Report Abusive Post Report Copyright Violation | Lab-grown black hole analog behaves just like Stephen Hawking said it would So with this information is it possible that our sun is an inverted black hole as that video many of us had seen a bit back suggests? Makes me wonder. In 1974, Stephen Hawking theorized that the universe's darkest gravitational behemoths, black holes, were not the pitch-black star swallowers astronomers imagined, but they spontaneously emitted light — a phenomenon now dubbed Hawking radiation. The problem is, no astronomer has ever observed Hawking's mysterious radiation, and because it is predicted to be very dim, they may never will. Which is why scientists today are creating their own black holes. Researchers at the Technion-Israel Institute of Technology did just that. They created a black hole analog out of a few thousand atoms. They were trying to confirm two of Hawking's most important predictions, that Hawking radiation arises from nothing and that it does not change in intensity over time, meaning it's stationary.

It made me think of that movie. It was the last in a series on Amazon prime. Maybe you're just paranoid, pudders. |

Sigh... this thread is like monkeys trying to talk about quantum mechanics. Hawking Radiation originates from the virtual particle pairs generated right at the event horizon. Usually these pairs are generated all the time and everywhere, but they exist only for the Planck-time before they self-annihilate. They exist for such a short time (and on "borrowed energy") that they don't really exist in a causal way. That's why they are virtual particles. However, at the event horizon, one of the particles may fall into the black hole, which leaves its pair outside the black hole as a real particle. It may annihilate with a nearby anti-particle or produce radiation as it orbits the black hole at relativistic speed. That is Hawking Radiation. Hawking Radiation is in the infrared spectrum, because the original gamma/x-rays become red-shifted by the immense gravity of the black hole. |
