The scale of time

A few days back I mentioned this link which demonstrated the physical scale of things in the universe from the very very tiny to the huge on a cosmological scale. Se /589217_scale_of_universe_enhanced.swf .

Now this got me wondering about the real nature of time. We think of time as running at a constant rate, although relativity suggests this is not true. We happen to be human beings on a certain physical size scale and to us time goes, more or less, at the speed we are used to. What if time itself was somehow as strange as the physical scale of the universe and ran at rates so divergent that a second of our time was almost an infinity for some things in the multiverses? That our concept of time could be akin to the flat-earther's incomplete view of a multi-dimensional world?

What I'm saying is our concept of physical size and time flow is just how it is for us. One can imagine other universes where time runs incredibly fast or incredibly slowly. Is it really so odd to think that we are just a sub-atomic particle in another universe, or that other entire universes both in all space and time are contained within each sub-atomic particle that makes us and every other bit of star dust?

I'm finding it hard to put into words the sort of concepts going through my head, but in summary I think the whole nature of space and time is far more of a wonder and a mystery than we think or can ever imagine.
