Wormholes may be ‘hidden’ inside black holes, study says

Wormholes, also known as Einstein-Rosen bridges, may be ‘hidden’ inside black holes, according to a study published in 2022 by scientists at Bulgaria’s Sofia University.. The research was published in the scientific journal Physical Review D, where physicists present the possibility that other scientists have already theorized in recent years.

But what is a wormhole after all? It is a theory based on Albert Einstein’s equations in his theory of general relativity; The physicist explains that space-time is curved due to the presence of mass and energy.

In this way It may be possible to create a connection between two distant points in the universeLike a tunnel that would act as a shortcut between distant regions of space; This event is so incredible that it will enable interstellar travel between extremely distant regions.

Using a computational model developed by the university team, physicists suggest that radiation from disks of matter orbiting the wormhole may be nearly impossible to distinguish from radiation surrounding the black hole. Therefore, they believe that some of these huge cosmic objects, such as Sagittarius A*, may actually be Einstein-Rosen bridges.

“Ten years ago, wormholes were entirely in the realm of science fiction. They are now moving towards the frontiers of science and people are actively researching. If you had been around, you would have found out too late. You’ll know the difference when you die or pass [por um buraco negro]”, said Sofia University study leader and partner Petya Nedkova in a message on the website New Scientist.

Black hole or wormhole?

According to the data obtained from the computational model, the polarization emitted by the black hole and the wormhole differs by only 4%. Scientists have even suggested that new technologies could distinguish these two phenomena in detail. It is important to emphasize that the Einstein-Rosen bridge is still just a theory..

Since there is currently no technology to directly observe black holes, this may take some time to resolve.

Discovery of the existence of a wormhole could provide a new future for space scienceespecially considering that these cosmic events will make interstellar travel possible. In any case, there is still a lot of data missing for us to understand the subject a little better, after all, we know very little about black holes.

“With current observations it is not possible to distinguish a black hole or a wormhole; there may be a wormhole there, but we cannot tell the difference. So we were looking for something else in the sky that might be a way to distinguish black holes from wormholes,” adds Nedkova.
