Ep 43: Pop go the stars

Pop go the stars

For our universe to produce minds, we require many different chemical elements. Those elements were created by the stars. The lighter elements fuse together and provide the energy for stars to shine, and to keep from collapsing under their own gravity. Heavier elements, anything heavier than iron, require the stars to go pop—to explode into super novas which create the rest of the heavy elements.

Here’s a page on Nucleosynthesis, the process that created the chemical elements that make up our planet, and us.
