Well one doesnt think to see to see atoms underoing much change out in the vacuum of frozen space , theres not much variety or concentrations out there in any ways , not much to work with . But when you get little planets like our Aubergine going , there's plenty of solutions & things going on in the mix . Elements not even dreamed of in the hearts of a suns are found on Earth Aubergine ....
Within stars certain progression of atomic joinings take place which are limited up to the formation of nickle/iron only , the most stable of all elements in the universe chemically .Atoms just love to be joined together as iron & everything above wants to decay down to it & everything under dreams of becoming it but thats another story .
On planetoids like our Aubergine Earth , as that Indian fellow describes many things are likely to happen because of the nature of molecues themselves that will tend to group for a variety of reasons by the proclivities of chemical bondings .And there are some 30 more elements to work with than found in the sun , those only come into being when certain rarer suns explode in Nova
One sees complexity growing if we were to stop here , but it doesnt stop there obviously when planets get going like our Aubergine that have all the elements present with lunar body ,oceans , tidal effects ,weather, electrical storms , volcanic activity , electromagnetic fields , meteroites & atmospheric gasses, . etc |
