Quantum Definition of Time - The Incredible Truth
Proposition: Time is actually a broken symmetry of uniformity as in a very, probably highest, symmetric (uniform) state, where everything is equal; time does not and cannot exist. Please do not confuse with the T – in quantum mechanics where the operator of time plays a role in the CPT – theorem/ symmetry.
The uniform symmetry breaking must have happened prior to or at:
Which sounds contradictory as it would mean that time existed before it could have existed. That is of course a misconception for two reasons!
Firstly, no time less than 10-43 s is physically relevant! As space and time is fluctuating; therefore it is not possible to distinct between cause and effect, which is exactly what a uniform space-time would be like (opening sentence). Only when that (higher) symmetry is broken time can come into existence.
Secondly, there are two principles of cosmology:
Space is homogeneous and isotropic!
The highest symmetric state, in a space-time that is homogeneous and isotropic, is of course uniform. But in a uniform state of space-time there is no distinction possible as there is no difference. Only when there is tiny shift, then time can be measured and have a meaning.
Remark: We point out, that there is no such thing as time t = 0 s! As no time smaller than 10-43 s is physically relevant! Physics starts when space and time become possible; and they become possible for the first time, when information can be transported from one point of space to another. And no length smaller than 10-35 m is physically relevant! This is a result of the Planck units.
