When a star explodes, the pressure, temperature, and sheer violence are mind-numbing in their power. The conditions are so extreme that atoms flying outward can be slammed together so hard they fuse to form new, heavier elements. Iron, calcium, even gold are all formed in this process. - etesien

The explosion itself scatters these newly-born elements into the Universe, where they mingle with gas clouds while simultaneously compressing those clouds. This causes those clouds to collapse... and form new stars. From such a process our own star was born, and with it the planets. And those heavy elements - processed over and again countless times through various living beings that evolved on our planet - eventually became a part of you. - etesien

Congratulations! You are literally one with the Universe. - etesien
