Scientists have created a black hole analog in a lab to test Stephen Hawking’s theories. The researchers used a chain of atoms to simulate a black hole’s event horizon. The experiment allowed them to see a glow in their simulated event horizon under certain conditions

Here’s how the researchers created the black hole analog:

1. They created a Bose-Einstein Condensate (BEC) using a flowing gas of rubidium atoms. The BEC allows thousands of atoms to act as a single atom. 
2. They created a cliff of potential energy using a second laser beam, which caused the gas to flow like water rushing down a waterfall. 
3. This created an event horizon where one half of the gas was flowing faster than the other. 

The lab-grown black hole analog behaved just like Hawking predicted. The glow might shed light on how black holes radiate in the form of Hawking radiation. 

Black holes are places in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. 

Scientists have brought the immediate environment of a black hole down to Earth by creating a spinning disk of plasma in the lab. This ring of superheated gas mimics the matter that whips around the edge of black holes in so-called “accretion disks” that gradually feed matter to black holes

Has a black hole ever been created in a lab?

Known as a “giant quantum vortex,” this quantum fluid experiment could help scientists explore the mechanics of the always-mysterious black holes. Gear-obsessed editors choose every product we review

• Black holes are notoriously difficult to study, as they are both far away and so massive that not even light can escape. 
• So, scientists from the University of Nottingham created a “giant quantum vortex” using a helium superfluid with 500 times less viscosity than water. 
• These Earth-bound vortices could help experts understand black holes—or even inch closer to a Grand Unified Theory

By using superfluid helium (with a viscosity 500 times lower than water), the researchers managed to create a quantum simulator by placing the helium in a tank with a spinning propeller. Due to the extremely low-friction and vortex-like environment, this particular helium begins exhibiting “unusual quantum effects,” according to New Scientist. These effects allowed the team the team to observe black hole-like phenomena, such as “ringdown mode” and cosmic fields interacting with the gravitational vortices. Their latest work was published on the preprint server arXiv in 2023, and was last revised this past November. The paper has yet to be peer-reviewed.

According to quantum field theory, there is no such thing as an empty vacuum. Space is instead teeming with tiny vibrations that, if imbued with enough energy, randomly burst into virtual particles — particle-antiparticle pairs that almost immediately annihilate each other, producing light. In 1974, Stephen Hawking predicted that the extreme gravitational force felt at the mouths of black holes — their event horizons — would summon photons into existence in this way. Gravity, according to Einstein’s theory of general relativity, distorts space-time, so that quantum fields get more warped the closer they get to the immense gravitational tug of a black hole’s singularity. 

Scientists are no longer dependent only on astronomical observations to gain information about black holes. Now many types of computer models have been created and by filling in the available information, new information related to black holes is being obtained as a result. Although it is said about black holes that nothing comes out of them, but by simulating the event horizon of a black hole from a single computer file, scientists have found that a kind of glowing radiation ( Glowing Radiation) will be seen

Possibility of coordination between two concepts
This radiation is of the same type which is called Hawking radiation. Hawking radiation consists of the radiation of particles produced by the disruption of quantum fluctuations caused by the rupture of spacetime by the black hole. Researchers think it can be used to reconcile two different hypotheses that explain the universe. General theory of relativity and quantum mechanics

There is a contradiction between both
While the theory of relativity explains spacetime in terms of the behavior of gravity and its effects, quantum mechanics explains the behavior of subatomic particles through mathematical probability. There are many contradictions in both the theories. But both explain different processes but often where one is right, the other is wrong

But in 1974, Stephen Hawking proposed that due to the disruption of quantum fluctuations caused by the event horizon, a special type of radiation is released which is similar to thermal radiation. If Hawking radiation really exists, there is very little chance of detecting it so far. We may be able to experience or see it at any time in the universe.

Israeli researcher Jeff Steinhauer created an artificial black hole in a lab by using laser beams on a Bose-Einstein condensate. The black hole traps sound waves instead of light and information

Scientists have also simulated a black hole in a lab using a chain of atoms to mimic the event horizon. This experiment observed Hawking radiation, which are particles caused by disturbances in the black hole’s break in spacetime. The experiment also found that quantum entanglement is necessary for Hawking radiation

Creating black holes in a lab could help researchers answer fundamental questions about quantum mechanics and gravity. For example, the research has shown that Hawking radiation can be studied in an environment that isn’t influenced by the formation of a black hole. This could lead to a new theory that unites quantum mechanics with general relativity

Black holes are the simplest possible object in general relativity, and nothing can travel through spacetime faster than light, including black holes. However, the extreme curvature of spacetime near a black hole can cause time dilation, where time passes very slowly compared to on Earth. This could potentially lead to time travel
