Milky Way could host a huge bridge in space-time. At least, that’s what the
authors of a recent study have suggested. According to the group, teamwork
between Indian, Italian, North American scientists and scientists from other
countries at the International School for Advanced Studies (SISSA) in Italy.
The central disk of Milky Way may host the
necessary dark matter to support the formation and nourishment of a “stable and
controllable” tunnel to a distant section of space-time –known as a wormhole.
The group’s study was issued in the November 2014 issue of Annals of Physics.A pre-print of this research paper is also available at arxiv.org.
(also known as Einstein- Rosen Bridge) were first theorized by Albert Einstein
and Nathan Rosen in 1935. Albert Einstein and Nathan Rosen suggested their idea
as a way to get around the notion of black hole singularities. Rather than
making a knot of infinite density, Einstein and Rosen believed, the immense
energy inherent in such a huge body would twist space-time to such a degree
that it bent over on itself, permitting a bridge to generate between two
detached regions of the Universe. Unfortunately, these wormholes would be
tremendously unstable and would need huge amounts of “negative energy” to stay
according to the research group at SISSA, huge amounts of dark matter could
deliver this required fuel. By means of a model of dark matter’s richness that

established that the scattering of dark matter in the Milky Way produced
explanations in general relativity that would, hypothetically, permit a stable
wormhole to arise. Paulo Salucci, an astrophysicist on the group from SISSA,
described: “If we combine the map of the dark matter in the Milky Way with the
most recent Big Bang model to explain the universe and we hypothesis the
existence of space-time tunnels, what we get is that our galaxy could really
contain one of these tunnels, and that the tunnel could even be the size of the
galaxy itself. But there’s more. We could even travel through this tunnel,
since, based on our calculations, it could be navigable. Just like the one
we’ve all seen in the film Interstellar.” Obviously, Salucci and the
other scientists were working on this task long before Interstellar was released,
but their outcome does provide some theoretical backing to the concepts in the
film – concepts that were also fact-tested and reviewed by physics guru Kip
Thorne of Caltech.
of this research paper consider that their result strengthens the significance
of discerning the accurate nature of dark matter. According to Salucci, “Dark
matter may be ‘another dimension’, maybe even a main galactic passage system.
In any case, we really need to start asking ourselves what it actually is.”
Salucci continued, “Obviously we’re not claiming that our galaxy is definitely
a wormhole, but simply that, according to theoretical models, this hypothesis
is a possibility.” The scientists went on to describe that their notion could
be verified experimentally by relating our own Milky Way, a spiral galaxy, with
a neighboring galaxy of a different type. By equating the dark matter
dispersals between the two galaxies, researchers would possibly be able to use
general relativity to probe variances in their space-time dynamics.
The research was published in 2014 but more and new explanations and statements have been made by the authors of the research.
