The Big Bang may be a Big Bogus.

A team of physicists at the University of Portsmouth theorize that the universe was created by a massive, reality-shattering bounce — with material from an ancient black hole.

The scientists are the latest to back the Black Hole Universe theory, which states that the cosmos didn’t just emerge from an explosion of matter rather it rebounded like a basketball bouncing off a rim from something else already existence, according to VICE.

First pitched by Indian physicist Raj Kumar Pathria in the 1970s, the Big Bounce spent decades as a fringe idea, but not anymore.

The theory is centered on the simple but mind-bending idea that inside a black hole, matter compressed to its quantum limit, hit a wall, and snapped back outward like a coiled spring, inflating into the universe as we know it.

And as astronomers now continue to find black holes scattered across the universe, scientists now believe that they may not just be cosmic vacuums, and could actually be serving as a sort of womb that is quietly creating an entirely new universe inside them similarly to ours, the report said.

They’re not alone in taking a sledgehammer to the Big Bang.

Brazilian physicist Juliano Cesar Silva Neves of the University of Campinas argued back in 2017 that the Big Bang never happened at all — and that the universe may have been preceded by a contraction phase, collapsing inward before bouncing back out into the expansion we see today, according to the report.

His research, published in the journal General Relativity and Gravitation, suggests traces of that previous contraction may still be detectable inside the black holes scattered across our universe right now.

Fresh data from the James Webb Space Telescope is now helping to confirm this theory, as a strange imbalance in the spin directions of ancient galaxies was discovered last year, exactly what would be expected if our universe was born spinning, hurled outward from a rotating black hole, according to VICE.
