First This is not a nuclear question... and I am not a physicist ... My question concerns the age of ALL atoms in the universe... From the big bang to now we are talking 15-16 BILLION years???... And looking at the galaxies and how many light years they are away from us, we (our atoms) are all extremely OLD.... SO how is it that Atoms can maintain an endless energy level.... Active Electrons, Neutrons, Protons... I would think all atoms would be dead (out of energy) at this age point (billions of years)... Where does all that energy come from and why has it not run out?
