But it’s not only in a Galway coroner’s court that the laws of nature have been suspended. They’re just as dysfunctional at the world’s most advanced scientific establishment – CERN.
Europe’s premier physics lab has measured particles travelling . Fancy that. This is a little troubling to them though, because for a physicist, matter moving faster than light makes about as much sense as God knocking on the door, presenting you with an iguana wrapped in newspaper, saying “Call me Susan, I have no legs for hosepipe” and turning into a forest of lemon trees. It doesn’t happen, it can’t happen, it won’t happen.
So as they make their lemonade, the boys and girls at CERN have to try to figure out where things went awry. Those particles can’t really have gone faster than light, can they? They have mass – which is a technical way of saying they weigh something – and a thing with mass can’t travel even as fast as light, never mind faster. This is because…
Well, this is because the world is a lot freakin’ weirder than it looks. You may not have noticed this – actually you couldn’t possibly – but the faster you move, the heavier you get. It isn’t detectable at the speeds even spacecraft travel at, but the effect gets more pronounced as you approach the speed of light. So pronounced in fact that if you ever travelled at the speed of light, you’d weigh an infinite amount. Which can’t be pleasant.
To make it worse, as you go faster you shrink in the direction of travel. (So much for the symbolism of the sports car then.) At the speed of light, your length front-to-back would be zero. Something with no length at all but which weighs more than the whole universe isn’t really a possible thing, so matter never can go as fast as light. The only reason light itself can manage is that it has no mass and no length to change.
Another way to think of it: The speed of light is the infinity of speed. Saying “faster than light” is like saying “more than infinity”, it’s a meaningless statement. So if this experiment showed particles of matter going from A to B in less time than light could, you’re forced to conclude that, well, perhaps A isn’t as far from B as you thought. Or maybe the particles found some sort of short cut. Or… the universe just shrunk or… something.
Those are actually genuine suggestions. Most modern theories of the universe tend to have a few extra spatial dimensions lying around; not just the Up-Down, Forward-Back and Left-Right we know, but also Hoo-Hah, Abba-Dabba and Hosni-Mubarak. Say. Maybe those extra dimensions form hidden spaces that the particles (called neutrinos) can cut through.
Or maybe not. Frankly no one knows. Any theory that accounts for a deviation from such a fundamental law has to be so darn theoretical that it may as well just be a particularly pretty form of hand-waving. Most likely explanation? They’ve simply made a mistake. They are some of the most intelligent people on the planet, they have the best lab in the world, and they’ve spent the last six months re-checking their results, but still the best explanation is that they put a decimal point in the wrong place somewhere. Almost anything is more likely than that their results are actually right.
I have a theory of my own. Of course.
CERN is headquartered in Geneva, Switzerland. That’s good, we expect things to be done with precision there. But in order to measure such high speeds, the neutrinos have to be sent to a target that’s some distance away. Quite a distance actually. Further than Switzerland is big. In Italy in fact.
Italy. Of course they’re getting figures that don’t reflect reality. Berlusconi is probably pocketing some of those neutrinos himself.
