Can we make a black hole? And if we could, what could we do with it?
Also a great (short) one by Kurtzgesagt

A Dyson sphere around a black hole
Kurtzgesagt made a video explaining some possibilities. In short, you can throw mass or radiation at a spinning black hole and "steal" rotational energy from it.
⬐ chiialso, you can use light, instead of matter.Termed the "halo drive", it's a very nice theoretical concept: https://www.youtube.com/watch?v=rFqL9CkNxXw

What if Planet 9 is a Primordial Black Hole? (2019)
There's also the Penrose process which is theoretically useful on spinning black holes. I also watched this in the past, which has some fun ideas (that are probably a little fanciful?) https://m.youtube.com/watch?v=ulCdoCfw-bY tl;dw: put a mirror around it and shine light in, get back lots of energy and/or blow up your whole solar system.I'm not sure if any of that would apply to a ~planet mass black hole spinning with ~planet sized angular momentum, or how solid the physics even is, but it sounds cool anyway.
⬐ rbanffy> get back lots of energy and/or blow up your whole solar system.Fun concept - a bomb you can't throw without it dragging your world along.

Saudi Arabia threatens to ditch dollar oil trades to stop 'NOPEC'
I used to play with an idea of a science fiction novel, where the united Earth's currency is essentially kcal/kJ. The problem is that if you have a flammable and radioactive material, do you count the energy you get from it by burning it, or the energy from throwing it into a nuclear fission reactor, or the energy of throwing it into a black hole in a particular angle[1]?

What life could be like for civilizations 1 trillion years from now
Kurzgesagt had some nice summaries of: 1) Why white dwarves might be the last home for life in the universe - https://www.youtube.com/watch?v=qsN1LglrX9s 2) ...or maybe it will be black holes - https://www.youtube.com/watch?v=ulCdoCfw-bY

⬐ tomrodI really enjoy Kurzgesagt's videos. I believe this one is particularly well done, and look forward to learning more about the concept of "ringularities."
