[QUOTE="Galethorn, post: 2266326, member: 7888"] I'm definately a fan of the onboard jump drive concept...the following features are things I'd consider icing on the 'interstellar travel cake' * Only big ships (battleships, carriers, civilian freighters and transports, and some smaller specialized ships) can carry one * It takes a while to recharge the capacitors (or whatever) between jumps * The further something is away, the more difficult it is to plot (so, the farther away you are, the farther from gravity wells you should plot your destination) * The bigger the ship, the more difficult the calculations (so it takes a long time/a huge navigation crew/computer to plot a jump for a big ship) If you write the 'science' of it off as 'quantum teleportation', then it's even semi-believable (and to justify only larger ships being able to jump...well, only big ships can have fusion/matter-antimatter/zero-point/whatever reactors, of course). [b]And now for a short dissertation on travelling at (or faster than) light.[/b] Now, travelling faster than light in realspace (or whatever you want to call 'normal space')...that's just impossible. Even if you had truly infinite power to keep speeding up, and could negate the effects of the g-force of acceleration, and didn't mind the relativistic effects on time...you'd run into one fundimental problem as you approached the speed of light... Mass (which, at its heart, isn't "how much" of something you have, but actually the resistance to change in velocity of an object) increases exponentially (or some other mathmatical word ending in 'ially' that means "increasing returns") as you approach the speed of light, and the reason it would take infinite power to accelerate to the speed of light is because the mass of the object would increase infinitely. And, we run into a couple of problems on the way to infinite mass. 1. Any object that isn't currently fusing (i.e. an active sun) over 1.4 times the mass of our sun collapses in on itself, causing its electrons and protons to 'blow each other up,' resulting in just neutrons crammed together in such a way that they're incredibly dense. So, say you could deal with being a neutron for a little while (!), and kept speeding up...well... 2. Any object that isn't currently fusing (i.e. an active sun) over 3 times the mass of our sun collapses in on itself, and turns into a black hole. Yeah, a black hole. So, the moral of this story is that if you got your FTL drive fired up, you'd turn into a black hole travelling at close to the speed of light. A great idea for a weapon, but not a very fun way to travel. Ok, I'm done. [/QUOTE]
