Sometimes truth is stranger than fiction.
The Shalimar Treaty is a strange treaty about the light-speed barrier, and it's implications on causality. On the surface it is a fictitious peace treaty between Klingon and Federation forces, that backfires. Secondarily, it is between the camps of Einsteinian Special Relativity, and the observers of superluminal events.

Mostly, it is about cause and effect, and has as it's theme something from the future-fiction Star Trek drawn into the present-reality to describe a causality paradox.

However the arguments used to describe the paradox seem to apply equally well to the sound barrier. Let's say our FTL ship starts at position #1, and broadcasts "A". It travels towards the observer to position #2, where it broadcasts "B", and continues to position #3 where it broadcasts "C". To the observer, the ship arrives first, then it sees "C" then "B" then "A". Apparently backwards in time, and one might even say that it could prophesize the occurance of "A", given that it saw "C" and then "B".
But if we switch the scenario to sound waves, say the craft is using morse code, and traveling at mach 1.1, then what is the difference?
What do you think of this?
