if you're of the belief that conciousness is a part of our brain and not a supernatural force then this theory may interest you.
consider a chemical reaction between two types of atoms, for example 2 hydrogen atoms and an oxygen atom, every time 3 atoms of these types come into contact they will form a water molecule.
the same is true for any number of any different types of atom, the reaction that takes place between certain atoms will always be the same therefore we can PREDICT the reaction that will take place and the end product.
so say we knew the position of every atom in the universe , its nature and our knowledge of chemical reactions was absolute. we should be able to predict every single reaction and subsequent reaction that will take place in the universe, even the reactions in our own brains, such as the reaction that takes place in response to new information we recieve.
if this theory is true we could predict the future by calculating the reactions, therefore we have an atomic destiny!
please feel free to comment, support or even dismantle my theory!
