Will mankind ever achieve the ability to travel faster than the speed of light? If you think so, do you think soon (say, within 100 years) or far off in the future?
Time travel and faster than light travel are joined at the physics hip. Current theory hypothesizes that worm holes can be used to do both. Implementation is an exercise left up to the student
But a lot of very hairy and bleeding-edge math and physics are being argued by guys like Stephen Hawking as to whether or not this is even within light years of being theoretically possible.
I like to keep up on this stuff (and things like string theory) just to satisfy a base curiousness but I barely understand it on a very cursory level and have a very amateur knowledge of it.
Whether or not it's even possible will maybe be deduced in 25-50 years. I'd give it actually happening a 50-50 shot in the next 100 years. The problem is, the more we find out, the more we understand we really don't know anything.
