Just as a quick header note to this video: It’s probably better if you watch the movie before you watch my commentary of it.
The bottom line is that Hollywood’s botched attempts at employing real science in their features is an insult to the intelligence of the movie going public. At least that’s my opinion… because the alternative would basically be for everyone to say: “Yes, we are that dumb! None of what was portrayed on the silver screen went against our understanding of high school grade science!” And I just don’t see that happening.
