So you're saying the presence of matter (or mass) does effect the passage of time? A massive, dense planet would spin slower (not because of friction) because it's mass slows the passage of time around it? To anybody inside the gravitational field of the planet, it would appear to spin at a normal, unaffected speed, because time would be slowed for that observer as well. But the further the observer is from the massive planet, the more they're able to notice the slowing of time? So I think density is only related to this phenomena in that the denser the mass, the more concentrated the distortion of time becomes. A planet with equal mass but 1/3 the density would distort time by 1/3 as much, but over 3x a larger area. So the net distortion of time stays constant.
Assuming this is all correct.. A universe with zero mass would experience time infinitely quickly. Basically, there would be no time. And a universe with infinite mass (and density) would experience time infinitely slowly. Again, there would be no time.
Strange, the only other thing I know of that effects the passage of time is speed. Maybe mass and velocity are related somehow? Anyway, sort of off topic, but interesting none the less. Maybe I'm completely off track :D
