$\begingroup$ Let's address the physics problems in order that they appear: 1) Spacetime can expand at any rate, there is no limit on it. 2) Lightspeed does not require light, it is a speed that any massless information can travel at. The name is just a name. 3) time is part of spacetime. If we say spacetime expands, we have already accounted for any time dilation. However, spacetime expansion does not generate time dilation as it does not actually move. 4) Yes, there were laws of physics in every epoch because however the universe behaved is by definition the laws of physics. Continued.... $\endgroup$

$\begingroup$ 5) No, not all quantum metrics are derived from the speed of light. 6) The rate of inflation is not a velocity, so it cannot be said to exceed the speed of light any more than the pitch of a note can exceed it. 7) A theoretical time zero would be just that. There cannot be a theoretical "before time zero". 8) "Time one" is a meaningless statement. Without units, it could mean now or $10^{-100}s$ after time zero. There is no smallest unit of time. 9) If you are going to conject a timeline, try to make it one that you don't immediately contradict and falsify in your own theory $\endgroup$
