This renders a large number of observations in our subluminal universe illusionary. Prior to the invention of the Markov Drive (or failing that, detection of FTL gravitational signals), none of this mattered. Relativity was maintained throughout because FTL travel and communications weren’t possible. Nor could we accelerate a spaceship to high enough relativistic speeds to really begin to investigate the issue. Only now, with access to both the sub- and superluminal realms, has the truth become clear.

As the light signatures of our modern-day FTL trips begin to reach the nearby stars, an observer positioned there with a powerful enough telescope would see a confusing series of images as ships and signals pop out of nowhere, seemingly out of order. However, by observing TEQs instead of photons, the true order of events may be established (or by physically traveling to the sources of the images).

The exact mechanism that prevents causality violations in STL space is the top velocity of the TEQs. As long as that isn’t broken (and no known mechanism would allow for this), FTL will never allow for time travel into the past. And for that we should be grateful. A non-causal universe would be sheer chaos.

With our overview finished, we will now examine the theoretical possibility of using conditioned EM fields to reduce inertial effects and to lessen or increase perceived gravity. Although as yet impractical with our current levels of antimatter production, in the future, this could be a means of—

SHIP-BASED COMBAT IN SPACE

Transcribed from Professor Chung’s Lecture at the UMC Naval Academy, Earth (2242)

Good afternoon, cadets. Be seated.

Over the next six weeks, you’ll receive the finest education the UMC can muster on the means and methods of ship-based combat. Fighting in space isn’t twice as hard as fighting in air or water. It isn’t three or four times as hard. It’s an entire order of magnitude more difficult.

Zero-g is a non-intuitive environment for the human brain. Even if you grew up on a ship or station, as some of you have, there are aspects of inertial maneuvering you will not understand without proper instruction. And no matter how sharp you might be when it comes to good old slower than light, FTL throws those rules out the airlock and stomps on them until they’re a bloody mess.

The maneuvering capabilities of your vessel and those you fight alongside will determine where you can fight, who you can fight, and—if needed—the requirements of retreat. Space, as has often been stated, is not only large, it’s larger than you can imagine. If you can’t close the distance between you and your target, they are invulnerable to your fire. This is why it is often advantageous to drop out of FTL with a high degree of relative motion. But not always. Circumstances vary, and as officers, you will be called upon to make those sorts of judgment calls.
