If you ask me, that's just like saying man can't fly because someone invented some giant replica bird wings and tried flapping in the sky and yet just fell out of the sky and accomplished only getting a headache, with the man saying "It can't be done." And yet, the Wright Brothers proved us wrong over a century ago. If you ask me, FTL drive may be a different can of worms than just getting off the ground and into the sky, but what makes you think we still can't do it, ever? Sure, we probably might not do it in our lifetimes, but please, justify the pessimism in your statements; I may not be an expert in science babble, but I'm still as yet not convinced.
(Again with the absolutes, Mr. Johnson... *sigh* *hits head* Doh!)
At the speed of light, mass is infinite and time comes to a stand still.... This means that when you try to traverse the light barrier, not only will every computer on board the ship including the human brains of the pilots cease to function, but the area of spacetime the ship and it's surroundings are in will collapse into a black hole...
Or, to use stormbringers method, you have to twist spacetime into some kind of Spacetime Mandelbrot set that encompasses you and your spacecraft and move space and time itself across the void, oh yeah, and again you have to be bloody careful that the spacetime around you doesn't implode into a black hole or or that the space time metric doesn't undergo some bizarre shift in 4 dimensional tidal forces that rip you apart...
I love watching episodes of Start Trek, particularly any involving T'pol or 7 of 9, as much as the next person, but you must admit, this is a pretty stern obstacle course...
And please, I am not pessimisstic... Frankly, even if we could, I really don't see how travelling faster in light is going to make mankind happier or healthier in any way... Hell, I'm happy as a pig in sh*t and I haven't left my own town in the last eight weeks...
And another thing, don't you think it's a bit pathetic to remove (not that I care) two Karma points in eighteen hours from someone who's only offense towards you is not believing in the possibility of FTL space travel?
