What If the Big Bang Wasn’t the Beginning? Research Suggests It May Have Taken Place Inside a Black Hole

Summary
In a new paper published in Physical Review D, researchers have put forward a radical alternative to the idea that the big bang was the start of everything.
They propose that the big bang was not the beginning at all and that, in fact, the universe emerged from something more familiar and radical.
The idea that the big bang was the outcome of a gravitational crunch or collapse forming a very massive black hole was first put forward by Roger Penrose and is known as the black hole universe.
This version of events creates a whole new perspective on our place in the universe and could also provide answers to other deep mysteries.
Among the predictions of this model is a small but non-zero amount of positive spatial curvature meaning that the universe is not flat but slightly curved like the surface of the Earth.
It could also provide an explanation for dark matter and the accelerated expansion of the universe as well as offering a whole new perspective on our place in the cosmos.
Further space missions such as Arrakihs will study diffuse phenomena that are difficult to detect with traditional telescopes and will help scientists to understand dark matter.
