Corrected entry: The science behind what happens to Paris in this episode is fundamentally flawed. The Doctor states that Tom is "evolving," however the smallest unit of evolution is a population. An individual cannot evolve, only mutate. Also, evolution is not a predestined process as it is apparently portrayed in this episode. It is a random occurrence, and so there is no way to know what humanity will evolve into.
Corrected entry: In this episode it is stated that Warp 10 is actually infinite Warp - a craft travelling at such a velocity will simultaneously occupy every point in the universe. However in the Star Trek: The Next Generation episode All Good Things part 2 (shot several years earlier), the Captain Riker of the future at one point orders the modified Enterprise to be taken to Warp 13. Even if the problems of using Warp 10 were ever ironed out, how would it be possible to go faster?
