Why wouldn't the Big Rip destroy photons?

    If the expansion of the universe will eventually rip everything apart, why are photons exempt from this dark energy?

    "Their answer is that the eventual, phenomenal pace would overwhelm the normal, trusted effects of gravity right down to the local level. Even the nuclear forces that bind things in the subatomic world will cease to be effective.

    "The expansion becomes so fast that it literally rips apart all bound objects," Caldwell explained in a telephone interview. "It rips apart clusters of galaxies. It rips apart stars. It rips apart planets and solar systems. And it eventually rips apart all matter."

    This question has already been answered. Photons are fundamental---and they're not matter.
