Physicists named the conditions for the appearance of wormholes: changed conditions of gravity are needed

After conducting research, scientists have found that travel through the wormhole is possible. However, this requires non-standard gravity conditions.

João Rosa, a physicist at the University of Aveiro in Portugal, has long attempted to virtually “build” a stable traversable wormhole that can be traversed safely without collapsing a theoretical passageway or capturing its occupant. And recently he discovered that this is indeed possible, but only if the conventional understanding of gravity is changed.

Wormholes are deceptively easy to construct – on paper – using the concept of gravity. In Einstein’s general theory of relativity, gravity defines the relationship between matter and energy, space and time. The trick for creating a wormhole is to find a configuration of matter and energy that will form a tunnel that connects two distant points in space. The idea of ​​such a fancy label has captured the imaginations of scientists and science fiction writers for decades.

However, wormholes built on the criteria established by general relativity suffer from a serious problem: they are actually impassable. The entrances to wormholes are hidden behind event horizons, which are one-way barriers in space. This means that if you enter a wormhole, you can never leave.

Another problem is that they are very unstable. The moment even a single photon or light particle hits the tunnel, the entire wormhole collapses before the light particle can escape.

To solve these problems in general relativity and stabilize the wormhole, the space traveler must fashion a wormhole from an incredibly exotic ingredient – a form of matter that has negative mass. Negative mass (also known as exotic matter) is a type of exotic matter in theoretical physics that has a mass opposite to that of normal matter, such as −1 kg. So far, scientists have not observed negative mass anywhere in the universe. Because such matter is so rare, it seems impossible to create an entire wormhole of exotic matter in our universe.

But all this talk of wormholes is based on general relativity. And, although this theory of gravity has withstood all the observational and experimental tests thrown to it over the past century, it is known that it is not the last word when it comes to gravity. For example, relativity is unable to describe the centers of black holes, the earliest moments of the universe, and the relationship between itself and quantum physics.

The research results are published in the preprint of the arXiv repository, until it is peer-reviewed.
