Is there gate to another galaxy or universe somewhere in our Milky Way galaxy? After the published paper by the collaboration of a group of scientists from different countries (Farook Rahaman, P. Salucci, P.K.F. Kuhfittig, Saibal Ray, Mosiur Rahaman), very possibly,similar results are found also by A. Ovgun and M. Halilsoy from Eastern Mediterranean University, located in Cyprus (link to paper in ArXiv).
Scientists believe it would be possible to navigate through the wormhole, which would be a lot like a real-life version of the space-time tunnel portrayed in the hit movie Interstellar.
Our very own Milky Way or other galaxies could be home to a giant tunnel in spacetime.
At least, that’s what the authors of a new study have proposed. It is believed that the outer halo of our galaxy may harbor enough dark matter to support the creation and sustenance of a “stable and navigable” shortcut to a distant region of spacetime — a phenomenon known as a wormhole. In this study, by using suitable dark matter density profiles, they manage to build wormhole in the off-center region of Milky Way galaxy and also other galaxies. At the very center on the other hand it is believed that there lies a supermassive black hole.
The large amounts of dark matter could provide this fuel. Using a model of dark matter’s abundance that is based on the rotation curves of other spiral galaxies, the researchers suggest that the distribution of dark matter in the Milky Way produced solutions in general relativity that would, theoretically, allow a wormholes to arise.
Wormholes were first conceptualized by Albert Einstein and Nathan Rosen in 1935. Far from being fodder for science fiction, the two scientists instead proposed their idea as a way to get around the idea of black hole singularities. Rather than creating a knot of infinite density, Einstein and Rosen thought, the hefty energy inherent in such a massive body would distort spacetime to such an extent that it isbent over on itself, allowing a bridge to form between two distant areas of the Universe. Alas, these wormholes would be extremely unstable and would require enormous amounts of “negative energy” to remain open. Quantum fields could be a possible source to this energy according to J. Wheeler. The absence of quantum energies at large scale universe, however, pushes us to rely entirely on dark matter source which proved to be a reality in a recent times.
Before that Salucci mention that their theories are not definitive proof of a wormhole in the Milky Way. Nevertheless, their mathematical models show it is possible thanks to one factor: dark matter. Before that Salucci’s group also show that the possibility of wormholes in the center/outer halos of Milky Way (paper of Rahaman et al. )http://arxiv.org/abs/1501.00490 ).
Now, the physicists from Cyprus have found similar results related to other group’s paper.( arXiv:1509.01237)
According to Einstein’s theory of General Relativity, wormholes allowing travel through time, space or different universes are possible. But until now, most scientists have dismissed the idea of ever building one large and stable enough to pass through, and no natural examples have been detected.
According to the authors, the black hole — a region of concentrated gravity that distorts space-time — may actually be a wormhole in disguise.
Scientists believe that dark matter, together with its big brother dark energy, constitutes roughly 95.8 percent of everything in the universe. That being said, they don’t know much more about it. It’s a substance that lives up to its name, in that it does not absorb, emit, or reflect any kind of electromagnetic radiation, like light. So we cannot see it in any way, but researchers are confident it exists because they can detect the gravity it exerts on galaxies like our own Milky Way. Much like barking of a dog in the backyard that we hear but we do not see the dog.
“Our result is important because it confirms the possible existence of wormholes in most of the outer halos of spherical stellar systems ,” Halilsoy and Ovgun concluded.
