The science and even the popular press are filled with excitement at the moment after the OPERA experiment at Europe’s giant particle physics laboratory, CERN (to which I applied for a summer job when I was 16, but that’s another story). Apparently, neutrinos sent from CERN and captured at Italy’s INFN Gran Sasso Laboratory about 730 km away are arriving faster than scientists thought physically possible – faster than the speed of light travelling in a vacuum.

I had to write about this because the news reporting has really annoyed me. Every announcement has said that Einstein might be wrong because he (special relativity) says nothing can travel faster than light in a vacuum. Poppycock! (As I’m being polite.) What the theory says is that nothing that has what scientists call “rest mass” can travel at the speed of light – there isn’t any block on things travelling faster. It’s always slightly surprised me that in a discipline where mathematical physicists are used to things called discontinuous functions, I rarely hear of people willing to accept that something could go from “slower” to “faster” without having to “equal”, but it might be possible.

One argument against travelling faster than light is that, although there are solutions to Einstein’s equations, they contain the square root of minus one which we sometimes call an “imaginary” number (as opposed to other numbers that are called “real”). This is a brilliant example of mathematical spin and how it has actually damaged our understanding of mathematics and the universe. There is nothing less real about these imaginary numbers than what are called the real ones. It’s actually by combining both set that we achieve a far deeper understanding of the mathematical and physical universe. But way back when they were first introduced, French mathematician and philosopher Rene Decartes was very distrustful of them so coined the term imaginary as a pejorative description, hoping it would mean they didn’t catch on. He’s got a lot to answer for.

What is a neutrino? Like the similarly named neutron, a neutrino carries no net electric charge (compared with other familiar subatomic particles such as electrons (-1) or protons (+1). Unlike the neutron, the neutrino has almost (but not quite) no mass. Having no charge and almost no mass makes a neutrino extremely difficult to detect.

Back to relativity! Anything travelling faster than light in relativity yields solutions including the square root of minus one which people have interpreted as meaning travelling backwards in time. That’s the reason for the joke that’s currently doing the rounds on the twittersphere:

Barman: “I’m sorry, sir. We don’t serve neutrinos in here.”

A neutrino walks into a bar.

With every revelation of the Hubble telescope, the universe appears ever more mind boggling. According to NASA, a massive black hole has been detected by the Hubble in the M84 galaxy:

"The Space Telescope Imaging Spectrograph measured a velocity of 880,000 mph within 26 light-years of the galaxy's center. This measurement allowed astronomers to calculate that the black hole contains at least 300 million solar masses. M84 is located in the Virgo Cluster of galaxies, 50 million light-years from Earth, and a nearby neighbor to the more massive M87 galaxy, which also contains an extremely massive black hole." (NASA)

Just think of it. We are but a speck in a quite small solar system "only" several hundred million miles across. Our solar system is among millions of other solar systems inside the Milky Way galaxy, which itself is only one among millions of other galaxies, of which M84 and M87 are just two. Those two galaxies are part of a cluster of galaxies called the Virgo Cluster, which itself is 50 million light years away from us.

That means it would take us 50 million years traveling at the speed of light (about186,000 miles per second) to get there. I would try to calculate the distance in miles. But I'm certain I'd drop too many zeroes. Perhaps even more amazingly, on top of it all, the black hole discovered inside galaxy M84 contains the masses of more than 300 million suns. And, get this, according to the NASA report, in the middle of that galaxy velocities of 880,000 miles per hour have been measured. Such high velocities are apparently used by scientists to detect the presence of a black hole.

Compared to the speed of light, 880,000 miles per hour is really way slow. But just think. Traveling at that speed, it would only take us around 15 minutes to get to our moon. This is definitely one of those "things that make you go "Hmmmm". The scope is almost beyond comprehension. If you ask me, in the overall scheme of things, whether or not the furniture got dusted this week is probably not worth worrying about.
