“Gravitational waves will bring us exquisitely accurate maps of black holes – maps of their space-time. Those maps will make it crystal clear whether or not what we’re dealing with are black holes as described by general relativity,” said Nobel Prize laureate, Caltech’s Kip Thorne. Now, scientists at Cardiff University’s Gravity Exploration Institute are using the technologies behind one of the biggest scientific breakthroughs of the century—the detection of gravitational waves led by Thorne— in the long-standing search for dark matter.
“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 hypothesize 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,” explained Paolo Salucci, astrophysicist with SISSA and a dark matter expert. “We could even travel through this tunnel, since, based on our calculations, it could be navigable.” Salucci is among the authors of the paper published in Annals of Physics.
