Stephen Hawking discovers new black hole theory


Recently, Stephen Hawking, a theoretical physicist, announced that the common theory about black holes may be untrue.

The usual idea about black holes is that once they suck in matter or energy, it stays there forever. Hawking was one of the scientists in discovering this original black hole theory.

Hawking’s new theory says that black holes aren’t an infinite abyss that holds matter and energy forever; they may actually release small amounts of it over time, albeit in a more scrambled form.

“There is no escape from a black hole in classical theory,” said Hawking to Nature magazine. “[Quantum theory] enables energy and information to escape from a black hole.”

Additionally, Hawking’s new theory states that black holes don’t have an event horizon, the place around a black hole that defines the area within nothing should be able to escape the black hole. He states this because the effects and actions around a black hole are too wild and sporadic for a crisp horizon to exist.

According to Hawking’s new theory about black holes without event horizons, there is an “apparent horizon,” where light rays are attempting to get away from the center of the black hole, but are held there.

With this theory, the “apparent horizon” can eventually dissolve when a black hole has shrunk to a small enough size and releases everything it once held.

Although Hawking’s theory is supported by evidence, some physicists are skeptical of his idea.

In an interview with the Scientific American, theoretical physicist Joseph Polchinski is weary of the idea of black holes without event horizons.

“In Einstein’s gravity, the black-hole horizon is not so different from any other part of space,” said Polchinski. “We never see space-time fluctuate in our own neighborhood: it is just too rare on large scales.”

Even years after Hawking’s first black hole theory, physicists are still discussing the basic questions of black holes, just showing how much of a mystery these cosmic abysses are.
