Could a human enter a black hole to study it?

If you are a sci-fi junkie you've probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you'd fare all depends on the type of black hole.

Supermassive black hole at the center of our galaxy may have a friend

There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
Another reason you don’t want to get too close to a black hole is because of something we call ‘spaghettification’. If this happened to Earth it would be… unpleasant. Shutterstock

Curious Kids: can Earth be affected by a black hole in the future?

If you got too close to a black hole, it would suck you in and you'd never be able to escape, even if you were travelling at the speed of light. This point of no return is called the event horizon.

Einstein’s theory of gravity tested by a star speeding past a supermassive black hole

Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.

Curious Kids: Where do black holes lead to?

The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
