I woke up at 3AM last night with my mind racing. The extremely important question that jolted me awake: How big is the Enterprise's viewscreen? So I did the math.
First off, it depends on which Enterprise you're talking about. The original Enterprise of the '60s, which I've been watching Season 1 of on Blu-ray (quite a good restoration, btw), had what seemed like a tiny ass screen when compared to the IMAX-like experience of the new movie Enterprise. But it's not actually that small.
