I read a really depressing article on IFL science about a study that predicted a 90% chance of global societal collapse in the next 20 years.


Awesome.


But the question that gets me is say some aliens visited 1,000 years hence, what would they find?


In particular, would all of our space junk and satellites have decayed and burned up?


I figure modern architecture is pretty fragile and unlikely to stand the test of time. The pyramids will still be there, of course, and maybe some other stone structures. Angkor Wat would have been reclaimed by the jungle. But would there be any sense that our technology was an advanced one, or would all the signs of that have disappeared?
