Did you knowโฆ Every atom in your body is billions of years old ๐คฏ Hydrogen, the most common element in the universe and a major feature of your body, was produced in the big bang 13.7bn years ago ๐ณ Your body also has heavier elements like copper and zinc. These atoms were created in the dying stage of an exploding star called a supernova ๐ซ These elements were flung into space as dust and gas (stardust). Eventually, they coalesced to become part of a new forming solar system and our planet Earth ๐ Because you are made from matter from the Earth, you are made of stardust from old supernovas. So turns out, you are bits and pieces of star and cosmic dust โบ๏ธโจ๐ซ HOW COOL IS THAT?
