Travelling At The Speed Of Light Could Make Your Bum Look Great

Travelling At The Speed Of Light Could Make Your Bum Look Great

Next time you’re trying to squeeze into your skinny jeans, it might pay to give physics a thought. Depending on how fast you’re travelling, your fat frame could look a little different.

Randall Munroe explains in the mouse-over text of today’s XKCD:

“It’s commonly believed that Lorentz contraction makes objects appear flatter along the direction of travel. However, this ignores light travel times. In fact, a fast-moving butt would appear rotated toward the observer but not substantially distorted.”

Still, every little bit helps, right? Now you just need to find a spaceship that can go fast enough to make you look good. [XKCD]
