– Speed of light discovery: would you go back in time? (Guardian, Sep. 23, 2011):
Physicists’ discovery of neutrinos that may travel faster than the speed of light raises the prospect of time-travelling particles. You’re not a tachyon, granted. But if you had the opportunity, would you go back in time?
– Speed of light broken – an expert’s view (Telegraph, Sep. 23, 2011):
If CERN scientists are correct in claiming they have observed particles travelling faster than the speed of light it would fundamentally change our understanding of the laws of physics, experts say.
Prof Jenny Thomas, of University College London, says the claims, if proven true, would call into question our very understanding of physics and the universe.
She said: “It would turn everything on its head. It is too awful to think about.
“The basic thing it that would be questioned is that there is an absolute speed limit which is the basis of special relativity and that is a huge building block of modern physics.
“It permeates everything to do with how we have modelled the universe and everything. It would be very hard to predict what the effects would be.”
Special relativity is integral to the understanding of particle accelerators and the creation of particle beams, which are of crucial importance in fields like medicine and engineering, she said.
It could even be that the most famous equation of all time, E=mc2, turns out to be incorrect because it is based on the law of special relativity, Prof Thomas said.
– Faster Than The Speed Of Light… OPERA Update (Universe Today, Sep. 24, 2011):
A few days ago, the physics world was turned upside down at the announcement of “faster than the speed of light”. The mighty neutrino has struck again by breaking the cosmic speed limit and traveling at a velocity 20 parts per million above light speed. To absolutely verify this occurrence, collaboration is needed from different sources and we’re here to give you the latest update.
“This result comes as a complete surprise,” said OPERA spokesperson, Antonio Ereditato of the University of Bern. “After many months of studies and cross checks we have not found any instrumental effect that could explain the result of the measurement. While OPERA researchers will continue their studies, we are also looking forward to independent measurements to fully assess the nature of this observation.”
