Lines: 10 From: Alan WexelblatThanks to those who replied to my earlier posting on time-travel. One thing still puzzles me though: Is it the case that the center of mass of the universe doesn't move? Is is (theoretically) possible to calculate our position/velocity w.r.t. this non-moving point? People seem to talk about our universe as expanding, but exapanding away from what? --Alan Wexelblat WEX@MCC.ARPA
