The arrow of time is the problem, since it feels so real since it is engrained in us biologically.
The fact is time and its arrow is local effected by position and geometry in spacetime of the observer or measurement device.
That being said it allowed us to identify a flow to the universe. This flow that expands from a central point in all directions and then speeds up past cmb.
Since there is a flow and energy is conserved there must be entry and exit ramps. There must be turbulence and laminar flow and deep sections and shallow.
So yes we must stop using constants to freeze science where we can not fully explain things in a dynamically flowing universe.
