A certain space can be covered by energy moving in either particle or wave form in a certain time assuming a specific velocity virtually anywhere in the time-space universe.
“The causal relationship between events breaks down; movements become jerky rather than smooth. Time and space may become " grainy” or " chunky . Perhaps a piece of space can be traversed by a particle of matter in any direction without necessarily being synchronized with a piece of time. In short, a pair of events will occur in either time or space, the pair not being connected causally but by a random fluctuation."
