Cinematic or Scientific: Putting Time on Ice
Keywords:
Film, Physics, Relativity, Time Dilation, Ice Age, ScratAbstract
In Ice Age: Continental Drift, the character Scrat appears to trigger the breakup of Pangea within 64 s of screen time, compressing a geological process that occurred over approximately 225 million years. This study evaluates the time dilation required for such a compression by comparing Scrat’s elapsed time with that at Earth’s surface. The analysis demonstrates that both Earth’s gravity and the velocity of Scrat are fundamentally incapable of producing the cinematic effect depicted, highlighting the contrast between narrative storytelling and relativistic physics.
