I repeat:
You cannot possibly chase down and catch light from the rear because there is no such thing as light from the rear! It is single-sided 2-dimensionally flat photo-freeze frame macrocosmically and the same in photon physic both macrocosmically and microcosmically!
Now, as to time, it's a different story altogether which is why it has no back. As a photo-frozen (in time) element of the macro- and micro-cosmic, it is a time reverse descent in time, NOT an equal but opposite time forward ascent. All observers, including travelers, will always have to turn their faces into it and see histories and nothing but histories, descended and/or descending in SPACETIME toward the collapsed cosmological constant of the farthest P/(BC)/(BB) 'Mirror Event Horizon'!
Equally but oppositely, the observer and/or traveler will always ascend forward in time, from that rearward descent, into future histories advancing this way from that same collapsed cosmological constant of the farthest P/(BC)/(BB) 'Mirror Event Horizon'! It will always be a two-way street going and coming at one and the same time creating the cosmological constant "Trojan" of an eternal "standing wave" (c=1 | t=0)!
I know it's bad, and I usually won't do it, but I needed to add on to the above post #807 with additional dimensionality I just re-realized from long ago posting!
Light "is single-sided 2-dimensionally flat photo-freeze frame macrocosmically and the same in photon physic both macrocosmically and microcosmically!" But it pervades the infinities of horizon universes (universe horizons) to an infinite density of faces, an infinite density of singled-sided 2-d facing (only) vectors having no backs to the photo-freeze frames whatsoever and, thus, infinitesimal -- or infinite '0' -- mass and energy.

To turn (universe) is to turn only to a vector facing. It is with a smile
I'm reminded of Stephen Hawking writing in
'A Brief History of Time' of the six sided, six faced, particle that is six different particles. I, immodestly, above, just vastly, just infinitely, enlarged and improved on that conception.
