Neutron Stars Are So Dense a Teaspoon Would Weigh 6 Billion Tons
When massive stars collapse, protons and electrons are crushed together into neutrons, creating matter so dense that a sugar-cube-sized piece would weigh about 6 billion tons — roughly the weight of Mount Everest.
Why It’s Fascinating
Neutron stars rotate up to 716 times per second and have magnetic fields a trillion times stronger than Earth's. They represent the absolute limit of matter before it collapses into a black hole — the universe's last stand before the point of no return.

There Are More Stars in the Universe Than Grains of Sand on Earth
Astronomers estimate there are roughly 200 sextillion stars in the observable universe (2 x 10^23). Earth has approximately 7.5 x 10^18 grains of sand, making stars outnumber sand grains by a factor of about 26,000.
