This lack of memory of its past, means that a black hole has only three properties its:
Everything else is lost. They're a lot like fundamental particles in that respect. This actually means that every single black hole in the universe is the same.

Space and time are the grand stage where the play of the universe unfolds. But space isn't a fixed stage and doesn't tick the same for everyone everywhere. In short, they are relative. Matter bends space and bent space tells matter how to move.

No one knows. We can only see their outsides, and the theories we have probably get their insides wrong.
But it's okay not to now everything. It just means there is still work to be done. It means there are still mysteries to be solved and big dead to t...

Black holes do not just bend the stage, they are like trap doors. Places with so much mass that the universe formed a 'no-go' zone where the rules change.

We can still observe black holes because of ther effect on matter. Things can orbit black holes just as they can orbit the sun or a planet.

In the center of the black hole, we find the singularity. A single point with all the matter that has ever crossed the event horizon, all crushed to a point infinitely small.

If you look directly at a black hole it looks like nothing. the space is under their control is blocked by an invisible one way border called the event horizon.
The event horizon forms a sheel around a region of space that, once entered, is shielded from the rest o...

Also, basically everything you've ever read about black holes, is about theoretical black holes that aren't spinning, because their math is so much easier.

But getting close to a black hole can be incredibly dangerous. A painful death by 'spaghettification' awaits you.
Because you feet are closer to the black hole than your head they feel a stronger pull of gravity, enough to pull you apart.

When this happens near the event horizon of a black hole, one of these particles call fall in, stopping them from annihilating.

Gravity also alters the passage of time itself. The stronger the gravity the slower time passes. While you watch the universe above you speed up, those far away will watch you in slow motion.

The singularities of rotating black holes are even wilder. The rotation causes them to swell outwards into a sort of rinularity.
This rotation is so powerfull, that space itself is dragged along.

First of all, you would see the strangest funhouse mirror in the universe. Matter isn't the only thing orbiting a black hole: Gravity is so strong near them that light can orbit too.
