Continuity mistake: When Geordi falls down the hole in the beginning of the episode his visor is seen to his right. When he wakes up he finds it to his left.
Continuity mistake: After Wesley makes his neutrino pulse suggestion, Picard tells him to go do it. Wesley walks off camera. Then there's a commercial break, and Wesley is back on the bridge in the long shots. A few minutes later we hear the turbo-lift and Wesley walks back onto the bridge.





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.
