On the Matter of Matter.

I noticed quite a lot of people on here use Alcubierre style drives for their travel.

This is quite an interesting paper on the technology.

To sum up a few points:
-Particles caught in the bubble experience massive red-shifting
-The negative energy produced, may, infact, time travel.
-There is no upper limit on the amount of particles the bubble can pickup along the way
-The negative energy used is also theorised to do horrible things to the universe and cause vacuum metastability events.
-They might actually make better weapons than transport systems.

Truly this is a scientific post.
