BeMoreCynical: It's a good question but I don't think anything on this page is claiming faster-than-light transportation. Just to clear up a
misperception, though: the inability to travel faster-than-light is only valid locally, not globally....for an example, let's say space is
2-dimensional, ok, and we've got a path like this:
A ========== B
(10 units long) and another path from A to B that looks like this:
A ========================================================== B
(a lot longer, say 100000 units long). If you need help imagining why there'd be two paths between A and B that are so different in length, take some
scissors and cut out a semi-circle from the piece of paper; ie, you draw a line
and then cut out the line and half of the circle around that line (it should look like a filled-in D has been cut out of the paper if you've done
this right). If A and B are the tips of the line, then one path from A to B is a long the diameter of the circle (ie, the line) and one path is along
the circumference. Clearly, the path along the circumference is longer.
Now, let's go back to our scenariou in which one path from A to B is 10 units long and one is 100000 units long; if everyone only knows about the
100000 unit path, they'd be like
"you can't travel from A to B in less than the time that it takes light to travel 100,000 units" (if 1 unit = 1 light year, then this'd be 100000
light years, for example)....
but if you went 1/10th the speed of light along the shorter path, you'd wind up finishing the short path in 100 years, say, which is still 1000 times
faster than anyone thinks you could have. Did you travel faster than light? You say no, because you only traveled 0.1 of the speed of light the whole
time; everyone else says yes, because as far as they know you went way, way faster than the speed of light.
So, it's not theoretically impossible to travel at rates seemingly faster than the speed of light if you just look at where you start and where you
stop; it is impossible to travel faster than the speed of light at any particular point in time, however....the ability to "go faster than light"
between A and B depends on whether there's a "shortcut" from A to B...some physicists and science fiction writers have speculated that black holes,
for example, would be able to distort the structure of space enough to make such a shortcut appear, and allow for (apparently) faster-than-light
travel...but it's still very much an open question as to whether any such shortcuts exist (none have been found so far) and even if they did exist
it's even more of an open question as to whether or not it'd be possible to travel through them (currently, it looks bad).
On this thread we're just speculating about whether the "propulsion mechanism" linked to in the first post is at all plausible; my take is that the
pieces described could be used to make a "lift-off-the-ground" stage of propulsion but that the link doesn't explain how the primary propulsion
system would work...others here have differing opinions, and probably know much more about this than i do.
