Neutrinos appear to break speed limit of Universe

The laws of Physics have been broken. At least, that is the apparent result of experiments at Cern, where subatomic particles seem to have travelled faster than the speed of light.

The speed of light (3oo million metres per second, or 671 million miles an hour) is the speed limit of the Universe. A fundamental law of nature is that nothing can possibly exceed such a velocity. And yet, in a 732-kilometre journey from Cern to the San Grasso Laboratory, tiny neutrinos have recently seemed to do just that – by turning up a fraction of a second too soon.

The researchers behind this seemingly surreal discovery have been quick to point out that these results will be treated cautiously, and more tests would need to be carried out to confirm its validity. Nevertheless, Einstein’s equations, modern Physics, and our understanding of reality could end up being turned completely on its head.

  1. When I first published this post, I had incorrectly stated that the speed of light is “300 metres per second”. Although this is remarkably fast, it is still many orders of magnitude too slow. The correct value is, of course, 300 MILLION metres per second. To get an idea of how fast that is, a beam of light could travel all the way around the world 7 times in one second.

    Anyway, I’ve edited it and rectified the statistics. Apologies for getting the science wrong. I really should proof-read my work more carefully!
