  • Scientists discover that some extreme black holes may violate the "no hair" theorem.
  • These black holes feature properties outside of the three classical black hole traits of mass, spin, and charge.
  • The researchers ran sophisticated simulations to discover these space oddities.

Are we living in a baby universe that looks like a black hole to outsiders?

Baby universes led to black holes and dark matter, proposes a new study.

  • Researchers recently used a huge telescope in Hawaii to study primordial black holes.
  • These black holes might have formed in the early days from baby universes and may be responsible for dark matter.
  • The study also raises the possibility that our own universe may look like a black hole to outside observers.

New data reveals Earth closer to a black hole and is moving 16,000 mph faster

A new study shows our planet is much closer to the supermassive black hole at the galaxy's center than previously estimated.

  • A Japanese radio astronomy project revealed Earth is 2,000 light years closer to the supermassive black hole at the Milky Way's center.
  • The data also showed the planet is moving 7 km/s or 16,000 mph faster in orbit around the Galactic Center.
  • The findings don't mean Earth is in more danger from the black hole but reflect better modeling of the galaxy.

    • Roger Penrose, the 2020 Nobel Prize winner in physics, claims the universe goes through cycles of death and rebirth.
    • According to the scientist, there have been multiple Big Bangs, with more on the way.
    • Penrose claims that black holes hold clues to the existence of previous universes.

    • Scientists prove a 50-year-old physics theory by Roger Penrose.
    • The theory explains how energy could be harvested from black holes by advanced aliens.
    • Researchers from the University of Glasgow twisted sound waves to show that the effect Penrose described is real.
