Hi ISDAMan, What it does do, in 3D, is account for the perception of greater expansion speed as you observe at greater distances from our point in space. I understand what you mean, but the comparison with a wave is not sufficient to explain why distant galaxies are receding from us faster than closer ones. If you are on that supersonic wave (to call it that way), then you're moving at a constant speed (there is no reason why the "cause" of the waves would accelerate). Waves propogate at a constant speed throughout the same medium (in this case ether), hence the total speed you would observe of all the waves is your speed + wave speed. This is an addition of constants, hence the result is also constant. Even if it does rotate for some amount of time, why wouln't it stop? The forces within have to be outstanding. The rotation would have to stop at a certain point (because loads of kinetic energy gets lost through collisions - friction). All this friction causes the whole thing to heat up again, but what happens afterwards is a mystery to me. (My guess is that the heating of the collapsing universe would cause it to rotate more rapidly, since systems tend to have as much entropy & kinetic energy as possible. But somehow I feel this isn't applicable in this case... Guess it's about time I get those thermodynamics courses Please Register or Log in to view the hidden image!). Bye!
