Simulation shows how terrifying falling into a black hole would be

We've all heard of black holes, and while they sound pretty terrifying, the odds of us somehow getting sucked up into one are pretty slim.

But if you want to know what it would be like, well, you're in luck, because there's a simulator that just does that - and trust us, it's not for the faint of heart. Watch below:

If you've ever had too much to drink, or simply been unwell, and felt yourself slowly but surely losing consciousness, it's a bit like that.

As shown in the simulator, if you're sucked up into a black hole, you'll find yourself, quite literally, in a hole that gets bigger and bigger.

This happens until the sides of the mysterious object slowly but surely fade away until you're left facing nothing but darkness.

So, what exactly is a black hole? We hear you ask.

As reported by NASA, a black hole is a place in space where 'gravity pulls so much that even light cannot get out.'

In a nutshell, if you end up on one while you're off on your space travels, you're a goner.

However, while you might think that black holes are big, vast entities in space, it turns out that they vary significantly in size significantly - with the smallest coming in at the size of just one atom.

As you can imagine, the black hole simulator prompted quite a discussion on YouTube as people imagined themselves falling into endless darkness.

Reacting to the video, one viewer joked: "Big thanks for the cameraman who throw himself into the black hole to get us this footage."

"Ah yes, watching this during an existential crisis in the middle of the night was a great idea!" added a second while a third wrote: "This made me feel something I’ve never felt before. The mixture of terror solitude and sadness is unmatched."

A fourth revealed: "I watched this with my VR headset I was looking at the stars and I turned around about two minutes in. That was the loudest 'holy sh*t' of my life."

Taking how slim the odds of falling into a black hole are, a fifth wrote: "That's my number 1 fear.

"The last footage was one of the scariest [things] I've ever seen. While the simulation was getting close to the black hole I felt my anxiety rising, I don't know why.

"It's like an existential fear, being black holes beyond the physical laws that we know."

On the plus side, NASA did note that it is impossible for the Earth itself to ever get sucked up into a black hole.
