When this happens, gravity pulls the centre of the star inwards quickly, and collapses into a tiny ball.

This happens when stars run out of fuel – like hydrogen – to burn, causing the star to collapse.

Most black holes are made when a supergiant star dies.

Conventional laws of physics stop applying at this point.

At the singularity, space-time curves infinitely and the gravitational pull is infinitely strong.

It's a one-dimensional point that contains an incredibly large mass in an infinitely small space.

The gravitational singularity is the very centre of a black hole.

The event horizon varies between different black holes, depending on their mass and size.

The point at which you can no longer escape from a black hole's gravitational pull is called the event horizon.

Otherwise literally everything in the universe would have been sucked into one.

There has to be a point at which you're so close to a black hole you can't escape.

They get their name because even light can't escape once it's been sucked in – which is why a black hole is completely dark.

That's because they have extremely strong gravitational effects, which means once something goes into a black hole, it can't come back out.

A black hole is a region of space where absolutely nothing can escape.

So, even if you do find yourself with the opportunity to take a cosmic cliff dive into a black hole, for safety reasons, you probably should resist the urge. Unfortunately, because nothing can escape a black hole’s event horizon - not even information - we’ll never know for certain what happens when matter falls past the point of no return. No material that falls inside a black hole could survive intact. Of course, no matter what type of black hole you plunge into, you’re ultimately going to get torn apart by its extreme gravity and die a horrible death. (Not to mention the wild time dilation effects.) Meanwhile, you’d see that everything within the event horizon was warped by extreme gravitational forces, thanks to an effect astronomers call gravitational lensing. Even if you were holding a flashlight and tried to shine it out, the light would fall back down into the singularity with you.

But no one would be able to see you once you passed beyond the event horizon. In this case, at least in theory, you could see out into surrounding space. Although the end result - a horrible death - would still be your fate, you might actually make it all the way through the event horizon and manage to start falling inside the singularity itself while still alive. In contrast to falling into a stellar-mass black hole, your experience plunging into an intermediate-mass or supermassive black hole would be slightly less nightmarish. Scenario 2: Falling into an intermediate-mass or supermassive black hole You would literally end up looking like a piece of spaghetti. Each bit of your body would also be elongated in a slightly different direction. So, if you jumped into the black hole feet first, the gravitational force on your toes would be much stronger than that pulling on your head. This is because the black hole’s gravity compresses your body horizontally while pulling it like taffy in the vertical direction. That means you only have to get slightly closer to a small black hole to experience an extremely noticeable difference in gravity.Īs you floated through space toward a stellar-mass black hole, you’d be stretched in some directions and squished in others, a process that scientists call spaghettification. That’s because smaller black holes actually have a more intense gravitational gradient than larger ones. Stellar-mass black holes are puny in comparison to their bigger cousins, but they actually boast the strongest tidal forces of any type of black hole. Scenario 1: Falling into a stellar-mass black hole Intermediate-mass black holes are still mysterious, and only a few suspected examples have been discovered, but astronomers think they may form through a similar process of accretion, just on a smaller scale. Supermassive black holes live in the centers of most galaxies, and are thought to grow to their extreme sizes - up to tens of billions of times more massive than our Sun - by consuming stars and merging with other black holes. Stellar-mass black holes form when the largest stars exhaust their fuel and collapse in on themselves.

At the simplest level, there are three kinds of black holes: stellar-mass black holes, supermassive black holes, and intermediate-mass black holes. There are a few different types of black holes, so if you were to jump into one, your exact fate would depend on which sort of black hole you chose.
