What are the constraints (if there are any) placed on time by the different theories in the standard model and what are their potential implications?
sunrah said:Hi, yes I realize that. I should have phrased the question more accurately. I meant qualitatively, how do the different areas of standard physics like relativity, thermodynamics, QFT (I haven't studied this last one) etc. treat time and how may we interpret this sensibly. Time is after all common to all of areas in physics, I think.
anorlunda said:That is still very unclear. I don't understand what you are asking.
It may be that you are interested in the causal structure of relativity. You may want to start with the section labeled Causal Structure here:sunrah said:It seems question the notion of a well defined past, present and future
The standard model of time is a theoretical framework used to explain the behavior of time and its relation to other fundamental forces in physics. It is based on the principles of special relativity and quantum mechanics.
The standard model does not provide a definitive explanation for the flow of time. It describes time as a dimension in which events occur and can be measured, but it does not offer a fundamental understanding of why time moves in a certain direction.
The standard model does not explicitly rule out the possibility of time travel, but it does suggest that it would require extreme conditions and energy to achieve. It also raises questions about the causality and consistency of time travel.
The standard model does not account for the subjective experience of time, such as how time may seem to pass at different rates for different people. This is still an area of ongoing research and debate in physics.
Like any scientific theory, the standard model of time is subject to ongoing research and refinement. There are still many unanswered questions and potential limitations, such as its inability to fully integrate with general relativity and the lack of a complete understanding of the nature of time itself.
