Penrose's Conformal Cyclic Cosmology

[Etude in B Minor]

One way of looking at it is that there are physical quantities for which time does not matter (or exist) and others for which space does not matter (or exist). An example of the former is a photon. I can't think of an example of the latter. Perhaps a graviton is one (don't know). Time is meaningless for a photon. So infinite times or zero time is irrelevant. At the very earliest stages of the universe and at times far in the future, these are the only type of physical quantities that are present.
