Did you know that all the elements up to Manganese are formed at the center of stars ?
The intense pressure of the star''s gravity causes nuclear fusion which slowly fuses hydrogen into helium, helium into lithium etc. (I''ve simplified this a little)
All of the fusion reactions (pressing the matter together to form larger elements) including the fomation of lithium are exothermic (produce more energy)
BUT!
When the star starts to fuse Manganese into iron, things change !
The formation of iron is endothermic (requires outside energy) this changes the fusion dynamics in the star and causes it to go supernova and explode!
Iron and all of the elements higher than it are created suddenly during the 24 seconds it takes for a star to go supernova.
Stars go supernova in a flat disk shape with the lighter stuff cast out further than the heavier stuff, so when a sloar system forms on the grounds of an old supernova, denser rocky planets are closer to the middle an lighter gaseous planets are on the outside.
Our blood has a high iron content - thus we all had to go through a supernova to get here (or at least our bits did).
Our diamond''s carbon had no trouble forming at the center of a star, but the metal for our jewellery also had to form via supernova.
WOW!!!!
