is it possible that the universe is a black itself because of its mass and size?

Question

is there any proof/evidence?

i meant BLACK HOLE <<<<<<<<<<<<<<<<<<<

Answer 1

If we assume that light can never escape from the universe, in other words that space is curved and closed, then we are indeed
living inside the biggest black hole there is. This isn't too surprising, since the density of a black hole decreases with its size.

Answer 2

Black Holes are black because their gravity is so strong that even light cannot move fast enough to escape. Light is required to bounce off something to see it, so the absence of light reflected makes it appear black.

It's gravity is related to it's extreme mass and infinitly small size, so you're basicaly correct.

Answer 3

if the universe is truly constantly expanding, there is no light to be reflected of the "edge of the universe" so all we see is darkness. we see color because different wavelengths are absorbed by specific objects. certain wavelengths of light are bounced back and that is the color we see. if no light can be bounced back because it would never reach the edge, we cannot see the edge therefore, we see the absence of light, darkness.

Answer 4

I guess it's just as likely a scenario as one where we are actually living in a snow globe on some giants desk! Until we discover the farthest reaches of our own galaxy, we'll never know. It is kind of freaky to think about. I mean, our galaxy is possibly one of many galaxies in space, but where is that "space"??
