A researcher suggests that the “techno signature” of the trash might be a discarded reflective surface, rotating:

If only a few hundred mirrors were present, a much smaller telescope could spot one. But the fact that we haven’t seen such flashes yet suggests any alien visitors—if they are out there—are doing a good job of cleaning up after themselves. Daniel Clery, “If an alien ship left its trash near Earth, here’s what it might look like” at Science

Paper. (open access)

We invent explanations for not seeing the trash, quite apart from the fact that we have never seen the aliens. There, you stupid peasant, that’s real science thinking for you.

People who see no evidence for design in nature are quite prepared to believe that interstellar object Oumuamua is an alien spacecraft and that an evidence-free multiverse must really exist. And no evidence for fine-tuning of our universe for life is really evidence.

Our trash is due to packaging. It is all our fault. Any ET capable of reaching the earth would definitely have some sort of matter to energy convertor. Or an incinerator. Space doesn't care about smog.ET

So we can detect trash with our telescopes? Really? We can't even see what is on the far side of the moon without going there.ET
