Since space time seems to be fuzzy or quantized at the Planck Space and Planck Time scale levels at ~ 10 EXP - 35 meters and 10 EXP - 43 seconds respectively, I wonder whether or not there exists spatial or temporal "hidden variables" below the level of the Planck Distance Scales?

Time is one of the most important and yet is one of the least analyzed concepts of physics. Einstein's one line definition of time is incomplete if not an incorrect description of time.

One of the biggest problems of this definition is that it makes us think on the lines of two events taking place in the universe with some sort of interval between the events.

This is against the basic idea of relativity of time. The 'moment' cannot have a fixed interval.

Time is a continuous, irreversible process that goes on at different pace at different coordinates of space. This process causes even clocks to run faster or slower.

Unforutnately, it is not possible to sum up the process in one post. I have discussed the process in detail on my website www.norlabs.org.
