Is Our Universe Trapped Inside a Black Hole?
"Is everything we see around us is sealed within a black hole?" asks Space.com. Because here's the thing. The $10 billion James Webb Space telescope (in operation since 2022) "has found that the vast majority of deep space and, thus the early galaxies it has so far observed, are rotating in the same direction. While around two-thirds of galaxies spin clockwise, the other third rotates counter-clockwise." In a random universe, scientists would expect to find 50% of galaxies rotating one way, while the other 50% rotate the other way. This new research suggests there is a preferred direction for galactic rotation... "It is still not clear what causes this to happen, but there are two primary possible explanations," team leader Lior Shamir, associate professor of computer science at the Carl R. Ice College of Engineering, said in a statement. "One explanation is that the universe was born rotating. "That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole. "But if the universe was indeed born rotating, it means that the existing theories about the cosmos are incomplete." Black hole cosmology, also known as "Schwarzschild cosmology," suggests that our observable universe might be the interior of a black hole itself within a larger parent universe. The idea was first introduced by theoretical physicist Raj Kumar Pathria and by mathematician I. J. Good. It presents the idea that the "Schwarzchild radius," better known as the "event horizon," (the boundary from within which nothing can escape a black hole, not even light) is also the horizon of the visible universe. The article cites a theory by Polish theoretical physicist Nikodem Poplawski of the University of New Haven that ultimately black holes don't compress indefinitely into a singularity. "The matter instead reaches a state of finite, extremely large density, stops collapsing, undergoes a bounce like a compressed spring, and starts rapidly expanding," Poplawski explained to Space.com... The scientist continued by adding that rapid recoil after such a big bounce could be what has led to our expanding universe, an event we now refer to as the Big Bang... "I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole." Team leader Shamir offers another theory: that we just need to re-calibrate our distance measurements for the deep universe. (Which could also explain the difference in the expansion rates in the universe "and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.")
