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.

Oh, interesting, I did not know that.

I mean to be fair 'scientists have lied about Venus atmosphere' is about as good of an idea as 'we should send space trash to Venus'...

Venerian or venusian, but definitely not venetian, unless you're talking about Venice.

"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.)

Reply to comment by BailysmmmCreamy in Are galaxies just giant accretion disks around super massive black holes? by darthvadercock
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.

Congrats on hitting the lottery in the Dad Draw.

And if you don't hit it properly, it can come back like an asteroid. An asteroid full of your own toxic wastes flying uncontrollable in the solar system, ready to hit earth again.

Would that not have a ripple effect, even if it takes billions of years?

Reply to comment by AlphaDrac in James Webb Space Telescope finds no atmosphere on Earth-like TRAPPIST-1 exoplanet by locus_towers
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.

For us, essentially nothing. Some stars extremely close to the galactic core might have their orbits disrupted, but we might not even notice.

Yea! That’s certainly how I understand it. I was curious how that fit into the black hole contributing little to holding the galaxy together as commented. Maybe it just plays a larger part in the early formation of the galaxy.

Reply to Hypothetical question by jd-sutton
From 100ly JWST would see Earth as a single pixel dot, if it could seperate it from the sun's glare at all.
Here's a planet 25ly away from the Hubble Space Telescope:

Reply to comment by Trinull in Hello everyone . I am very interested in space megastructure. such as mckendree cylinder or bishop rings. But suppose we built it. How can a spacecraft dock with it ? Knowing that these huge structures rotate at huge speeds to generate a gravitaty similar to Earth's by Dizzy_Ad3353
I could see a proboscis with a bunch of docking ports and a slip ring connection that cancels the rotation. Then you can dock more than 2 things.

I appreciate your thinking. The idea is appealing. I think we are already heading into that direction Universally speaking.

Tell us all repeatedly how you don't understand basic science and physics and all that fun stuff without admitting you don't understand basic science and physics and all that fun stuff.

Because we are so good at sharing and not oppressing each other. Morality is learned. They could be good lessons or bad ones. But World leaders don't give me much hope.
