scaling - Characteristic length, characteristic time and complexity of the process

Different physical processed (starting from elementary particles or even below to the universe itself) have different length scales $L$ and different characteristic times $T$. Larger processed tend to live at slower pace (very roughly, for electron orbitals it is $(10^{-10}\text{m},10^{-15}\text{s})$ while for stars - $(10^{11}\text{m},10^{12}\text{s})$).

But going into details, objects of the same size have different characteristic times. For example, a human time scale (from 'blink of an eye' (100ms) to the lifespan (70ys)) is much shorter that for a rock of the same size.

The question is if such relation (i.e. $T$ vs. $L$) is related to complexity of a process (either in terms of precision/robustness of it, long range correlations, or structure of interactions between its components)?

Any 2D plot of "time scale" vs "length scale" of different processed would be appreciated.
