‘Hawking radiation’ may be erasing black holes. Watching it happen could reveal new physics. | Live Science

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.

Primordial black holes (PBHs), which are thought to have formed right after the Big Bang, may be heating up and exploding throughout the universe.

These black hole explosions, powered by Hawking radiation — a quantum process where black holes generate particles from the vacuum due to their intense gravitational fields — could be detected by upcoming telescopes, physicists suggest in a new study. And, once spotted, these exotic explosions could reveal whether our universe contains previously undiscovered particles.

If someone had to explain how Japan is going to hell in a hand basket, it would be kindly Arnie Gunderson. This video, one in a series of updates on the Fukushima emergency (and don’t kid yourself, it’s still an emergency), lays out in easy to understand language and examples exactly what is going on.

The fact that Mr. Gunderson has a soothing relaxed presence helps.
