Stephen Hawking thought black holes were 'hairy'. New study suggests he was right.

The outer edges of a black hole might be "fuzzy" instead of neat and smooth.

  • A recent study analyzed observations of gravitational waves, first observed in 2015.
  • The data suggests, according to the researchers, that black holes aren't bounded by smooth event horizons, but rather by a sort of quantum fuzz, which would fit with the idea of Hawking radiation.
  • If confirmed, the findings could help scientists better understand how general relativity fits with quantum mechanics.

Has a black hole made of sound confirmed Hawking radiation?

One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole."

  • Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
  • Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
  • A scientist has built a black hole analogue based on sound instead of light.

No Planet B can 'ever' be made as comfortable as Earth, says British astronomer Martin Rees

The end of the world is the main focus of his new book.

  • Everybody from Elon Musk to Stephen Hawking has said we should colonize a 'Planet B' due to the threat to our existence. Martin Brees, the UK's Astronomer Royal, has another perspective on it.
  • "I think we have to accept that there's no planet B, which can ever be made as comfortable as the Earth," he recently told The Current's Anna Maria Tremonti.
  • In a time of ever-worsening climate change that threatens the very existence of human beings, his focus is on maintaining and fixing the planet we now live on, but still with an eye toward the stars.
