Gambit (2) - S7-E5
Other mistake: When the raiders' vessel fires on the Enterprise, only the starboard nacelle is hit. Right after the impact, Worf reports the port nacelle hit, then the starboard.
Other mistake: When the ship is at max warp and Geordi states that at maximum warp the ship can only sustain two hours of emergency life support, Data, Troi and Worf are on the holodeck attempting to stop the train, but back in the bridge before they do you can see the view screen in the background and the bridge glass dome above Geordi, Picard and Riker that the ship is not moving at warp speed and is at standstill.
All Good Things... (1) - S7-E25
Other mistake: When Picard first meets Data in the past, Data's rank insignia is wrong. He's always held the rank of Lieutenant Commander, signified by two gold pips, and one with black in the center. However, Data has one gold, one with black, signifying Lieutenant.
Answer: Prior to the supernova, English script "three point eight billion kilometers", German script "3.8 Milliarden km" speed of light in vacuum c = 299,792,458 m/s 3.8 billion km = 3,800,000,000 km = 3,800,000,000,000 m (3,800 = 3.8 thousand, 3,800,000 = 3.8 million, 3,800,000,000 = 3.8 billion) in physics formula c represents speed aka. Velocity = v, s means distance (abbreviation not known to me), t = time v = s/t v * t = s t = s/v v = 299,792,458 m/s s = 3,800,000,000,000 m 3,800,000,000,000 m / 299,792,458 m/s = 12,675.435617529778 s = 3.5 hours The impression in the scene could be convincing of 1-5 minutes prior to seeing the supernova, and not 3.5 hours. I would argue in order to give them the benefit of the doubt they would have to be either less specific about the distance travelled or more respectful of c. The movement of the spaceship aka. Matter in this case being faster than c is implied to be part of the fictional part of sci-fi and not a logical oversight on my end. c is constant.
Sorry, this was meant as "mistake" under episode "Tin Man." Not familiar with the buttons here.
