The Reason Why the Universe Is Not Sucked Into Black Holes

Black holes are sometimes called “the ultimate monster of the cosmos”—an In. They formed when the density of matter in the Universe was at its highest—and thus, they become very dangerous for any object in their vicinity. Black holes are thought to be created when massive stars die in violent explosions known as supernovae. But despite their seemingly unending hunger for matter, black holes do have one interesting property—they can trap light!

Given their ability to swallow anything near them, we can wonder what stops them from swallowing the entire Universe in time. As it appears, researchers have asked the same question, and they came up with a response for it.

Physicist Leonard Susskind from Stanford University is known for his contributions to the string theory. However, besides that, he also dedicated another series of papers to black holes. The key seems to rely on the fact the black holes ultimately expand inward, not out.

“I think it’s a very, very interesting question whether the cosmological growth of space is connected to the growth of some kind of complexit. And whether the cosmic clock, the evolution of the Universe, is connected with the evolution of complexity. There, I don’t know the answer,” explained physicist Leonard Susskind.

His theory is a bit difficult to explain but very interesting nonetheless. If we were to imagine a rubber sheet as a visual representation of spaces dimensions, the way in which the geometry of spacetime is distorted would be similar to the dimples created by a heavy object on the rubber. This creates some sort of gravity tunnel, stretching downward and not as much outward.

The explanation bends the common rules of physics, but Susskind believes that the volume of a black hole can only be explained by looking at its quantum twists. Those who want to learn more can access his online lectures on this topic.
