Why universe is not a black hole?
A homogeneous space cannot have a boundary, so there can be no event horizon. And the future behavior of light rays cannot depend on their directions in an isotropic space. Thus, a homogeneous and isotropic universe is not a black hole.
Are black holes baby universes?
The theory of baby universes
During inflation, baby universes could have branched from our Universe. According to Kavli IPMU researchers, a small daughter universe would eventually collapse, but the large amount of energy released in the small volume causes a black hole to form.
Will Earth ever become a black hole?
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
