Now is a simple yet elusive concept.
You are reading the word now right now. But what does that mean? What makes the ephemeral moment now so special? Its enigmatic character has bedeviled philosophers priests and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity yet he despaired at his failure to explain the meaning of now. Equally puzzling: why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion but the eminent experimentalist physicist Richard A. Muller protests. He says physics should explain reality not deny it.
In Now Muller does more than poke holes in past ideas; he crafts his own revolutionary theory one that makes testable predictions. He begins by laying outwith the refreshing clarity that made Physics for Future Presidents so successfula firm and remarkably clear explanation of the physics building blocks of his theory: relativity?? entropy?? entanglement?? antimatter?? and the Big Bang. With the stage then set?? he reveals a startling way forward.
Muller points out that the standard Big Bang theory explains the ongoing expansion of the universe as the continuous creation of new space. He argues that time is also e
