'Pacific Rim' Vs. Real World Physics: Giant Robots, Galileo, And The Square Cube Law

Pacific Rim looks awesome and all, but let's talk about science for a second. Specifically, let's talk about the science, or lack thereof, behind completely awesome giant robots.

Guillermo Del Toro's upcoming sci-fi action pic is probably going to be as awesome as the trailers make it look, unless you're the kind of person who hates the sight of huge mecha fighting against equally huge monsters, in which case please show yourself out. How could you not love enormous robots punching out enormous monsters who lay waste to entire cities? Giant robots represents 90 percent of what we want the future to be like (the other 10 percent: flying cars, and a male birth control pill.) They're extremely cool looking, they transform, and for sheer shock factor they're impossible to beat.

We want them so badly, but could we have them in real life? Unfortunately, hell no. Not because of budgetary constraints, frustratingly missing confirmation of alien life, or the lack of a decent fuel source. There's a bigger problem facing these robots than any alien invasion: Physics.
