ORIGINAL: kdsub Unless I am mistaken there is no edge of expansion... all matter is moving away from all other matter in all directions at an accelerating rate. This is very hard for me to grasp… where is the cut off in size for this expansion. Butch Well it does have to reflect back on us, imagine if every light particle just floated outside the universe to somewhere forever and ever. It would be a Malthusian place indeed, and there would, at the speed of light, soon be no weight (actually mass though) to hold this bitch together, (moon: hit the ironicator) and thats about how that would work for us. Galaxies are not one sided. We only gather the photons coming our way. Other photons emitted by distant galaxies must be heading out into the void, I would think, ahead of the outward rushing stars. So, beep, beep! If they leave this universe, we are losing mass, that dont bode well for those who won't play dice. Who is to say it is everlasting? Maybe it will go out with a whimper. As I understand it the amount of mass/energy that we can detect is insignificant. Less than 1.0% of the total. So, the loss may be just a tiny leak in the dike.
