Interesting.
Seems to this layman . . . given that there clearly IS SOME sort of time in Heaven per the Heavenly visitors who’ve returned to tell about conditions there . . .
that is . . . things do not ALL HAPPEN AT ONCE. There is SOME sort of linearity of a time sort . . .
Yet Heaven’s time is clearly NOT OURS. Evidently ‘days’ spent there can equal minutes here or some such.
Perhaps the fellow is discerning some keen reality.
Cumrun Vafa and P.S. Wesson have led the way on multiple temporal dimensions. In Vafa's as in the one above, it is an extension of the Kaluza/Klein compactified model. In Wesson's the extra dimension (5 dimensions, 2 time) is expanded, i.e. a higher dimension.
The Creator's perspective - uncaused cause of space/time/physical causality etc. - is timelessness and spacelessness.
(C.S. Lewis reference...)
Oh goodie! That blows Genesis out of the water, at least the "6 days are 6 days" version. Why not a billion-year day? NOT sarcasm.
