Battle briefing Where we are now
Battle of Maxia · U.S.S. Stargazer
A damaged ship. An attacker closing in.
Captain Jean-Luc Picard has a desperate move in mind: a brief burst of warp speed toward the enemy, stopping close to its bow. He is counting on the attacker’s picture of the battle falling behind his ship’s actual position.
You’ll watch the maneuver from outside, then through the opponent’s eyes. Your question: where is the Stargazer, and what is the enemy receiving?

Commander: how many ships are you seeing?
A damaged Stargazer changes course. Follow the information before choosing a target.
Your first impression:
There is no penalty for wondering.
A thought experiment: hypothetical faster-than-light travel, ordinary light propagation, approximately flat spacetime, and a stationary observer.
Follow the evidence
One arrival time. Different histories.
Same viewing direction: these histories overlap. Three mathematical solutions do not guarantee three separately visible ships.
Separate histories for teaching
This arrangement separates the histories for explanation. It is not the opponent’s view.
Change one condition
Will the deception still work?
Fictional tactical deduction: this opponent knows the exact course and timing. Optical histories still arrive; prediction changes its position estimate.
Compare constant straight-line motion
A ship that moves at a constant superluminal velocity can have up to two arrival solutions. Starting and stopping change the geometry. Acceleration alone does not guarantee three.
Separate comparison: x = vt, sideways offset 1 light-second, observer time 9 seconds. The main scene retains your finite maneuver.
Science behind the scene
The equation
tobserved = temitted + distance / c
For a single observation time, find every emission event whose light arrives then. The point emitter never duplicates. Its transit history can arrive in reverse order.
For ordinary subluminal motion, the arrival-time function increases: later light arrives later. There is at most one solution.
The chosen model
Our teaching values begin 12 light-seconds away, peak at 4c, and make the maneuver in 3 seconds. A cubic transition begins and ends at rest. Duration and peak speed determine the stopping distance.
Velocity is continuous; acceleration changes abruptly at the endpoints. The sideways offset is 1 light-second except in Direct approach. The spacetime view draws the curved light-cone section for that offset.
Hull sizes, surface lighting, and apparent brightness are illustrative. This point-emitter model does not calculate finite-hull light travel, occlusion, aberration, or a telescope image.
Further reading
The retarded-time analysis explains how multiple emission events can reach one observer together. Our chosen speeds, distances, and clearance boundary are teaching assumptions; this model does not demonstrate a working warp drive.
An imagined briefing for this exploration, inspired by Star Trek. These recommendations are our tactical deductions, not quoted Starfleet doctrine.
Know the age of your information
Commander, a sensor report describes what reached you. Before acting on a contact, ask when that information left its source. Multiple images may be different histories of one vessel.
Plan the arrival, not just the jump
Account for stopping distance, a clear arrival point, and the condition of your propulsion system. A maneuver that confuses the opponent can still leave your crew exposed.
Assume the opponent can learn
A familiar trick invites a countermeasure. Compare fresh reports with the course you expect the vessel to take. In our ideal-predictor exercise, exact knowledge removes the position error while delayed optical histories still arrive.
The command decision
Timing errors, uncertain enemy position, collision risk, an exposed arrival point, and damaged propulsion may undo the opportunity. An opponent that anticipates the maneuver may predict the current position.
These are tactical deductions and fictional engineering assumptions. Multiple images alone do not establish a hit probability or a battle outcome.
