Nobody should be preventing you from running around with a good stick!
By the time they’re going fast enough, they’re high enough they don’t have much air to worry about. (And they do have an angle over too, not just straight up)
Missiles do go more or less go straight though the atmosphere horizontally. Most are slower than what we’re taking about, but hypersonic missiles get close to rocket speeds. And they do need big heat shields to keep from melting immediately.
You’re going much too fast to hit the earth, you’ll miss it and continue in orbit. To deorbit, you’ll need a lot of things to throw in the other direction, like the oxygen from your magic tank. You’d need about a full rocket full of oxygen (~170 tons) to slow down, probably more because the exit velocity would be slower than a rocket.
The other issue with this scheme is you’d slow down too slowly. You’ll start getting slower and lower, but you’d start to get into the atmosphere, which because you’re still going so fast would cause you to not have a great time. So your magic oxygen bottle will also need a massive tube off the end of it, maybe a couple meters in diameter.
But if you had your magic infinite air tank with a huge tube off it, theoretically you could get back down to earth safely with just it, a space suit, and a parachute.
It’s never going to be all knowledge, since a lot of stuff is just lost or never recorded. A ton of stuff (like this thread) are probably low on the priority list for recording as well. But the closest you’d probably get to a full catalog of human knowledge (at last text based) are the huge data sets of nearly all text data on the internet used for training LLMs. I wouldn’t be surprised if there are ones soon that include video and pictures as well, since newer AI models are starting to be able to interpret those too.
I believe this is one of those data sets: https://github.com/yaodongC/awesome-instruction-dataset
Edit: here’s a big data set used for a lot of gpt3 https://commoncrawl.org/
Some oppressors (indirectly, but essentially) started drawing lines one day and agreed that they would each get to farm the humans in their own territory.
Control goes back further than just territories to tribes. The tribe identity is only later tied to specific locations. Tribes formed because pooling resources burdens and learning was more efficient than doing it all yourself. From there, the tribes expanded and joined together and eventually settled into one location. So I disagree that oppressors just decided one day.
Widor Toccata! I love it when the pedal comes back in, always makes me smile.

Sorry for the very different style
