Dimension Space was first a point, and Dimension Time was first a moment, so the first expression of 'the Universe' was point-moment. When God commanded 'Light be' the continuous expressing of point-moment may have been running for some growing amount of 'zero point field' and the expression of electro-magnetic phenomena would have been rather profound since the 'collisions' would produce 'things' much larger than all the point-moments around before the expression of electro-magnetic 'things'. IOW, the 'BANG' is continuing because God The Creator has not yet halted the expressing of lots of 'point-moment'.
The volume of Space-Time is full of point-moment and continuing to grow. With the advent of many 'things' formed in this volume, many more complex expressions of Dimension Space have appeared, and many more expressions of Dimension Time have appeared, but we are Created in such a fashion as we cannot sense the 'more complex' expressions of Time but we can sense the more complex expressions of Space because we sense linear, planar, and volume (length, width, and height, for those in Rio Linda). For reference, a photon only senses length or libear Space.
There is planar time and volumetric time, but we only occasionally confront these, as in the Fifth Chapter of Daniel, or Jesus exiting the tomb or appearing and disappearing from the Upper Room, or passing through the throng who sought to take Him and stone Him, His appearances inthe Old Testament.
Next to last word in third paragraph should be linear, not libear. Small keyboard tiny screen. UGH!
