Obviously, it wouldn’t be good; but what happens if you fall in a black hole? Black holes are a region of space-time that has an extreme amount of gravity.
The gravity is so incredibly strong, that no particles or electromagnetic radiation are able to escape. That means you’re fate is inevitable as well. You can never escape.
What Happens in a Black Hole
How do black holes form? Black holes are basically the ‘remains’ of dead stars. After a star has used all of its nuclear fuel, the stars core collapses in on itself, to create an incredibly dense black hole. How dense is a black hole? A black hole is typically 100 times more dense than an atomic nucleus.
There is only one thing that is able to escape a black holes intense gravity. Energy. Quantum effects at the event horizon (the boundary of a black hole, where nothing can escape) radiate out streams off hot particles. A type of radiation called hawking radiation.
Black holes are destined to radiate away its mass, up until the moment it no longer exists. It is then that the black hole will be gone.
How can we detect something without it emitting any particles? The only way to detect a black hole is from stars that lose part of their mass, because they came to close to the event horizon.
At the centre of a black hole is something called the singularity. It is where the intense gravity of the black hole curves spacetime itself, leaving the laws of physics to stop operating. All of the theories we have developed about what lies in a black hole are mere speculations.
So, what would happen if someone fell in a black hole? If you had the unfortunate luck of getting to close to a black hole, passing through/into the event horizon you will get spaghettified (yes that’s a real term).
The reason it is called spaghettification is because, when passing too close to a black hole, we would be pulled apart and elongated, becoming a stream of subatomic particles, swirling around the black hole eventually finding the singularity.
However, the closer you get to the event horizon, the slower time is for you. You would seem to slow and then stop to anybody who is watching your unfortunate demise. As you fall into a black hole you would be getting closer to the speed of light.
After being pulled past the event horizon, any observers watching would see you freeze and then you would just freeze in time, appearing to stop and stay perfectly still.
For you, time would be normal, so it would be rather quick and unpleasant. After being spaghettified, you would not live to see what is inside the singularity, as you would have died hundreds of miles before you reached the singularity.
How do we know this will happen if we can’t see it happening? In 2014, astronomers watched as a star passed too close to the black hole and was spaghettified. Some of the matter did not reach the event horizon, allowing us to see what was happening.
