We have refined our understanding of gravity from being a force of nature that attracts 2 masses, to gravity being merely the curvature of space-time to gravity being interpreted as time slowing down in space.
The other important ongoing discovery has to do with dark matter and dark energy which constitutes around 95% of our observable universe. Commensurate with evolving insights of dark matter and energy, dark energy at least seems to be the omnipresent energy in the vacuum of space, spread out over such large spaces that its detection is faint due to its density being very less.
I imagine, that dark matter may also on similar lines differ from ordinary matter, in that, it is much less dense and spread out over the vast expanse of inter galactic spaces. The current tug of war between our expanding universe v/s gravity, could then be seen as a war of equilibrium between normal matter/energy vs dark matter/energy, and clearly normal matter is getting rarefied, on the overall scale of the universe.
Next, lets for a moment assume that the nature of reality(matter and energy), truly is made up of E8 crystals or any other unit of reality, for that matter. So ordinary matter could be nothing but "densely packed E8 crystals" and dark matter could be "very rarefied" E8 crystals.
Time as we know it, is perceived by us, as beings made up of matter. Our perception of time primarily is from the point of view of how it appears in the "ordinary matter" portion of the universe. In the vacuum of space and in the dark matter part of the universe, is time just as relevant?
The perception of time is linked to causality, as experienced by us in the macro universe.
Time in the macro universe might seem ubiquitous but at sub atomic and quantum scales, where wave nature, duality, uncertainty and randomness are the norm, does the linear flow of time, as in the macro universe even hold relevance?
Time needs a frame of reference and an observer, without these, being clear to us, over the expanse of the universe and dark matter, is time a relevant variable for study, of particle physics itself?
Now can you blame me for tending to think, that time might be an illusion of our perception of the macro universe.
