There are lot of interesting stories of blackhole but one that intrigues me is that space time is warped and change its place. That was hardest to make sense and understand but one sentence made sense:

anything pulled into blackhole will have no change of getting out and will hurtle toward its very center. That one-way travel through blackhole with no chance of ever having to travel in reverse is aking to a time in normal world where time can not go backward. Therefore space inside blackhole is really a time.

This is simplest thing I can get close to understanding space-time changing places.

Now I can not explain or describe in a normal logical sense how time inside the blackhole resembles the space in normal world. Can anyone describe?

We don't really know what's inside a black hole. Space and time may not behave as we're accustomed. It may even expand to form a new universe.

I actually wasn't aware of the concept of time and space switching roles once the event horizon of the black hole is crossed. It makes sense though because gravity affects the fabric of space/time, and in the intense gravity inside the black hole the warping of space and time becomes extreme.

Astrophysicist Matt O'Dowd of PBS Space Time does a good job of explaining both from a mathematical standpoint and from a graphical standpoint the concept of role reversal of time and space. I preferred the graphical approach to explaining it.

Time is relative. If I fell into a black hole and you watched, I would never seem to fall. From my point of view inside the event horizon, you would recede as I fell and time would not seem to change from my view point. Time is relative to a view point.
