How many moments go into a lightyear?

A few years ago, in a TSK retreat given by Jack and Leslie, Leslie asked me: Why do you think that Rinpoche put Time into Time, Space and Knowledge? Why not only Space and Knowledge?

I still like this question! I know that one way to describe reality in the Nyingma tradition is that it is made of the components emptiness and cognizance, sometimes pictured as a blue sky with a sun. Or put differently, Space and Knowledge. If these seem enough to understand reality traditionally, why Time?

Doing a lot of time exercises and looking at the simple line diagrams, like the one in ex 14 of LOK to explain what a moment is, I wonder: Maybe Time is also Space, but a special space. Namely the allowing of Space to make a space. Then you have a presentation. Something you can count and cumulate, use to build a reality and by doing so a self. Maybe Time is the allowing of space that there can be a self although at the same time there is none. Instead of: really , there is none.Without Time it might be difficult to have something funky, either in the musical or smelly connotation.

Still, using the exercises, Time opens and expands, and there are moments between moment (all connotations that can also be used when talking of Space).

If you can describe a distance by how long something takes, for example the distance light travels in a year time, can you also describe a moment as a place by how much space it takes? And if the space expands and condenses in that place does the moment do the same? Can Space go by?
