How it works: Black Holes
Fucking black holes. How do they work?
A black hole is what you get when a large amount of mass is compressed into a very very very small area.
For instance, if the entire Earth were crushed to the size of a ping-pong ball.

Not to scale.
The most important thing to remember about black holes is that what goes in a black hole, stays in a black hole.

Like Las Vegas, if Las Vegas crushed you down into an infinitely small point.
You typically end up with a black hole when a very large star runs out of fuel, and begins to collapse. Eventually the rate of collapse overwhelms the gas the star is composed of, and the entire structure collapses down into a singularity, a single point with infinite density and zero volume.
Because of the strength of gravity around this singularity, nothing can escape from it.

Not even D.B. Cooper.
In fact, not even light can escape the gravitational pull of a black hole, which is why they appear to be black. As a result, this means that no information can leave a black hole, which makes them difficult to study.

A black hole would never talk with Julian Assange.
What we know of black holes comes primarily from theory. In theory, this is what would happen to you if you fell into a black hole:
As you approached the black hole, time would seem to run more slowly for you. (in other words, things around you would appear to speed up.)
Passing the point of no return (the event horizon, where the escape velocity of the black hole is greater than the speed of light), you might feel a significantly larger tug on your shoes than on head. (assuming you went feet first.)
This tug would get progressively larger as you fell towards the singularity: gravity would affect your shoes more than your head.
Eventually you’d be ripped to shreds by this force, most likely killing you to death. You might not notice, though, because you’d be too busy watching the entire future of the universe playing in fast-forward above you.
Of course, there’d be no way to tell anyone else about this experience because no information can leave the black hole. But it’d probably be damn cool.
