Black Holes Could be Sending Matter into the Future

Essentially, it's time travel.

It turns out that black holes could, in fact, be a sort of a tool for time travel.

Some astronomers have recently suggested that space-time curves extremely near the center of a black hole, but it does not break and rather continues in a region in the future that has the structure of a white hole.

This idea proves that Black Holes are definitely among the strangest objects in the universe.

According to Einstein‘s General Theory of Relativity, everything that enters a black hole will continue to fall toward its center, attracted by an increasingly stronger gravity, until it compresses into a single point of such density that the very space-time fabric would break.

That point, called a singularity, is where the laws of known physics would have no effect, the very time would stop and reality as we know it would completely vanish.

But some astronomers don’t seem to agree.

According to Abhay Ashtekar and Javier Olmedo, from Pennsylvania State University, and Parampreet Singh, from Louisiana, and two recently published papers in Physical Review Letters and Physical Review D, things could be very different.

In fact, their work could forever change what we thought we knew about black holes.

Especially in regard to the true nature of their centers, which according to these researchers “we could have greatly misunderstood.”

They suggest how black holes transition into white holes.

The main problem is the singularity.

The simple idea that there may be those points that, despite having an infinite density, do not occupy any space, is considered an aberration, something that can not exist in nature.

Until now, and under the umbrella of “quantum gravity” (which essentially means gravity at the smallest scales), numerous researchers have formulated various theoretical proposals, developing completely new mathematics that can serve to describe how gravity works in the microcosm of subatomic particles.

Astronomers point towards the so-called “loop quantum gravity“, which among other things predicts that spacetime can be quantified so that there is a minimum unit beyond which spacetime cannot be further subdivided.

Well, by applying loop quantum gravity to the central points of black holes, the researchers claim that the result was not a singularity, but something very different.

But, if it’s not a singularity, what else could it be?

New calculations predict that spacetime curves very strongly near the center of a black hole.

But it does not break but continues in a region in the future that has the structure of a white hole.

A white hole is like a black hole but the other way around, that is, instead of attracting matter to itself, it “shoots” it outwards, into space.

Experts say that in the presence of very strong gravitational fields, time slows down.

And black holes contain what are thought to be the strongest gravitational fields in the universe.

Because of this, a possible interpretation of this new work is that matter falls into a black hole and then “bounces”, firing the mass through the cosmos.

Because time is very slow near the center of a black hole, seen from outside that process would last a huge amount of time.

If researchers are right, in the very distant future, where there are now black holes, matter will explode, scattering it throughout the cosmos through white holes.

The idea is fresh, and very suggestive, although before being considered valid it will be necessary to test it experimentally.

And it turns out there are several ways to do it.

For a long time, for example, scientists from all over the world have been detecting a series of enormously energetic phenomena that refuse to be explained.

These are high-energy cosmic rays that collide against Earth’s atmosphere from time to time; and the so-called FRBs (fast radio bursts), which occur when a huge amount of radio energy is detected in a very short period of time.

According to the authors of the new papers, both phenomena could be, in principle, the signature of a black hole transitioning to a white hole.
