Einstein said that all time exists now both the past and present. But in Quantum Atom Theory time is created by atom expansion in block of energy (quanta) that grow and create their own spacetime. Like a small child putting square play blocks on top of each other spacetime is formed in the same way.
Today physicists say the microscopic world is very different from ours and that they need probability wavefunctions because there can only ever be a probability of where things might be.
But in QAT when we look at the microscopic world of the atom we are looking at the future of that atom own spacetime and the probability is no different than you would get with any future event. I could set up a probability wavefunction for myself to find out where I might be tomorrow and it would work for me just as good as it works for an electron.
