[quote=@SimplyJohn] The door's over there and I think Simon's found something that could help. Only problem is getting in through the door and resealing it before the umbilical detaches from the ship. That or finding a way to reseal the outer hatch which got 'accidentally' blown off of its hinges. His ex-girlfriend was pretty much humping the leg of a complete stranger right in front of him. I'm surprised Mez bothered to aim at the door rather than Farvis's head. That wouldn't work as the helium would only act as an accelerant for the nucleosynthesis of heavier elements within the core of the star[sup][url=http://t2.lanl.gov/nis/tour/helium.html][LINK][/url][/sup], functionally increasing the star's lifespan. Although it would increase the central mass and therefore the chances of the star collapsing into a singularity rather than a dwarf star once the hydrogen fuel has been consumed, so it could still be used as a super weapon, as long as you didn't mind waiting a few million years for it to activate. "You may have won this time, but your great-great-great-great-great-great-great-great-great-great-great-great-great-grandchildren will pay!" If we were to get some hydrogen into its solid state and somehow put it on the star than the rest of the hydrogen would freeze before that piece become plasma, especially if you could place it on the relatively cool surface of the star. This would stop nuclear fusion in the star and you'd be left with solid hydrogen and helium gas, as well as trace element within the core. Your only problem would be finding a way to transport the solid hydrogen to the surface without it becoming plasma first. [/quote] It would if you ran it through tubes, similar to a geothermal system. That would require a material with a melting point above the temperature of the sun, but that's easy. You'd also have to shed heat faster than the sun does naturally in that spot to cool it. You could also place the solid hydrogen in a giant dewar, with a cooling system constantly cooling the stuff at the center.
