If something travels faster than light, its speed has no meaning, in that by contriving the right itinerary, it can travel in such a way that its present becomes the past of some part of the measuring frame's space; it can then travel FTL to that part of its space, arriving in the measuring frame's past, then returning to its original destination from there, and so arrive at its destination before it started.
This is because a plane representing the present in a space-time diagram (all those points in spacetime drawn outward from a point, at right angles to the line of a point's travel forward in time) will tilt according to its velocity, so points travelling at different velocities, being in different inertial frames, have different planes of the present.

And if Superman flies counter to the Earth's rotation, he can go back in time too, by crossing time zones in reverse.

What happened to then?
We're past then.
When?
Just now.
When will then be now?

That was the cool part of that show: watching the ship evolve as they went. Constant upgrades to engines, defenses and weapons.

Yeah, but you just saw how they looked like in their glass coffins, doped to the brim. Plus, you create a total dependency on a single point of failure - the spice MUST flow, or else. At least till the Tleilaxu come up with synthetic melange. Then the surface of Rakis can be turned to glass and nobody but the Rakians is worse off from it.

Yeah, that was really where Herbert lost the magic of the series. It started about spice as oil, but if you come up with synthetic oil and no one cares about the Middle East anymore, then why would anyone want to read about some sheikh?

If something travels faster than light, its speed has no meaning, in that by contriving the right itinerary, it can travel in such a way that its present becomes the past of some part of the measuring frame's space; it can then travel FTL to that part of its space, arriving in the measuring frame's past, then returning to its original destination from there, and so arrive at its destination before it started.
This is because a plane representing the present in a space-time diagram (all those points in spacetime drawn outward from a point, at right angles to the line of a point's travel forward in time) will tilt according to its velocity, so points travelling at different velocities, being in different inertial frames, have different planes of the present.
To travel faster than light does not mean that you are entering any sort of time travel in any way shape or form.(that was someone's theory) The object won't change form in space in vacuum because there is no drag so passing the speed of light an object is still in the same form as it was by design and exceeding the speed of light beyond the distance of the universes diameter in one second still will not achieve time travel. The experience one would expect would not be noticeable if you were going from Earth to another system a 1000 light years away, it would still take a 1000 years to get there. So for space travel the fastest method is by Worm holes and that will get you from the solar system to another galaxy(any one or another dimension) in one second. If a worm hole were used for communications then there would be no lag when communicating with some one in another system or galaxy.
