Reply to comment by ArcadeAndrew115 in ELI5: How do we know for certain that atoms can't have more than 8 maximum outermost electrons when atoms form chemical bonds? Is there any research being done to see why atoms prefer the octet rule? by ArcadeAndrew115
There are always exceptions. For every rule there is some weird circumstance or extreme condition that breaks it. Our rules are constructed out of convenience because they fit basic circumstances and help us to learn.
When teaching chemistry we tend to teach a bunch of rules and then later teach the exceptions, because it's easier to understand the exceptions after you have the necessary base of knowledge.

Reply to Why are green and red laser pointers so cheap and available, but yellow ones not so much? by SurprisedPotato
Infrared and red laser pointers are direct laser diodes (put current in and light squirts out). Green and blue laser pointers are made by using an infrared laser diode to pump a nonlinear optical crystal which doubles the frequency (halves the wavelength... however you want to say it) to put out photons with a new color. That doubling leaves a gap of wavelengths that are more difficult to access.

Reply to ELI5: How does a beer bottle top stop the gas in the bottle from escaping enough for it to remain fizzy for extremely long times? by trumps_baggy_gloves
It absolutely can and does create a seal strong enough to keep the gas contained. Note the inside of the bottle cap, it has a rubber gasket which is pressed against the lip of the bottle mouth to create a seal. Furthermore, this seal doesn't have to resist as much pressure as you might think, most of the carbon dioxide is dissolved in the liquid, the cap only has to contain the pressure in the small head space enough to shift the equilibrium toward dissolved CO2 over gaseous. Same as with soda bottles.

That description literally makes me feel sick r/tihi ... To be clear, I have no doubt that it is metaphorically accurate but I'm not sure I could stomach the results if I were to Google it

Almost certainly yes, heat dissipation is a huge problem in space/space travel.

If you yell in space the energy goes into the gases that you are expelling as heat. If you tap a tuning fork in space the energy pretty much stays in the tuning fork as heat until it can be radiated away as infrared.

Reply to comment by Mammoth-Mud-9609 in ELI5 why do onions burn your eyes when cutting them? by [deleted]
It's their revenge on you for cutting them. But seriously, it's meant to deter things from eating them. Which of course is one reason we (as humans) eat them, because humans are weird and we sometimes like pain. Kinda like hot peppers, they got spicy to discourage anyone but birds (who can't taste spiciness, and are the best seed spreaders) from eating them. But that kinda backfired in the case of us weirdo humans.

Reply to comment by kormer in Chewy to close large central Pa. fulfillment center by vasquca1
It's not just one of the oldest, it was THE Very First Chewy warehouse. It was in a dire state of decay and I'm honestly surprised they let it limp along as long as they did. It was originally a tank factory, then an ice cream factory, then Chewy bought it. The building has run its course. The Lewisberry facility is awesome and will be absorbing any of the workforce who wish to transfer, nobody will be laid off or demoted.
