That AI-Generated Boulder Would Need ~20 Million Newtons to Move

A playful physics estimate of a boulder being moved in a (likely AI-generated) video: at 8-10m across and typical Himalayan rock density (2600 kg/m³), it weighs roughly 1,500-3,000 metric tons.

The drag force needed to move it is estimated at 5-20 million newtons — for comparison, a Falcon Heavy first stage produces about 23 million newtons. Commenters use the back-of-envelope math to poke fun at generated-video physics.
