You mentioned no need of the deflectors if the Enterprise is NOT moving. Sir I correct you, the deflectors primary use is during impulse speed. You were of course overlooking that ability or you would have mentioned it. I also include the “Speed Chart” explaining impulse and warp speeds.
Some here, like you, have quoted individual episodes to prove a point. However I remind you there are some episodes that abuse physics and Star Trek physics to move the plot. As is explained by the physics that work on each script, since the days of Gene scientist and physicist have been employed to ensure the accuracy of the science in Star Trek. Nevertheless a few episodes break the laws of physics to employ a plot point. The best and most well-known break is the episode “The Relic” Scotty is using his derelict ship to hold the door open on a Dyson Sphere, in order to do so he must keep the shields at maximum. When the Enterprise-D slips through the door they transport Scotty aboard THROUGH the shields. That feat is impossible. Nevertheless the writers were stuck on how to save him so they broke a rule. It has never been done again and will not be. It was also never satisfactorily explained. Writers sometimes override the script supervisor to move the story. When that happens the “skip” in physics is not accepted in future episodes. In Star Trek 09 (2009 the first JJ Abrams Star Trek) Scotty and old Spock have a detailed conversation explaining the warp effect. In that conversation Scotty acknowledges that the ship NEVER moves. So you see Larry just because someone’s sounds right and wordy does not make it so. If you are going to debate the physics of Star Trek study the physics of Star Trek for yourself and not take someone’s word. If the ship moved then we would be watching Star Wars, fiction.
