Do we know what it is like inside a black hole

...and will we ever be able to find out?

There is a boundary around a Black Hole which is called the Event Horizon, this is where the escape velocity is equal to the speed of light. It is impossible to see beyond it, and nothing can escape from beyond that boundary.

All of our known laws of physics break down in a Black Hole.

We'll probably never know for sure, because we can't see them (light can't bounce off the surface) and our mathematical models break down at that level, giving us "divide by zero" errors and preventing us making accurate models.

But what's probably down there is a small body--maybe about the size of the Earth, give or take, depending on the mass of the black hole. That body won't be made of ordinary matter, though--it's composed of what's called "degenerate matter". The pull of gravity is so strong that it pulls atoms apart and forces the subatomic particles (protons, neutrons, electrons) to be squashed up against other particles. As you approach the surface, also, tidal forces start to become unbelievable: the difference in gravitational pull between your feet and your head would grow so strong that it would pull you apart in a process astronomers colorfully call "spaghettification".

There are no accepted answers within the science community due to our inability to dive into one and to survive to tell the tale. It is said that we would stretch into infinity and be ripped apart atom by atom until there is nothing left of us.

Pseudo science predicts that if we were to see anything, it would either be streaks of light entering into a single point or that everything is frozen in time.

I hope this helps friend.

A black hole is a star that has a mass so big (millions of Solar masses) that not even light can escape its gravity. I don't think we will be able to "see" what's it like inside a black hole, everything we might throw at it won't come back - not even light!

Black and deep.

Soft and warm ;)
