That post about Science on the Simpsons made me think about science in music. More specifically, science that’s wrong in song. This is actual problematic physics, not some mention of fantasy or fiction, in which the rules of science might not apply. Here are a few I can think of off the top of my iPod:

Creedence Clearwater Revival, Up Around the Bend

You can ponder perpetual motion

OK, so pondering perpetual motion may not be impossible, but is ultimately fruitless

Jefferson Starship, Girl With the Hungry Eyes

I like to move at the speed of light
Albert says I can’t, but I can

B-52s, Planet Claire

She drove a Plymouth Satellite
Faster than the speed of light

Barenaked Ladies, It’s All Been Done

The whole song is about immortality

A Google search shows there are a lot of lyrics using speed of light as a literary device, like “living at the speed of light,” but I don’t think those count. But I did find this one:

Coldplay, Speed of Sound

Look up, I look up at night,
Planets are moving at the speed of light.
