A story's effect does not prove its intent. Take Ed Wood's _Plan 9 from Outer Space_ for example. People laugh at his serious effort.

What actual evidence do you have that, "The message of Abraham and Isaac is about learning that sometimes what you feel is right emotionally is actually wrong, and sometimes what feels wrong emotionally is right"?

Light has momentum, not mass.

Beside that, special relativity has been corroborated again and again, tachyons are shown to be unstable due to their imaginary mass component, and physics as we know it simply doesn't hold up well in the presence of closed spacelike paths.

This isn't to say FTL travel is impossible. *Maybe* some way exists that gets around these huge obstacles, but when they say there's no known way it could work, it's not for lack of imagination.

Ah, okay. Right. So then I guess different waveforms represent different superpositions? What is the basis? The only one I can imagine is complex exponentials, but the closest thing those have to a "location" is phase, so I don't see how they could exhibit a propagation velocity. Maybe I'm just going to have to read a book about this.

You dialed 5483.
