Do you know why your blood is red? Because it’s got iron in it. Any idea where the iron in your blood came from? A supernova. Let me explain: Stars have lots of gravity. To balance the force of this gravity from crushing a star in on itself, it eats hydrogen and helium. It fuses them together which generates massive outward energy. Well, they don’t have infinite food to eat. As they run out of hydrogen and helium, they start fusing heavier and heavier elements. Eventually they fuse iron into existence in their search for energy. Unfortunately (well, actually very fortunately for us) iron doesn’t release energy from fusion. The moment a star starts fusing iron into existence, a supernova begins. As the outward energy is lost the star collapses resulting in one of the largest explosions you’ll ever survive. That’s because the building blocks that eventually came together to make you, like the iron in your blood, were forged in a supernova.
