Can the milky Way galaxy to be a portal to a distant universe

In the opinion of a group of scientists from India, Italy and USA, our galaxy the milky Way may be a cosmic "wormhole" — an exotic short cut across the Universe, which is familiar to you from movies and books of science fiction. Such a wormhole can be an alternative to dark matter to explain missing mass in our galaxy, say scientists in a paper published in The Annals of Physics. Moreover, the wormhole can be pay. However, the scientists have not confirmed the existence of a galactic wormhole.

The so-called cosmic wormholes have been a staple of science fiction for many decades. In books and films they were presented as a way to travel to distant worlds, such a short way through the Universe. This wormhole was depicted in the recent film "interstellar". Anyway, the real analogues of wormholes in theoretical physics there are — there they are known as bridges Einstein-Rosen.

"The distribution of dark matter in our galaxy simulates the presence of a stable wormhole, which we derived by solving the standard equations of General relativity," — said Dr. Paolo Colucci from the International school for advanced studies in Italy. Colucci refers to the General theory of relativity, according to which the milky Way must be more mass than we can calculate on the basis of all the observed stars, planets, dust and gas clouds.

Of course, this is a problem. Not only the milky Way but other galaxies. Galaxy — like stars with planets spinning. But the number of visible matter in them just enough to not allow them to scatter. They have a gravitational pull that is stronger than it should be at first glance. Scientists believe that this thrust produces a halo of dark matter that surrounds the galaxy.

The General theory of relativity, which works well with gravity on cosmic scales, can be used to calculate the amount of present dark matter. But what is this dark matter? Whether it consists of exotic particles? Is a force of another dimension? Do we need to modify our theory of gravity?

Cosmologists have worked for years on this and other theories, trying to explain the true nature of dark matter. However, it remains one of the biggest mysteries of modern cosmology.

Team Colucci, under the leadership of Farouk Rajamani from the University Jadavpur in India found that the same equations of General relativity that describe dark matter may also explain the presence of wormholes.

They managed to do this by combining the equations with a detailed map of the distribution of dark matter obtained by scientists in 2013. The effects of the presence of the wormhole must be the same as the effect attributed to the galactic halo dark matter.

However, usually, wormholes means a passage through matter allowing "cut" cosmic distances. Could it be that in the milky Way? Our galaxy, like all large galaxies, has a supermassive black hole in the center. Can it be that wormhole?

Says Colucci, "it is not so, and we have not yet solved the Einstein equation for this region. Instead, we assume that the wormhole might be the size of the whole galaxy."
