Except even if possible (it has not been proven) the energy required is likely more than the universe contains. Worse, those in a Alcubierre drive space ship travel in "real time" and thus to go to another galaxy would only require a couple of hundred thousand or so generations.
Big oops.
Oh BS.
We did that with Helios 2, and used the Sun's gravitational energy.
We made it up to 43.63 mi/s, which is the fastest man-made object ever, but still it's only 1/4,000th the speed of light.
BFD
The alcubierre drive would require an enormous amount of energy if it was used to travel at superluminal speeds. There is a unique difference.
You could still travel a fraction off the speed of light and never need to invoke superfluous amounts of energy. I don't understand this:
''Worse, those in a Alcubierre drive space ship travel in "real time" and thus to go to another galaxy would only require a couple of hundred thousand or so generations. ''
Also, you are rationalizing our capabilities to 1/4000th of the speed of light using the Sling Shot effect. The Sling Shot effect depends on the speed of the planet and the rotation. Find a large enough planet, or any cosmic object to drag you round, with it moving at a reasonably fast speed then you will break those lower speeds easily.
ps... this wouldn't even need to be hard. Find a planet moving at half the speed of light and sling shot it. You will get back a speed nearly the velocity of light.
