Supernova and Black Holes | GCSE Physics Practice
Massive stars end their lives in spectacular explosions, creating the heaviest elements in the universe.
Where did the iron in your blood originally come from?
What is Supernova and Black Holes | Practice?
"A supernova is the explosion of a star; a black hole is a region of spacetime where gravity is so strong that nothing, including light, has enough energy to escape."
The End of Massive Stars
Supernova: A massive explosion that distributes elements across the galaxy.
Elements heavier than iron are ONLY formed during a supernova.
Neutron Star: An extremely dense remnant of a massive star.
Black Hole: A region where gravity is so strong that even light cannot escape.
Origin Story: Every atom in your body (heavier than Hydrogen) was once forged inside a star or a supernova!
