The General Theory of Relativity was published by the genius of physics over a century ago, to refine Isaac Newton’s law of universal gravitation. Providing a unified description of gravity as a geometric property of space and time, or spacetime, this model is still currently used by scientists as a description of gravity in modern physics. Einstein’s theory has important astrophysical implications because it alludes to the existence of black holes – cosmic phenomena in which space and time are distorted in such a way that nothing, not even light, can be seated. ‘escape.
Now scientists are theorizing that it might be possible to artificially create a black hole inside a particle collider, but Einstein’s rules would have to be broken.
Presenter Hank Green revealed in a recent episode on SciShow’s YouTube channel how the idea came about.
He said: “There was a lot of excitement when the Large Hadron Collider (LHC) was first turned on in Switzerland.
“The particle accelerator was the largest ever made, representing decades of work by thousands of people and promising to unravel some of the deepest mysteries in the universe.

“But some were not that excited.
“In fact, they were afraid the LHC would make a black hole and destroy the Earth.
“It wasn’t true and the fear was the result of rumors, but there was actually a kernel of truth in the idea.”
Mr Green went on to explain why some scientists believe the idea might still be possible.
He added: “After all, some theoretical physicists believed that the LHC could create a black hole – it would be just a submicroscopic hole that would instantly disappear.
“But although the accelerator has yet to find any of these micro black holes, it is still believed that maybe the next generation of particle accelerators can and if they can, it would provide evidence for further studies. fascinating ideas in theoretical physics.

“We’re talking about things like extra spatial dimensions.
“The basis of this idea is that black holes are not just things in space, they are a natural consequence of Einstein’s general theory of relativity.
“Theory tells us that matter distorts the fabric of space-time, and the more matter there is in a region of space, the more it distorts its surroundings and brings nearby objects closer together.
Mr. Green went into more detail on the theory and where Einstein fits into it all.
He continued, “If there is a lot of matter in a very small volume, then space becomes so distorted that it becomes impossible to move away from matter if you get too close – it’s a black hole. .
“While they usually form when huge stars collapse, they can technically form anytime there is enough material in a small area, so it’s possible to get very small ones.

“In a lot of its experiments, the LHC crushes extremely light particles – protons – together very quickly, which allows us to learn all kinds of things about what happens when particles collide.
“But these super-fast protons have a lot of energy for their size, and that’s a big deal when it comes to black holes.
“In the high-energy collisions of the LHC, mass and energy actually become interchangeable and this is the aim of Einstein’s famous E = MC2 – he says mass is proportional to energy.
But, the presenter explained why such a breakthrough would challenge the fundamentals of physics.
He said last month: “So, theoretically, if you really bring ultra-fast particles together, the energy of that motion in one place can act like a lot of mass and be enough to form a black hole.
“The problem is, with our current understanding of physics, that can’t happen at the LHC.
“To create the lightest black hole possible, the particles would each need around 10 quintillion electron volts of energy, and the LHC can get particles up to 14 trillion electrons volts.
“But there’s a reason some physicists are still thinking about all of this and it’s because these calculations all assume that there aren’t problems with general relativity.
According to the show, the theory is not as controversial as it looks and Mr. Green explained why there were reasons to question Einstein’s theory.
He added: “We already know that the theory has problems – it’s very good at making a lot of predictions, but technically it also predicts that it should be possible for places to have infinite density and we know that this. is not a thing.
“So what’s probably happening is that general relativity is approximately true and there is a more correct theory that we don’t know.
“This theory might produce different rules when you have a lot of energy in a very small space, which would solve that problem.
“Right now, scientists think this new theory is likely to be some kind of quantum gravity – a combination of quantum mechanics and relativity and there are already a few candidates.
