MELBOURNE (TIP): The big bang theory may be a myth, as cosmologists have speculated that the universe was created after a star collapsed into a black hole – a theory that helps to explain why it seems to be expanding in all directions. The big bang theory suggests that the universe was created from a single point in the universe but despite years of research, nobody yet knows what triggered the eruption. It also fails to explain why the Universe has an “almost completely uniform temperature.” Researchers said that there does not seem to have been enough time since the birth of the cosmos for it to have reached temperature equilibrium, reported. Astrophysicists from the Perimeter Institute for Theoretical Physics in Waterloo, Canada have released a paper discussing a previous theory out of Germany that posited that the universe is a three-dimensional “membrane” floating through a four-dimensional “bulk universe”.

A bulk universe is a very complicated concept out of string theory that puts forward the idea that space is a plane of infinite dimensions through which other planes of infinite dimensions float. The team claimed that if the “bulk universe” contained four dimensional stars, some of them could collapse and cause black holes in the same way that stars in our universe do – they turn in supernovae, ejecting their outerlayers while their inner layers collapse into the black hole. Black holes in our universe are spherical in shape and possess some kind of “membrane” that keep them that way. These “membranes” are known as “event horizons”. Anything that passes through this event horizon is done for, because the gravitational pull is so great it makes escape impossible. In our universe only a two dimensional object is capable of becoming an event horizon within a black hole, Nature explained. Whereas in a bulk universe, the event horizon of a four dimensional black hole would have to be three dimensional, known as a “hypersphere”. In a nutshell this means that a star floating through a multidimensional plane got sucked into a black hole, half of it got swallowed up and the other half that survived spawned the creation of the universe. The fact that our universe is expanding in all directions could be a sign simply of cosmic expansion, rather than as the origin of the universe itself, the researchers suggest.
