Could Large Hadron Collider 2.0 form black hole on Earth?

The LHC is already a whopping 27 kilometres in length but the next one will range from 80 to 100 kilometres, it has been revealed.

The LHC 2.0, or Future Circular Collider (FCC), will revolutionise the world of physics when it is up and running, and build on the work of its predecessor.

However, as it will be much more powerful, some fear that it could create a devastating black hole.

Researchers have discovered that it actually takes 2.4 times less energy to create a black hole, and with a more powerful particle collider, some fear that one could be accidentally made in the lab.

When particles smash into one another, their gravitational pull is trapped, meaning researchers could make one at the LHC 2.0.

If enough energy is contained between those particles, it can collapse that could create two black holes that quickly merge into one.

The study published in the journal Physical Review Letters reads: “We find that the threshold for black hole formation is lower (by a factor of a few) than simple hoop conjecture estimates, and, moreover, near this threshold two distinct apparent horizons first form postcollision and then merge.“

However, thanks to a process known as Hawking Radiation, experts say that Earth is in no danger of being swallowed by a man-made black hole.

Professor Stephen Hawking claimed black holes are slowly evaporating in a groundbreaking theory 42 years ago in 1974.

His theory said particles could rob black holes of their energy making them disappear at a minuscule rate as they release everything they had once swallowed in a trickle of dust – this theory was proved last year.

Frans Pretorius, a theoretical physicist at Princeton University, told LiveScience: “The one common misconception about the small black holes that may form at the Large Hadron Collider is that they would swallow the Earth. 

“With about as much confidence as we can say anything in science, this is completely impossible.”
