Hi all, This has been going on for about a month now after seeing a recent episode of Andromeda. There was a huge explosion in space, (believe a worm hole being blown up) The force from the explosion rocked the Andromeda as they tried to escape the impending blast wave so to speak. My wife insists this is impossible, as there is only a vacuum in space, and you need oxygen to create a force from the blast. I disagree, as energy from a blast, or say a supernova, could send out energy waves for lack of a better word, that would impact, and in turn push said space vessel. Any takers on an explanation? I know, total geek stuff, but hey, who isn't nowadays.
