Could our Galaxy galaxy host a giant wormhole similar the 1 depicted inwards the motion-picture exhibit “Interstellar”? This is the hypothesis position frontward inwards a written report published inwards Annals of Physics. The paper, the lawsuit of a collaboration betwixt Indian, Italian together with North American researchers, prompts scientists to re-think nighttime affair to a greater extent than accurately. “If nosotros combine the map of the nighttime affair inwards the Galaxy amongst the close recent Big Bang model to explicate the universe together with nosotros hypothesise the being of space-time tunnels, what nosotros go is that our galaxy could actually incorporate 1 of these tunnels, together with that the tunnel could fifty-fifty last the size of the galaxy itself. But there’s more”, explains Paolo Salucci, astrophysicist of the International School for Advanced Studies (SISSA) of Trieste inwards Italia together with a nighttime affair expert. “We could fifty-fifty go through this tunnel, since, based on our calculations, it could last navigable. Just similar the 1 we’ve all seen inwards the recent celluloid ‘Interstellar’”. Salucci is amid the authors of the newspaper late published inwards Annals of Physics.
Although space-time tunnels (or wormholes or Einstein-Rosen bridges) possess got exclusively late gained nifty popularity amid Earth cheers to Christopher Nolan’s sci-fi film, they possess got been the focus of astrophysicists’ attending for many years.
“What nosotros tried to create inwards our written report was to solve the real equation that the astrophysicist ‘Murph’ was working on. Clearly nosotros did it long earlier the celluloid came out”, jokes Salucci. “It is, inwards fact, an extremely interesting work for nighttime affair studies”.
“Obviously we’re non claiming that our galaxy is definitely a wormhole, but exactly that, according to theoretical models, this hypothesis is a possibility”. Can it e’er last tested experimentally? “In principle, nosotros could seek out it past times comparing ii galaxies – our galaxy together with another, real closed 1 like, for example, the Magellanic Cloud, but nosotros are soundless real far from whatever actual possibility of making such a comparison”.
To hit their conclusions the astrophysicists combined the equations of full general relativity amongst an extremely detailed map of the distribution of nighttime affair inwards the Milky Way: “the map was 1 nosotros obtained inwards a written report nosotros carried out inwards 2013”, explains Salucci. “Beyond the sci-fi hypothesis, our query is interesting because it proposes a to a greater extent than complex reflection on nighttime matter”.
As Salucci points out, scientists possess got long tried to explicate nighttime affair past times hypothesising the being of a special particle, the neutralino, which, however, has never been identified at CERN or observed inwards the universe.
But option theories also be that don’t rely on the particle, “and mayhap it’s fourth dimension for scientists to takethis number ‘seriously’”, concludes Salucci. “Dark affair may last ‘another dimension’, mayhap fifty-fifty a major galactic carry system. In whatever case, nosotros actually demand to begin shout for ourselves what it is”.
In improver to Salucci, the other scientists who took purpose inwards the written report included Farook Rahaman (first author), from Jadavpur University inwards India, together with a grouping of Indian together with North American researchers.
