That seems to suggest a new study carried out by scientists from the Perimeter Institute for Theoretical Physics (Canada), in tune with the theory of the multiverse or coexistence of multiple universes beyond the observable, this being part of another universe of higher dimensions. According to his conjectures, the Big Bang or great cataclysm that unleashed the expansion of the cosmos, would have simply been the “mirage” projected in a three -dimensional world of the collapse of a star in a four-dimensional universe, which, when it became a black hole, expelled the matter that gave birth to our own Universe.
The Big Bang theory, increasingly evidenced thanks to the recent detection of primordial gravitational waves, although it explains the origin of the Universe, raises a big question: what caused the initial explosion? The standard model of physics says that physics arose from a single hyperdense point, also called a spacetime singularity. However, Canadian scientists find it unlikely that a predictable and uniform universe like ours would emerge from the chaotic destruction of a singularity .
Faced with this hypothesis, the authors of the work affirm that the Universe burst into existence when a star in a four-dimensional universe collapsed into a black hole. In a 3D universe like ours, a black hole is delimited by the “event horizon”, the boundary of which is a two-dimensional object, that is, a surface. In contrast, in a hyperspace universe (4 or more dimensions), the event horizon of a black hole would be a 3D object. By simulating the death of a 4D star, the researchers discovered that the matter ejected in the collapse formed a three-dimensional “brane” around the event horizon, which was expanding very slowly; that would be exactly our cosmos, the residue of a gravitational collapse in a larger universe, spreading in all directions.
The new model, mathematically verifiable according to the researchers, raises such interesting questions as whether each star that collapses into a black hole introjects a new universe or whether there are infinite-dimensional universes , with what this may imply.
