I just love the expression "near-faster-than-light travel."

It's an utterly meaningless term, since the concept of speed ceases to mean anything in the physical sense were one to surpass the speed of light, and also because the closest thing that is "nearly" faster than light is light itself.

Of course, nothing can move at the speed of light, so what the expression really means is "travel at close to the speed of light," which is technologically possible now, requiring only a means of continuous acceleration (e.g. an engine that burns fuel on a perpetual basis).
