Drei kosmologische Zeitskalen
Three cosmological scales of time

The time we use to describe microscopic and everyday processes is
atomic time t.
In addition we infer cosmic processes from everyday and atomic physics and find an expansion law a[t]. Cosmological processes propose in certain aspect to use
the conformal time dτ = dt/a[t]
or even a thermodynamic time dθ = dt/a³[t]

There is no end for atomic time, there is no start for thermodynamic time
