And, I have always thought (imagined) that a “black hole” is where an object departed our time frame, faster than the speed of light.
I suspect, that you could follow that path. But trying to get back?
Yet, someday, some “AI” thing might map the “black holes” of the universe. So, some places beyond the beyond, you might travel to and return from . . .
But I am thankful for the blessings of Jesus, and with God, ‘the end of time’ actually means, what we think of time, is entirely his creation: ‘The end of time’ is non-existence of time.
The Bible teaches that space was stretched out like a tent, one dimension after the other, not an explosion- a great expansion not a big bang, but, at the end of time, Jesus is said to release His grip on the elements and they will fly apart with a great noise. Space will then collapse, forming “hell” Hell is simply the old universe at the time of its death. This is why Satan u.s. always said to be crushed at his judgement. Hell in the Bible is a place of intense heat but also darkness. There is a valley between hell and the new universe which “no one may cross.”. That would be the event horizon. Hawking said time runs like normal in the center of a black hole so for the spirits trapped within, time would continue forever fueled by a universal-mass hole.
