I ignored all those headlines shouting about "scientist finding a black hole that shouldn't (or can't) exist" because it obviously exists. Sure, we can't explain why it exists now, but with future observations on it (and more objects like it that will probably be found in the future), it should be resolved. Read this by Phil Plait instead.
@sohkamyung maybe it's from nearby galaxies.. just like an interstellar astroid we've seen recently
@vjy Not likely, I think. A visitor from another galaxy would be travelling at a velocity (speed and direction) that doesn't match stars from out galaxy, and astronomers would have noticed that.
BTW, the interstellar asteroid/comet spotted is probably from our galaxy too. Interstellar does not necessarily mean 'not from our galaxy': it just means it's not from our solar system.
