It relatively relies upon on despite if or no longer our universe is in the form horizon of the black hollow. If our universe became into contained in the form horizon, I think of an exterior observer might see some thing like we notice while staring at a black hollow it is pulling count number off a celebrity, however the priority subsequently might probable be greater like planets, moons, stars, etc. subsequently, we'd probable have already reported the phenomenon as a brilliant black spot in the sky. we would have observed the disappearance of all that mass, that's available that shall we pass over it, even nonetheless. The universe is a large place. If our universe became into ouside the form horizon, then an exterior observer ought to in straightforward terms notice our universe to be orbiting the black hollow (with different universes?). We, on the different hand could be conscious no longer something, as we can not yet view different universes(in the event that they do certainly exist) to be conscious that they are changing place. it relatively is basically me questioning the priority by, it is not in accordance with certainty or something, so do no longer take my notice for it. Sorry i won't have the ability to be greater help.
