“Singularities don’t exist,” claims black hole pioneer Roy Kerr

Here in our Universe, whenever you gather enough mass together in a small enough volume of space, you’re bound to eventually cross a threshold: where the speed at which you’d need to travel to escape the gravitational pull within that region exceeds the speed of light. Whenever that occurs, it’s inevitable that you’ll form an event horizon around that region, which looks, acts, and behaves exactly like a black hole as seen from the outside. Meanwhile, inside, all that matter gets inexorably drawn towards the central region inside that black hole. With finite amounts of mass compressed to an infinitesimal volume, the existence of a singularity is all but assured. The predictions for what we should observe outside the event horizon match extraordinarily well with observations, as we’ve not only seen many luminous objects in orbit around black holes, but have even now imaged the event horizons of multiple black holes directly. The theorist who laid the foundation for how realistic black holes form in the Universe, Roger Penrose, subsequently <a href="https://www.nobelprize.org/prizes/physics/2020/penrose/facts/" rel="noopener ugc nofollow" target="_blank">won the Nobel Prize in Physics in 2020</a> for his contributions to physics, including for the notion that a singularity must exist at the center of every black hole. <a href="https://medium.com/starts-with-a-bang/singularities-dont-exist-claims-black-hole-pioneer-roy-kerr-8e808f8edd6f">Visit Now</a>
