Tonight I am presenting the latest episode from the PBS Idea Channel YouTube channel. Neil DeGrasse Tyson has made a small game out of decrying the factual inaccuracies of popular movies, but do these noted inaccuracies actually…matter? On one hand, showing the dinosaurs in Jurassic World without feathers is a scientific error, but what about the fact that Jurassic World exists at all? Isn’t it just fantasy? Does it matter that in Gravity, gravity itself seemed to not necessarily obey our current understanding of it? Join Mike on this week’s episode of Idea Channel as he looks at what works of fiction may or may not owe to actual reality.
