The idea that, if the laws of physics don't mention it, it isn't real is also totally unjustified.

But does that mean that zebras aren't real? Any physicist who insists on this can't see the wood for the carbon.Short piece on time in the January edition of The Times's Eureka Science magazine, Only available online through the Murdoch pay wall.
