Here’s a shocker that is challenging long accepted science – the Big Bang never happened. In fact, not only may there may have been no Big Bang at all–our universe may have come from an entirely different source. And as a result, “Cosmology’s greatest challenge is understanding the before, after and whether there even was a Big Bang!” In fact, one physicist says,  astronomers say that the “Universe must have begun with a Big Bang — but that is just a mirage!” The new theory suggests that the universe might actually be the result that the Universe was created when a star in 4 D collapsed into a Black Hole – an insanely huge black hole the likes of which we can’t even imagine. The publication Nature says that:

In a paper posted last week on the arXiv preprint server, Afshordi and his colleagues turn their attention to a proposal2 made in 2000 by a team including Gia Dvali, a physicist now at the Ludwig Maximilians University in Munich, Germany. In that model, our three-dimensional (3D) Universe is a membrane, or brane, that floats through a ‘bulk universe’ that has four spatial dimensions.

Ashford’s team realized that if the bulk universe contained its own four-dimensional (4D) stars, some of them could collapse, forming 4D black holes in the same way that massive stars in our Universe do: they explode as supernovae, violently ejecting their outer layers, while their inner layers collapse into a black hole.

In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object — a shape called a hypersphere. When Afshordi’s team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand.

The authors postulate that the 3D Universe we live in might be just such a brane — and that we detect the brane’s growth as cosmic expansion. “Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang — but that is just a mirage,” says Afshordi.

The Big Bang has never been fully explained

The Big Bang has never been fully explained and in fact, the biggest question is “WHAT CAUSED IT TO HAPPEN?” What caused the Big Bang cataclysmic event – the one that blasted our universe into existence 13.7 billion years ago?  before the big bang. It’s a bit perplexing, but it is grounded in sound mathematics and is it testable?

What we perceive as the big bang, Three Perimeter Institute researchers argue, could be the three-dimensional “mirage” of a collapsing star in a universe profoundly different than our own.”Cosmology’s greatest challenge is understanding the big bang itself,” write Perimeter Institute Associate Faculty member Niayesh Afshordi, Affiliate Faculty member and University of Waterloo professor Robert Mann, and PhD student Razieh Pourhasan. Conventional understanding holds that the big bang began with a singularity — an unfathomably hot and dense phenomenon of spacetime where the standard laws of physics break down. Singularities are bizarre, and our understanding of them is limited.

“For all physicists know, dragons could have come flying out of the singularity,” Afshordi says in an interview with Nature. The problem, as the authors see it, is that the big bang hypothesis has our relatively comprehensible, uniform, and predictable universe arising from the physics-destroying insanity of a singularity. It seems unlikely. So perhaps something else happened. Perhaps our universe was never singular in the first place.
