It's hard to find pieces of work on time particles. There isn't much on it because not much research has been done, but it's a key factor to the entire Big Bang/Bounce theory.
Quote:
Einstein’s great insight was that spacetime is no mere stage on which the drama of the universe unfolds. It is an actor in its own right.

Quote:
The spacetime atoms form a dense, ever shifting mesh. Over large distances, their dynamism gives rise to the evolving universe of classical general relativity. Under ordinary conditions, we never notice the existence of these spacetime atoms; the mesh spacing is so tight that it looks like a continuum. But when spacetime is packed with energy, as it was at the big bang, the fine structure of spacetime becomes a factor, and the predictions of loop gravity diverge from those of general relativity.
