What is energy? Where is the energy the Sun produced in the past? Fusion is impossible. Scientists don't know why electron and proton in hydrogen atom don't stick together yet, all theories about atom, matter and energy are BS.
It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way. -Feynman
All these fifty years of conscious brooding have brought me no nearer to the answer to the question, “What are light quanta?” Nowadays every Tom, Dick, and Harry thinks he knows it, but he is mistaken. - Einstein Why electron and proton don't stick together under electrostatic attraction force? What force/mechanism can separate opposite charged particles?
