Faster Than Light Particles! So, Warp Speed Ahead, Right???

September 22, 2011 Leave a comment Go to comments

The OPERA detector at Gran Sasso National Laboratory in Italy

I’ll have more to say about this story once I see the work on arXiv, but I feel I should comment now because this story is exploding.

The interwebs and blogospheres are abuzz with the news that researchers at CERN have measured the velocity of neutrinos which seem to be travelling faster than light.

Neutrinos are nearly massless  subatomic particles which have been known to travel near the speed of light. But, like all other things in the universe, they are not supposed to be able to travel faster than light.

Basically the experiment involves the creation of neutrinos at CERN in Geneva, Switzerland, and the neutrinos travelling 730 km to a laboratory 1,400 meters underground in Italy. There, an experiment called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) detects those neutrinos and measures how quickly it took them to make the trip.

The neutrinos arrived 60 nanoseconds sooner than they should have. This means they were travelling at a speed of about 299 800 km/s, which is slightly higher than the speed of light, which is about 299 792 km/s.

This discovery will rock the very foundation upon which modern physics is built. Seriously, this is like the discovery that the world is round or wave-particle duality; it’s a complete game-changer.

If it’s true.

Like a lot of folks out there, I am quite skeptical of this discovery. Think of it this way: which of these two scenarios is more likely,

  1. Particles can travel faster than light, completely re-writing modern physics and decades of previous research. Or,
  2. These guys made an innocent mistake.

Now, it is certainly possible that this discovery will turn out to be genuine. However, it is much more likely that there was some kind of error or misinterpretation which has led to this result.

I would like to point out that the researchers have revealed their work in the proper way. They are excited, but very skeptical themselves and are asking the academic community to review their work and try to find a flaw. Antonio Ereditato, a physicist at the University of Bern in Switzerland and OPERA’s spokesman said in an interview

Whenever you are in these conditions, then you have to go to the community

THIS is science in action, folks! A group of physicists think they have discovered something awesome. But they haven’t started trumpeting their results like they have been absolutely confirmed, no emails were leaked suggesting the discovery, and they didn’t go to some rogue publication to get their work in print prior to peer-review.

Beautiful, isn’t it?

I am very hopeful this turns out to be a genuine discovery. I can’t wait to read the papers and hear the response from the scientific community.
