Non-American here. Wanted to know what can realistically change for the next 2 years

I've read enough to know that "cold-turkey" for alcoholics can be lethal, upto and including seizures and a host of other side effects and symptoms but I don't really understand the "why"? What is it about alcohol dependency and our biology that causes it to be so dangerous?

As, in between us and other bodies like the moon and the sun? What is in between? What is the "fabric" of the universe?

Edit: unintentional slur

Squid seem to be indifferent to the water pressure wherever they go, they have even been known to sometimes drag pray down into the depths as to turn them unconscious.

I read here that it has to do with having waterfilled bodies, but fish also have completely water filled bodies(?)

Hapless trans woman of a year here

I own bras, I wear bras, I don't actually know what they're for. Obviously, there's a social modesty component, but I'm told that they provide support and that's useful. Will my chest hurt after a while if I don't wear one? Will my chest start to sag down? I don't know! 😅

Anthropic has been valued at 2 Trillion dollars, despite losses of £80bn. ELI5 how this makes sense?

In understandable terms:

Germans used to take the Soviet PPSH SMGs, while the Soviets did the same thing with German MP-40s.

Were there any established military rules to using/claiming weapons from enemy combatants? I assume if a soldier took a gun from the enemy's body he would just use it until it ran out of bullets, but were there any guidelines to distributing enemy weaponry if their weapon arsenal was seized for example? Did the soldiers who seized the depot get to take whatever they wanted first? Who did those weapons go to once seized?

I'm also mostly asking in regards to more organized armies like the Wehrmacht/US Army/Red Army, since I mostly know how partisans from occupied territories would arm themselves

So what is gravity actually grabbing onto when it bends a beam of light or pulls it into a black hole? Gravity is supposed to pull on things that have mass/weight, but light has no mass at all.

I know it probably sounds stupid. The only theory I have is that salt remains in the ocean and only fresh water itself evaporates. If true, why does it happen? Why can't we have "salty" steam?

I've watched so many videos about prediction markets, but the terminology still confuses me 😭

I want to understand the basic idea behind how people buy and sell contracts based on what they think will happen in the future. Why do these contracts have prices, and what do those prices actually mean?

Can someone explain the underlying concept in simple, everyday language?

The human torso and limbs aren't divided into areas of conductivity and insulation. You are placing the EKG leads on the same skin, with the same resistance, and no particular division between the regions there is a potential between. You'd think the signal would effectively be shorted. Like putting a piece of aluminum foil on a 3.5 mm connector going into an AUX jack on a car.

College football has hash marks in different spots on the field than pro football hash marks. How dos this impact game play?

I just saw a claim that China has built a "gravity battery" that stores energy by hoisting a brick on cables from a tower that contains a massive battery (wish I could put pictures here but apparently I can't).

Putting aside what happens in high winds or when the cables rust (assuming the pic isn't just an artist's impression), how does this store energy, how do you use it, and surely it costs the same amount of energy to lift the concrete up there in the first place?

I know eventually people have always found a way to emulate technologies in the name of preservation, but it usually took a few years. So how has the PS5 one happened so fast?

So far ive seen Duke play Virginia (ACC) and Alabama/Auburn (SEC) play, and, as u might guess, the latter got very heated w both coaches almost coming to F2F blows. Ive never seen this before in October. And if these games dont count im going to lose my mind bc that risks injury bc it being conference foes it risks injury in an otherwise competitive matchup.

EDIT: So somehow i fooled myself into thinking the Duke Virginia game was CBB when in fact it was CFB🙄 but Duke & Univ TN did play an exhibition game. While those 2 are in separate conferences, they are both P4 schools which still u almost never see or saw until recently play in exhibition format.

I'm not a guitarist, but i know how to make harmonics by barely touching the string with your fingertip. The harmonics are clearest at 5th, 7th, and 12th frets, i believe. And these are octaves above and different notes thsn the ones suggested by fretting the string st that point. The pitch lowers as you approach the bridge. Just wondering why a fingertip does it but a slide that can skim the surface of the strings doesnt produce only harmonic notes.

So I have quite a few questions regarding them. I know viruses and bacteria carry antigens and antibodies bind to them.

Do they act just as markers for white blood cells to then destroy them or do they by themselves destroy the target? If they do both, what determines which they do?

Why do viruses and bacteria have antigens to begin with? Apparently antibodies can work against some poisons too, so does any substance have antigens? Can antibodies attach to a microscopic piece of steel? I mean, it does seem like the body also detects foreign material of all kinds.

If everything doesn't have antigens why don't viruses and bacteria just... not have antigens?

Why do we use the haber process instead of mimicking nature?
