The ISS has been pinholed by debris a few times. Likely paint. The shuttle was damaged by foam breaking off, amongst other events.

By comparison orbital velocity is around 7km/s, while a bullet is around 0.367km/s. Any mismatch will push debris up to bullet speeds easily.

As for relativistic speeds. C is 300,000km/s assuming you get up to 1/3C (barely relativistic) you are moving at 100,000km/s or 14,000x faster than the ISS moves, or 39000x faster than a bullet. A 10g rock would hit with 10kilotons of energy. About 2/3 the energy of the first atom. bombs.

It’s actually a legit concern with any (hypothetical) interstellar mission. Even hydrogen atoms will hit with significant force. Dust hits like nukes, and an asteroid is just game over.

The maxim used in a lot of sci-fi is an ablative armour plate. Often in the form of ice. Interstellar ships would likely aldo be needle like, to minimise their cross section. We could also use electric and/or magnetic fields to move smaller particles out of the way.

As for densities, I believe it’s a couple of hydrogen ions per m^3 . Dust is rarer, but still present. It’s only bigger rocks that are rare enough to just hope to avoid.

I fully agree that nuclear SHOULD have been part of the solution. I disagree that it should now be part of it. We have lost too much knowledge regarding nuclear power to lack of investment. We no longer have time to rebuild that to get it online. Hopefully it can become part of the solution eventually, but 10-20 years is now far too long to wait.

I agree with the mental bandwidth. I’m fine with he/him, she/her, they/them. I’ll also tend to default to appearance, though I will try and correct if asked to do so.

I’ve yet to find anyone who wasn’t also an arsehole who has an issue with this. That includes places where seeing an obvious male in a dress could equally be someone taking their first steps away from norm, or just a guy that likes wearing dresses. Also, neither was seen as unusual at the event.

I help with a social group. We jokingly refer to it as anarchism under a lazy iron fist.

Day to day decisions are made in a fairly ad-hoc manner, by those involved. If there is a disagreement that can’t be resolved, or if it will have large repercussions (e.g. changing the fabric of the building) it gets raised to the committee and chairman.

The chairman is the sort who is only there because no one better wanted the role. He has no interest in micromanaging, but will resolve issues to get them to go away.

It’s a remarkably effective system. Unfortunately it’s a bit unstable in large groups. Those who want the role are also those you REALLY don’t want with that power. No one has yet solved the issue however. How the f@#£ do you keep the troublemakers out, when they are also the ones most willing to work towards getting the role?

The other problem with anarchism is that the natural self policing systems break down by the Dunbar limit. Parasitical or cancerous behaviours tend to become crippling, forcing people to adopt other unofficial power structures.

Orbits are all about speed, not height. To deorbit, you need to reduce your speed at the highest part of your orbit. This will lower the lowest part. You jump off the back. You would need to jump FAR harder than your legs are capable of though.

Unfortunately, the sheer speed will kill you, without shielding. As you hit the air, you are going so fast, the air can’t get out of your way. You compress it ahead of you, that heats it up. It gets hot enough to melt most metals. The air will cook you, long before you get slow enough to use your parachute.

For comparison, terminal velocity (max speed you reach falling) is around 200km/h. Orbital velocity is 7km/s or around 25200km/h.

The glue gets weaker when it’s heated. They use the same film for oven meals as well. It comes off fine when you finished heating, but it’s a pain in the arse when cold.
