Scientist reveals exactly what would happen to your body if you walked into a black hole

A new theory shares that there could be black holes floating in the universe that could pass through your body

When it comes to out of space matters, many things seem unusual and seem like out of this world concepts, excuse the puns. Black holes are included in this.

If you need a reminder of what a black hole is, it is described as 'a region of space having a gravitational field so intense that no matter or radiation can escape', according to Oxford Languages dictionary.

However, whilst many of us have often thought of black holes as something we don’t have to consider coming near to us, some scientists have a new theory that there could be smaller versions of black holes that could run through you at any time.

Now this is certainly something the average person hasn’t considered before.

These black holes are being named as 'primordial' black holes (PBH) and have massive masses ranging from 100,000 times smaller than a paper clip to 100,000 times bigger than the sun. A huge range, right?

So imagine what it would be like to pass through a black hole.

What would a black hole do to the human body?

Well, hang tight, as we are going to dig deeper into this.

Professor Robert Scherrer, a physicist from Vanderbilt University, explained in his paper: “A sufficiently large primordial black hole, about the size of an asteroid or larger, would cause serious injury or death if it passed through you.”

Practically, he says it would be 'like a gunshot'.

In line with the Big Bang theory, primordial black holes are thought to have been formed in the first few moments of the Universe. This school of thought believes that these black holes formed as immense clouds of matter, and fell straight into singularities.

At the moment, primordial black holes are nothing more than a theory. But the idea is that these black holes from the Big Bang could have been gradually shrinking over the past 13.8 billion years.

What would happen if one of these tiny black holes passed through your body?

Professor Scherrer says that if a PBH went through your brain, it 'would be sufficient to pull apart human brain cells', he explains further in his paper, published in the International Journal of Modern Physics D.

However, there’s no need to be sent into panic, because although this sounds gruesome, Professor Scherrer says there isn’t a real reason that we should be worrying.

He says: "A smaller primordial black hole could pass through you, and you wouldn't even notice it.

"However, the density of these black holes is so low that such an encounter is essentially never going to happen."

There is also no evidence that someone has ever been killed by a black hole. So, this should be comforting to put into further perspective the likelihood of this happening.

Be assured that you are safe from black holes... for now!
