Why Are Neutron Stars So Incredibly Dense?

šŸ’” The Answer

  • Neutron stars are the collapsed cores of massive stars after a supernova explosion, packing more than the Sun's mass into a city-sized sphere.
  • A single teaspoon of neutron star material would weigh about 10 million tons on Earth, equivalent to a mountain compressed to that size.
  • Their immense density creates gravitational forces so strong that they warp spacetime, causing light to bend around them.
  • Neutron stars rotate extremely fast, some hundreds of times per second, emitting beams of radiation that appear as pulsars from Earth.
