From what I can tell... and this may be wayyyyy off... all these fundamental particles (quarks, leptons, etc) don't last long in the "real world". That is to say, no matter how much we pick them apart, they fall back together (or reduce to energy) such that they have no value beyond understanding the esoteric properties of the universe.
​
My knowledge of this stuff is limited to reading Brian Greene and others like him, so my question is based not on knowledge but out of interest. I have looked at web sites of people like Julian Barbour and it seems to me that the next big thing in physics might be time, which could affect the premise of your question.
​
Is it possible, or even likely, that we will be able to use the scientific method to understand how time impacts our existence in the same way that relativity and QM have?

As far as I understand it relativity does get at how time impacts our existence. I would love to have better models, though I don't think direct manipulation of time will ever be possible.
​
Actually I was thinking about time in the quantum realm. If they could do that I think it could provide the link between relativity and QM.

Everybody is entitled to my opinion.
