Was Einstein wrong, can neutrinos blow through the speed of light stop sign?
An experiment purporting to show that subatomic particles can travel faster than light has scientists’ heads spinning. If confirmed, it would undermine key pillars of modern physics.
At a presentation in Switzerland, scientists said Friday they had recorded ghostlike particles, known as neutrinos, a tiny bit faster than light—an apparent breach of the cosmic speed limit set down by Albert Einstein more than a century ago.
. . .
Neutrinos are particles with almost no mass and no charge, and they can pass through ordinary matter unaffected. At any given moment, billions harmlessly stream through a person’s body.
In the experiment known as the Oscillation Project with Emulsion-Tracking Apparatus, neutrinos were measured as traveling slightly faster than light on a 450-mile trip from CERN near Geneva to the Gran Sasso underground lab in central Italy. The particles moved at a velocity just above the speed of light. That result was based on more than 15,000 neutrino events measured at the Italian lab, CERN said.

Are these results science fact or science fiction? Beats me. If it is true, it’s going to turn physics as we know it on its head.
/stay tuned, this is sure to be a hot topic of scientific debate for quite some time
