Scientists ‘grow a black hole in the lab’ – and it starts behaving strangely

SCIENTISTS have created a black hole in a lab to test a decades-old theory by Stephen Hawking.

In a new one to learnresearchers were able to replicate the conditions of a black hole in a laboratory.

A black hole is an invisible place in space where gravity pulls so hard that not even light can escape.

The gravity in a black hole is so strong because the dense matter is confined in such a small space – this is what happens when a star dies.

In the study, a team of scientists used a single-row chain of atoms to simulate a black hole’s event horizon.

Next came something known as “Hawking radiation” – a theory proposed by the late physicist Stephen Hawking.

What is Hawking radiation?

Hawking radiation describes the hypothetical particles produced outside the confines of a black hole due to relativistic quantum effects.

There are currently two theories that aim to explain the inner workings of our universe: general relativity; and quatum mechanics.

In general relativity, events are continuous and deterministic, meaning that each cause has a specific, local effect.

In quantum mechanics, however, events produced by the interaction of subatomic particles happen in leaps and bounds, with results that are probabilistic rather than definite.

But now this new black hole simulation and Hawking radiation theory could help unify the two frameworks.

As?

Currently we have no way of knowing what happens to an object after it crosses the boundary of a black hole because no information is sent back to the universe.

But in 1974, Stephen Hawking said that these disruptions in quantum fluctuations could lead to a type of radiation that could carry some information.

And now, thanks to this new study that showed the black hole “glows” from radiation, we can analyze the properties by simulating analogues in laboratories.

“This may open a site for exploring fundamental quantum mechanical aspects alongside gravity and curved spacetime in various condensed matter environments,” the study authors write.

The new study comes shortly after researchers discovered a black hole just 1,560 light-years from Earth — closer than any other known black hole.

Named Gaia BH1, the black hole lives in a binary star system with another sun-like one star.
