For long time the nature of spacetime had been the subject of debate, here another version will be discussed in the form of space and time fields where a new concept of energy constraining can explain the interactions between those fields. This model comes in three parts: energy constraining, where the evolution of the quanton fields and their different transitions are discussed, the second part, energy fields, their degrees of freedom and the third part: electromagnetic waves as relativistic quantons and the generic form of Maxwell quations in terms of space and time fields. This work links many of the physical phenomena back to the quanton based world.
