I am not even close to qualified enough to critique this paper, but I did find it interesting. The authors speculate about how you could create a warp drive -- an engine for faster than light travel -- by creating a bubble of expansion and contraction in spacetime. They speculate that an advanced enough civilization could in theory do so.
However, I was particularly struck by this sentence:
Assuming some arbitrarily advanced civilization were able to create such an effect we might postulate that this civilization were able to utilize the most efficient method of energy production - matter antimatter annihilation. Using E = mc^2 this warp bubble would require around 10^28Kg of antimatter to generate, roughly the mass-energy of the planet Jupiter.
Bummer.
You know it is tough traveling between the stars when every time you want to do it you have to come up with a lump of antimatter the size of a planet. That alone might put the kiebash on this whole business.

All you need are Dilithium crystals.
It's amazing how on target Gene Rodenberry and his staff of writers were regarding technology.
Two planets: you need the anti-Jupiter plus a regular Jupiter.
It may not be eco-friendly, but look at the maximum speed: 10^32 times the speed of light! Cross the entirety of the known universe in 10^-15 seconds!
What's the secret of a successful trip? Planet!
Well, obviously. We learn from Futurama that one pound of anti-matter weighs 10,000 pounds, so this is no surprise.
