When contemplating the perspective from within a black hole, it’s crucial to consider the bizarre nature of spacetime in these regions. As you approach a black hole, especially past the event horizon, the rules of physics as we understand them change dramatically. From an observer outside a black hole, any object falling towards it appears to slow down and take an infinite amount of time to cross the event horizon due to the immense gravitational time dilation. Hence, the outside universe would observe you seemingly frozen at the horizon.
However, from the perspective of an observer (or any hypothetical sensor) inside the black hole, the situation becomes more complex. If we speculate about surviving past the event horizon—considering it’s currently impossible due to spaghettification (extreme stretching) and immense tidal forces—the perception of time could be drastically altered by the intense gravitational field. The time experienced by someone inside is thought to be different because of this dilation.
Regarding the question of whether the universe would appear paused or fast-forwarded if viewed from inside, the answer leans towards fast-forwarded. The outside universe’s perception of time would seem to accelerate due to the extreme relative time dilation. As you approach the singularity (the center of the black hole), your own time frame continues normally, but the universe outside would appear to speed up. Essentially, vast spans of time would pass outside while very little passes for you, giving the illusory sensation that the universe is on fast-forward. This concept remains largely theoretical and speculative due to the inability to empirically verify these experiences inside a black hole.
