Black Hole Facts



  • Black holes are places where gravity is so strong that it sucks everything in, including light.
  • If you fell into a black hole you’d stretch like spaghetti.
  • Black holes form when a star or galaxy gets so dense that it collapses under the pull of its own gravity.
  • Black holes may exist at the heart of every galaxy.
  • Gravity shrinks a black hole to an unimaginably small point called a singularity.
  • Around a singularity, gravity is so intense that space-time is bent into a funnel.
  • Matter spiralling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the Universe – quasars.
  • The swirling gases around a black hole turn it into an electrical generator, making it spout jets of electricity billions of kilometres out into space.
  • The opposite of black holes may be white holes which spray out matter and light like fountains.
