Nuclear rockets won't "ignite" until they're in a nuclear safe orbit, and it will be on a escape trajectory away from Earth. And a large rocket as you propose likely won't be able to have any prolonged operation in LEO, it would be above where the majority of debris is.

All of this ignores the simple fact that this isn't a video game, you don't just drive around picking up trash. You can use it to send trash away once you collect it, but it's not even remotely a good proposal on how to collect it.

"Unless"... Hey nobody tell him, just let him see it...

(Hahah joking, but yea. If we send our trash to another planet for 100 years, and then 1000 years, and then 5,000 years... How much mass will we have lost? We will literally be using all our resources to... throw our resources away. We will have to then start using more resources to capture asteroids for metal. The metal was already there, we just sent it away out of temporary convenience.)

I lean towards the "seed" idea, because black hole formation and growth as we understand it requires that supermassive black holes had to form already extremely massive relative to an 'ordinary' black hole.

A sufficiently energetic collapse to cause a supermassive black hole straight out is extremely unlikely to occur if things are already in any kind of orbit.

We still don't really know, but it's pretty interesting nonetheless.

While usually true, in this case they used MIRI to measure the amount of missing heat when the planet was behind the star as opposed to next to it. A secondary eclipse instead of a transit. They can then make assumptions about the atmosphere with that measured temperature and the fact that it is a tidally locked planet.
