Theorist was talking about time travel and escape from black holes in his conversation with Bruce just a bit below this post.

By the way, I'm sure theorist understands how what he was describing fits in with the nature of the photon, inverse mapping, cosmological time separation- and time travel in the S7 concept.

Spin/non-spin relate to cosmic reality vs the 4-D cosmos we observe.

From our frame, the universe had a beginning and will have an end- just as we experience same. Cosmologically it is a whole different ball game.
