(Newser) – Stephen Hawking helped develop current theories on black holes—but now, he's saying there aren't any. New Scientist explains his thinking, focusing on what's known in physics as the "firewall paradox," which deals with a black hole's event horizon. That's an "invisible boundary" that prevents anything that crosses it from escaping, Nature explains. The theory of general relativity suggests that an astronaut passing through an event horizon wouldn't even notice it. Quantum theory, however, says that an event horizon would be packed with energy—something an astronaut would definitely notice, since she'd be burned alive.

The conflict is known as the "firewall paradox," and Hawking's new theory addresses it. The theory favors "apparent horizons" over event horizons. Apparent horizons hold matter and energy but later release them "in a more garbled form," as Nature puts it. Per Hawking: "The absence of event horizons means that there are no black holes—in the sense of regimes from which light can't escape to infinity."

As my theories have said, "black hole" is a misnomer. As gravity is the consequence of the mutual repulsion of space-time and matter, a "black hole" is merely the highest concentration of matter space-time can tolerate within a given volume. That means a "black hole" has no inside and the diameter of the event horizon grows as the accumulation of matter grows.

What would motivate him to change his mind all the sudden? It couldn't have had anything to do with http://www.simulationism.net/ If you understand what I am arguing you will realize that the clock is ticking, but humanity is probably too stupid to save itself...

From a layman's point of view I can see how black holes can cause theoretical problems. Black holes ultimately require infinite gravity. Nature doesn't do infinity. If it did, then how could anything exist? Evolution, be it biological or astronomical, requires change. Change and infinity are mutually exclusive.
