What can destroy a black hole?

How much is 1 minute in black hole?

“If you were to stand just outside the event horizon of Sagittarius A*, and you stood there for one minute, 700 years would pass because time passes so much slower in the gravitational field there than it does on Earth.” Some have suggested that black holes could be used for time travel.

Is a black hole the absence of space time?

A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, has enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Is A black hole a portal?

Black Holes Are Not ...

They don't provide shortcuts between different points in space, or portals to other dimensions or universes. Cosmic vacuum cleaners. Black holes don't suck in other matter. From far enough away, their gravitational effects are just like those of other objects of the same mass.

Can black holes be used for space travel?

There's no evidence one can go through wormholes or black holes (which certainly do exist). No evidence at all that if you COULD travel through a wormhole or a black hole that you would or could survive, no evidence you could move faster-than-light, find yourself across the Universe, or enter another universe, none.
