Yes the SW galaxy is bigger than the Milky Way. The MW is between 80,000 and 100,000 ly across. The SW galaxy is 120,000 ly across. I already knew that, and factored it into my equation. Half a year at 100 million times the speed of light, which happens to be the highest number I've seen on any SW site, would only let them cross 0.36% of the Universe. I think that Far, Far away would be 30x that distance which is 10% of the Universe or 15 years of traveling. But it doesn't really matter. Yes, I know that Covenant and Human Slipspace travel is exceedingly slow compared to Hyperspace. If you re-read that post, I never said that I thought Slipspace was faster. Just that they don't seem to have the same problems with stars and such, although they could have the same problems, it hasn't been shown yet.

Research a bit... I have checked out Halopedia, Wookieepedia and Wikipedia. None of them say anything about plasma exploding. Either explain it to me, or do a little research yourself. Water expands into steam when energy is added. Many gases explode because of chemical reactions. Some plasmas like neon plasma are made from inert gases. Just what chemical reactions are going to occur? Nuclear fusion, at temperatures of 10-100 million degrees Celsius, produces plasma. The plasma near the source of the reaction would be millions of degrees Celsius. These temperatures would heat up nearby atoms in the reactor and cause them to ionize into plasma. So you would have 8000 C plasma and 1 million C plasma interacting with each other for a short period of time. One would have a lot more energy than the other. They would NOT explode. There is nothing in Halo or real-life to suggest that either of their plasmas would explode.

So that leaves SW. I looked up plasma on Wookieepedia, and it doesn't say anything to suggest that it would explode.
