Reply to ELI5: if Earth rotates so fast, why does it always look still from outer space? by ShesOver9k
OK, what about the fact that earth is orbiting the sun at 67,000mph? How is it possible to see the earth from space if earth is constantly moving that fast and there's no way a space station or satellite can move that fast with earth and follow it?

All available evidence indicates that those fears are entirely unfounded. Being skeptical of GMOs is the same as saying vaccines cause autism, it's simply anti-science

MSG does cause some people to get migraines. Also makes my ankles swell and makes my stomach upset the next day!!

It'd probably be more intuitive to call it "stellar spray".
"Wind" implies that there's already a medium hanging around, and "wind" is just what we call it when it starts to move around. That's not really what's going on. There is no medium quite like that in space (I mean, technically there is, but the absolutely miniscule amounts of it is not what stellar winds are made of).
What stars (like the sun) are doing is basically sneezing particles outward in all directions at all times. Like when you see a person sneeze in just the right light and you see the spray of droplets fly out into the air. There is a kind of flow to it, like wind currents, but it's not a flow of stuff that was already there, it's a cascade of stuff being ejected out from a source.

Reply to comment by WeDriftEternal in ELI5: Why was Berlin split into two when it was so far into Soviet Territory? by gorginhanson
Note that Vienna was also parted into four sectors. Austria however regained independence as a single country in 1955, before the Eastern bloc started their wall-building frenzy.

Oh I see the point. Thanks, it now make sense.
Medicine deals with averages is super interesting concept I haven't thought about before.

Reply to comment by HunterIV4 in eli5 What came of Edward Snowden leaking all of that classified intel? by tpb772000
True but imo the main problem is we haven’t figured out proper legal structures for data rights, and I think GDPR is positive step. Plus it inspired the California law which I also consider a positive, albeit tiny, step forward

Reply to comment by Latin_For_King in eli5 What came of Edward Snowden leaking all of that classified intel? by tpb772000
I agree it was the right thing to do to expose the leaks, I just don’t buy that he didn’t want to go to Russia or China in the first place. Also at this point he’s basically helping the kremlin, tweeting all day about how evil the US is while not saying a peep about what’s going on over there.
Obviously he’s probably not free to say what he thinks, but still I don’t buy his story that he just HAD to go to Russia and nowhere else. A lot of places don’t have extradition to the US and aren’t autocratic mafia states with no civil rights

Space is not a perfect vacuum, in terms of having no matter present whatsoever. It's a strong vacuum, in that is has much much lower pressure than on Earth (where we have a lot of very dense atmosphere causing that pressure).
Different areas of space have some amount of matter, with different amounts and kinds of matter in different kinds of environments. Stars, like our Sun, generally have winds of plasma that is, in a vague sense, boiling off of the star and flying off into space (at hundreds of kilometers per second!). Interstellar space (areas between stars) also has matter throughout: a combination of gas, plasma, and dust, but all very thin. This interstellar medium (ISM) is actually my research specialty as an astronomer. The typical density of the matter in the ISM is something like 1 particle (an atom, molecule, ion, or free-floating electron) per cubic centimeter. For comparison, Earth's atmosphere is roughly 10^(19) (10 billion billion) particles per cubic centimeter. So the ISM is 10 billion billion times less dense than the air we're used to!
All this ISM stuff is moving around. It's orbiting around the galaxy (just like all the stars), and it's mixing around because of turbulence and other effects. And even though it's all so thin, there's still a lot of variation between different locations: there's hot regions (1 million degrees!) with low density plasma, warm regions ("only" 6000-10000 Kelvin/Celsius) that can be gas atoms or plasma (or a mixture), and cold regions (less than 100 Kelvin or -200 Celsius) with gas molecules. So you can get all kind of complicated and interesting interactions, like hot gas crashing into clouds of cold gas, or blast fronts from old supernova explosions plowing through areas of warm gas (making it hotter and more compressed).

Reply to ELI5: How do plants know that they will be eaten and therefore their seeds will be spread and regrow? by HazeThere
It was accidental evolution. Millions of different fruits evolved with different tastes, but some happened to be sweet.
The sweet ones were able to outcompete the non-sweet fruits because more animals ate the sweet ones, spreading their seeds.
This gave them a huge advantage in reproduction and eventually they became the more dominant fruit tree, and the fact that animals enjoyed them meant they would not die out.

Reply to ELI5: Newton's third law by AppropriateFeeling44
When object A acts on object B, object B also acts on object A, but on the opposite way.
For example, picture a cat sitting on the floor.
The earth is pulling the cat down through gravity, but the cat is also pulling the earth up through its gravity.
These forces are opposite but equal to each other.

Mining engineer here,
Mining was the single most dangerous job in the world till about 1950. Old mines would use the change in temperatures combined with tunnels designed to encourage natural ventilation. A fire could be started that would "draw in air" and a smoke shaft would be built.
In 2022 we use 2000 hp fans to keep things cool/ clean air. Some extremely deep mines I have been to legit use the largest air-conditioning system the world has to keep the temp at a cool 120F its so hot 5000ft underground
Look at this graph of deaths each year in USA mining

Can't be explained more thoroughly than that. TL;DR = cause it's a useful "spice" and racism.

Stellar winds are jets of charged particles from the star. They're the same as Solar winds, it's just that "stellar" is the generic term whereas solar is only the sun.
They're not winds as in the movement of air. We call them that because they move in ways analogous to wind.
