There are no "actual infinites". Look at this. Today is the last day of all days. But tomorrow will be the last day of all days. Therefore infiite past has changed from infinite days to infinite days + one more day. Ergo there cannot be an infinite past. This is Kalams argument of the cosmological argument for a beginning of the universe (very simplified form). The general theory of relativity asserts that time, space, matter, and energy had a beginning. This was confirmed and supported by Wilson and Penzias in finding the bacground ratiation from the beginnning of the universe, as well as COBE, WMAP, the Red Shift, the second thermal law.
I believe there are two dimensions/realms.. 1) this one.. 2) the spiritual dimension..
Time could be an "element" like water,,, gas, liquid, solid..
But in this dimension time being/appearing solid..
Just as there can be "dark" matter/energy in this realm..
There could also be "dark" time.. maybe liquid or even gas.. in a allegorical sense..
How can you talk of these things?.. Allegorically of course..
