theories people propose. Obviously the first are those which explain nothing. Yet frankly a theory which claims to explain everything is also bad, particularly if in the case of Tegmark it turns out to be perfectly "safe." It will be a huge challenge as it is to get a few data points or data sets on string theory. Perhaps Universal time is an unfortunate choice of name.How about from now on I call it Positional time? It is position along the 4th dimension ie. Universal potential energy level that can be translated as "position in time" for each object or particle.If the 4th dimension is considered a scale of time, rather than space or energy level.

Universal potential energy level that can be translated as "position in time" for each object or particle.If the 4th dimension is considered a scale of time, rather than space or energy level. Each object and particle is constantly changing 4th dimensional position, that is there is continuous change in Universal potential energy level. Positional time is related to objective reality because it involves position in space or energy level whichever way you wish to interpret it.Potential energy fluctuation or change in 4th dimensional position. Historical time is purely imaginary.The past and future do not have a material existence. They only exist within the mind. The past is memories
