here, when discussing the second jump, that the Others must have originated even earlier but now I doubt it.
Joelle the holothete does hypothesize that life-bearing planets had coalesced in a nebula even earlier than this pre-galactic phase and that some of that life had become the Others who would have traveled into their future to construct the T machine near the blue star at which Chinook has arrived.
However, the Others can travel into their past as well as into their future. After all, Chinook has traveled into her past to arrive where and when she now is. Surely all life, including the Others, is more likely to have evolved later?
