Great question! No one has been through a black hole, so we don’t know. But my guess would be that you wouldn’t survive: some theories predict that spagettification occurs for an object in a black hole. The gravitational forces are so large that the object would be stretched like spaghetti!

Short answer: we don’t know how things work inside a black hole. But you would almost certainly die.
Long answer: black holes are infinitely small points so massive that nothing can escape their gravity. At the infinitely small bit, we don’t know how they work. All the bits leading up to that, we know how to calculate and they would either pull you apart or crush you.
Of course, no one has been into or near a black hole (they’re all very far away, luckily) but we can measure black holes using telescopes and they seem to behave in line with our calculations.

We don’t think its something anything can survive, including humans!
Black holes very dense and massive, so dense that they actually warp spacetime around themselves.
The result of this is called tidal forces that may cause spagettification.The moon causes tides on Earth because it pulls more on one side of the the Earth than the other so it moves the water (and ground a little bit!). The same thing would happen near a black hole. The force you felt at your feet (if you went in feet first) would be 1000 times greater than you feel at your head so it would pull you apart!
Its hard to tell if a human would just be ripped apart or if they would be stretched out like spaghetti! But either way we would not survive.All the black holes are very far away so it’s not something we need to worry about luckily!
