I don't think this is actually what is believed to happen. For example,
if you travel close to the speed of light but go in a big circle back to
your clock then you would actually find that your watch was behind the
clock, ie time DID actually travel slower for you than for the clock,
not merely look like it. How this relates to traveling faster than light
I have no idea. Physics was never my strongest points.

On the point of complex number (I think they were mentioned in this
thread!!!), a very simple example is...

Suppose during a calculation you are performing you need to find the
square root of (-4), what do you do??? At some point later in your
calculation you the multiply the result by itself then you should get
back to (-4). Imaginary numbers allow you to do this.
