Being be’s… not-being be’s-not. –Parmenides
In a new paper, physicists Ahmed Farag Ali, Mir Faizal, and Barun Majunder have shown that, according to a new generalization of Einstein’s theory of gravity called “gravity’s rainbow,” it is not possible to define the position of the event horizon with arbitrary precision. If the event horizon can’t be defined, then the black hole itself effectively does not exist.
“In gravity’s rainbow, space does not exist below a certain minimum length, and time does not exist below a certain minimum time interval,” Ali, a physicist at the Zewail City of Science and Technology and Benha University, both in Egypt, told Phys.org. “So, all objects existing in space and occurring at a time do not exist below that length and time interval [which are associated with the Planck scale]. As the event horizon is a place in space which exists at a point in time, it also does not exist below that scale.”
