I was watching an episode where Carter says the Prometheus can travel at just over half the speed of light at max sublight. It got me thinking what sort of energy requirements it would take to achieve that speed for something with so much mass.
I think so far we have only achieved getting objects to go .05% the speed of light. So lets just say the Prometheus weighs in at 100,000 tonnes. (would be more). What sort of energy would be required to accelerate that to 50% the speed of light. And how much would the mass be multiplied to? I have a feeling the answer would be a very unrealistic energy requirement, ala "3 shots vaporize!" and I dont care how good Naquadria is.  |

It's science fiction. They invent stuff... Like, ummm, we need to have some guy time travel using a phone booth we like to call the TARDIS which is implausible but raises that "What if...?" question pretty high. Whatever the energy requirements, you should rather see the bigger picture. They say Naquada can provide the energy for a 50% sublight? Then it is so... They invented this substance, they can name its properties the way they want to.  |

Sometimes they may use actual science/math that is real. Other times, they will invent whatever they want and say it will do whatever they want it to do. |

They also used the same substance in a bomb that was used on Jonas' world. While the energy output was supposed to be tremendous, it obviously didn't obliterate the entire planet. (much like a tainted ZPM would + most of the solar system).
I know its science fiction, but even the people behind the idea of '3 shots vaporize' regret it due to it being unrealistic (as well as a 'cheat') Just curious as to how much energy it really takes. And then to keep travelling at that speed over time. And all Jonas brought was a briefcase you could carry in one hand of the stuff, of which some was used on the interceptor that was destroyed along with the gate.

Thats because a ZPM can provide a lot more energy though. As we've seen, a ship takes around two weeks to reach Pegasus in hyperspace whereas a ship powered by a ZPM can reach Pegasus in a few days.
There's no way to find out because even the writers don't know. The chances are that even if they did want to put in an episode, they would just pick a large random number out of the air. You're better off not thinking of it and just accepting the number is big. |

i dont think the weight of an item matters in space as its a vacuum and there will be no resistance.

There are some forms of resistance in space, but there is not weight it doesn't matter, but mass does...  The greater your mass, the more thrust it takes to move it, and slow it down. |

No that's not it... Oh I know. Weigh is a measurement of force, and since force is a mass multiplied by an acceleration, and gravity is an acceleration and people have mass.... Oh okay. I remember now. |

Just always remember to initialize the inertial dampeners before jumping to Hyperspace, ok? Nobody likes to clean the goo from the back walls. |

The purpose of the inertial dampeners is to effectively reduce the mass of the ship. Therefore, you're not accelerating as much mass and require less power.
