Physicists succeeded in simulating a small “black hole”.

Research in the field of black holes never stops, these cosmic monsters armed with a tremendous force of gravity, animal astronomers and physicists have long puzzled over it and searched for the key to solving its mysteries.

In recent research reported by the British website “Indy100”, a team of physicists from the Dutch “University of Amsterdam” used a series of atoms lined up in a single row to better understand the behavior of black holes. are, and were created, in a space. simulation process, a region surrounding the black hole is called the “event horizon”. The horizon of the event, or “the point of no return” as many like to call it, because there is no written return for any crime or substance in this limit, which is like a membrane that allows the passage of material in one direction.

The creation of this artificial “event horizon” proves a theory formulated by Stephen Hawking, one of the leading astrophysicists of the modern era, in 1974 that a black hole emits a rare form of thermal radiation, named “Hawking radiation” after the scientist himself. .

Hawking radiation

In the latest astronomical breakthrough, scientists studied the properties of “Hawking radiation” from an isotope black hole created in the laboratory. And “Indy 100” cited a report prepared by the “Science Alert” website, that this thermal radiation appears when “particles produced by disturbances in quantum vibrations from the black hole break through the fabric containing four dimension is called “space-time”.

As a reminder, space has three dimensions: length, width, and depth, while Albert Einstein added time as a third dimension to his theory of relativity, when he saw the universe as a four-dimensional composite of time and space. , and abbreviate it. and the word “space-time.”

But for the radiation itself to show a glow is a strange anomaly in the theory of the world of space. The event horizon of a black hole is supposed to be a region where neither light nor matter can ever escape.

In science class, for example, we all learn about the great power of the black hole, and how if we’re unlucky and find ourselves face to face with it, it will pull us into its mouth until it eventually swallows us all.

This is due, as explained in the “Indy 100” website, to the density of the black hole in a certain range of the center, so even an attempt to travel outside the speed of light (or any speed in the universe in relation and matter) will not prevent everything or anyone falling inside the black hole from this fate.

In the simulation, a one-dimensional array of atoms forms a kind of path for electrons to “jump” from one place to another. By adjusting the way this jumping process is done smoothly and easily, physicists can cause certain properties to disappear, creating a sort of “event horizon” that overlaps with the wave nature of electrons.

And “Indy100” cited “Science Alert” that the effect of the “event horizon” artificial in the new study caused an increase in temperature that matches the theoretical expectations for an isotopic system “black hole”, but only when a part in the chain of atoms. used in the simulation extends beyond the “event horizon”.

As a result, compliments of particles extending across the event horizon are thought to play an important role in generating Hawking radiation.

In light of simulations that began to imitate space-time as “flat space,” scientists say the radiation was only thermal in a certain range of electron “jump amplitude.”

Thus, Hawking radiation is thermal only under certain circumstances, and is only possible when gravity causes a change in the warp of space-time.

In their paper, published in the journal Physical Review Research, the scientists write that the simulations “would serve as a precursor to the exploration of fundamental aspects of quantum mechanics beyond gravity and curved space-time in various conditions of condensed matter.”
