Over a century ago, a German physicist named Karl Schwarzschild mathematically described what we now recognize as a black hole using equations. He laid the foundation for black hole cosmology, which is also called the Schwarzschild cosmology.
Many years later, in the early 1970s, two scientists, Raj Kumar Pathria and I.J. Good, built upon Schwarzschild’s work and proposed that the Schwarzschild radius—which we now call the event horizon (the boundary of a black hole beyond which nothing can escape) might also act as the boundary of our universe.
Basically, what they meant is that our universe exists inside a black hole that itself resides within a larger universe — sounds insane, right?
Well, here’s something even more insane: A new study based on the findings of the James Webb Telescope suggests that Pathria and Good were right.
