Time for Mass

[bandwraith at aol.com]

Sounds like a quote from a visiting prof at Candlebrow...

And what about the question, What is time? Müller says that "I don't
think that anyone will ever have a final answer, but we know a bit more
about its properties. Time is physical as soon as there is one massive
particle, but it definitely is something that doesn't require more than
one massive particle for its existence. We know that a massless
particle, like a photon, is not sufficient."
