The British physicist revised his theory about black holes and now denies their very existence.
In a new study published on January 22, Hawking puts into question the notion of the so-called event horizon, the invisible border from which nothing can escape a black hole, not even Light.
“The absence of event horizons mean that there are no black holes — in the sense of regimes from which light can’t escape to infinity,” Hawking told Nature.
Instead, he suspects the existence of “apparent horizons,” which captures temporary matter and energy before dissolving them into space.
“There are however apparent horizons which persist for a period of time. This suggests that black holes should be redefined as metastable bound states of the gravitational field.”
“There is no escape from a black hole in classical theory.” Quantum theory, he says, “enables energy and information to escape from a black hole.”
Hawking’s article stems from a scientific talk conducted via Skype at the Kavli Institute for Theoretical Physics in Santa Barbara, California, in August 2013.
