EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
Those two examples were mostly joking, I think by now we don’t need to detect black holes either. We’ve seen them.
You can’t “see” a black hole.
