After all, we're all doing a version of it as we read the TML - away from the Big Bang, at 1 second per second. So a trivial answer to your question would be "Yes - don't even need to power it up". Are you creating a closed timelike curve and sending some other poor sod down it? Are you creating _and traversing_ a CTC, like Thomas Jones-Low's reply seemed to assume? Are you bolting a modified DeLorean to your Scout ship and *BAMF*ing further away from the Big Bang - discontinuous travel in all of x, y, z and t, simultaneously, where t1 > t0? There's probably a bunch of cases I've missed, but that should do for a start. Alex
