10 Craziest Facts You Didn't Know About Black Holes

3. Black Holes Slow Time

That's right. If literal space bending around black holes wasn't weird enough to comprehend, they also SLOW TIME.

Basically, there is no space AND time. They're both one thing. Spacetime. Timespace. Spimetace?

As space is stretched around a black hole, so too is time, but the way we understand 'stretched' time is that it is slowed down.

If you watched someone fall into a black hole, you would watch their movements become slower and slower before eventually freezing still, and then proceeding to disappear into the abyss.

For the person falling into the black hole, they would see time around them speed up like the universe was being fast forwarded.

The film Interstellar explains the bending of both space and time pretty well, and the way the black hole was generated in the film actually used the maths behind black holes to render a 3D image.
