Quantum Physics was thrown in, which made Einstein gag. To others, it is god. The Nobel winner, Ilya Prigogene however said QP was, at best, an incomplete theory . Everything in QP is conceived , never observed . And everything is conceived to be reversible .
Events produce particles which supposedly survive for only fractions of a second.
QP events are conceived as virtual and produce virtual particles. These virtual particles do not exist, even in the mind of the quantum physicist . They typically exist only as mathematical tricks. It is fine to use mathematical tricks as computational aids. It is absurd to pretend that these exercises represent reality.
