable of responding (not busy, close enough) will let 911 know. This is similar to how tow trucks are dispatched. People in the US usually have to pay for ambulances because, unlike fire or police, the ambulances are not part of the government. They need revenue to...

How can three-wheeled vehicles such as Spyders be accredited as road-safe when 3-wheeled ATVs were discontinued for safety concerns?
[ "Because a Spyder has different weight distribution that creates a low center of gravity and makes it considerably more stable, and Spyders (and the other similar 3-wheeled vehicles) are not designed for \"all terrain\" (ie, off-road, on rough ground, rocks, deep mud, etc) use, they're designed for highway use on p...

Is Netflix perceived as the 'good guy' in the whole Net Neutrality shebang?

How does your body know to wake up after sleep?
[ "Without going into the mechanisms of how your brain works, the most I can say is this. If your brain is a battery that empties during the day, then when it's fully charged after sleep, you know to wake up. There are other things that can wake you up, such as sounds, movement and, most often, light." ]
[ "It's because the colour receptor cones in your eyes wear out relatively quickly when they're looking at the same colour for prolonged periods, causing you to see less of that colour when you look to see something else.

can small things see smaller things that we can’t see with our naked eye because they’re smaller?
[ "Small eyes have fewer number of sensory cells, so the resolution of the image they produce is far worse. Ants probably can't see microscopic organisms, but they can see what's relatively similar to their own size." ]
[ "That's mostly a question of size. A radio antenna is designed for radiowaves. Shrink it down to nano size, and you'll end up with a nano-antenna for visible light." ]
What happened to people in jail during the Great Depression? If the public could barely afford to live how could prisoners? Did any of them die from starvation or were they all adequately fed?

Do we lose any weight through exhalation?
[ "You're exactly right! We actually lose *most* of our weight through exhalation. (Sweating is the other major mechanism, but since that's mostly water it doesn't create a net loss.) This is why weight loss is so hard; all the fat molecules that your body stores have to be oxidized and exhaled." ]

Why do we refrigerate the bottles of coffee creamer and not the small little disposable ones you find at gas stations or 7/11?
[ "Those small ones are sterilised, like sterilised milk that you can find in a carton that does not require refrigeration until it's opened. Not sure all creamer requires refrigeration, but it's probably down to it's contents, some might break down once opened as it's exposed to oxygen." ]

Is it possible for a star to have a low mass yet have a large volume?
[ "Yes, that's pretty much what red giants are. They have masses ranging from 0.3 to 8 solar masses, but their radius can be up to 200 times larger than the Sun. Red supergiants and hypergiants are even larger, but also more massive." ]
[ "It's easier to break up the clumps when there is less room for the clumps to slip away from you.

When tehre is less water, simple stirring will cause th...
Why did Boeing workers in S.C. just overwhelmingly vote against unionizing?
[ "Unions have *sometimes* improved conditions. However, they've also made them worse - they're not a universal panacea to all problems. Boeing workers generally make $20/hour or more, with full benefits. Their work environment is safe and (relatively) pleasant. So the workers have very little incentive to submit to ...

Neurologically speaking, what makes a child's brain better at learning new skills and languages than that of an adult?
[ "Lack of myeline around axons makes new synapsis easier to form, and our cerebral axons get myeline coats from age 25 or so onwards.

What are computer glitches and why do they occur?

Why are baseball teams so inconsistent year-over-year compared to basketball teams and those of other sports?
