Wouldn’t the proton and the antineutron remain far enough away to avoid their component antiquarks from annihilating?

Oh so that’s why the urine in the toilet turns more yellow the longer I pee.

Its exact role in the immune system is unknown and it doesn’t seem absolutely necessary, similar to how people who are heterozygous for sickle cell anemia do not display symptoms because they have sufficient amounts of normal blood cells even if some of their blood cells are sickle cells.

It seems they want to use steam for some reason.

It doesn’t scale down well. 1 solar panel can generate power, but for the CSP it needs a very large central heat engine and lots of mirrors surrounding it to focus light at the center.
It’s also very water intensive, which is seen as a waste because it needs to be put in places with a lot of sun, which tend to be dry and water scarce.

That’s called concentrated solar power, and it uses a lot of mirrors to focus the sun’s heat onto a bunch of salt to melt it down and use it to generate electricity.
Apparently its efficiency is similar to that of solar panels. But it should be cheaper since you don’t need expensive materials for all the solar panels, only normal mirrors.

Huh, I thought acceleration was so similar to gravity as to be virtually indistinguishable.

It would help to a certain extent. In water, the acceleration force would translate directly to pressure such that if you accelerate at 1g you would feel the same amount of pressure as you would underwater on Earth.
So assuming you’re under a meter of water onboard the ship, you could easily go up to an acceleration of 40g since then the 1 meter depth would be equivalent to being at 40 meter depth on Earth which is an okay diving depth for recreational divers.

Reply to comment by Peasant_hacking in Insects get stuck in a spider's web, why doesn't a spider get stuck in its own web? by Koning_Health
Yes, the radiating lines are non-sticky while the circling lines are sticky.
Also when wrapping their prey they manipulate the sticky web with their claws which are coated with an anti-stick substance.
If you were to grab a spider and just slap it directly flat onto its own web it would probably get stuck.

Maybe it would’ve been too late to stop the growth by the time he was 6’1”.

Reply to comment by Ramast in Do house flies molt? by Ramast
This applies to nearly all insects too. When an insect is unable to molt any more, then it usually means it’ll die soon since they can only really regenerate their organs when they molt. It’s why arachnids and crustaceans can live so much longer than most insects, because they can keep molting and hence rejuvenate themselves.
When insects injure their exoskeleton, the most they can do is exude a patchwork fix. When spiders and crustaceans lose an entire leg, they can regenerate it after a molt or two. The most primitive insects like silverfish have no metamorphosis and can keep molting as well.
It’s telling that the longest lived insects, termite queens, are protected by an entire colony and do not need to move around, minimizing the damage they sustain.
