Why Are Neutron Stars So Incredibly Dense?

💡 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.
