Faster Than the Speed of Light?

Econintersect:  It has been a universally accepted assumption that nothing can go faster than the speed of light, as anyone who has taken even one light-speedSMALLphysical science course can tell you.  After many decades many have accepted it as a fundamental law of physics.  It has been commonly called a "universal constant".  Last year a set of experiments at CERN (European Organization for Nuclear Research near Geneva, Switzerland) reported an apparently measurement of  the speed of some neutrinos slightly greater than the speed of light.  Some have suggested that this could have been measurement error (in fact Wikipedia says that is the case), but that has not stopped scientists from proceeding with a theoretical examination of the question.

Follow up:

While the question of whether or not particles actually have been observed moving faster than the speed of light, Jim Hill and Barry Cox, professors in the University of Adelaide School of Mathematical Sciences have extended the mathematics of Einstein to motion beyond the speed of light.  They say this has been done in a straighforward manner with no new physics principles or complex mathematics required.  They have not found how such motion might be achieved, simply that equations of motion exist that are well behaved in that regime.

Here is the full pres release from the University of Adelaide:

University of Adelaide applied mathematicians have extended Einstein's theory of special relativity to work beyond the speed of light.

Einstein's theory holds that nothing could move faster than the speed of light, but Professor Jim Hill and Dr Barry Cox in the University's School of Mathematical Sciences have developed new formulas that allow for travel beyond this limit.

Einstein's theory of special relativity was published in 1905 and explains how motion and speed is always relative to the observer's frame of reference. The theory connects measurements of the same physical incident viewed from these different points in a way that depends on the relative velocity of the two observers.

"Since the introduction of special relativity there has been much speculation as to whether or not it might be possible to travel faster than the speed of light, noting that there is no substantial evidence to suggest that this is presently feasible with any existing transportation mechanisms," said Professor Hill.

"About this time last year, experiments at CERN, the European centre for particle physics in Switzerland, suggested that perhaps neutrinos could be accelerated just a very small amount faster than the speed of light; at this point we started to think about how to deal with the issues from both a mathematical and physical perspective.

"Questions have since been raised over the experimental results but we were already well on our way to successfully formulating a theory of special relativity, applicable to relative velocities in excess of the speed of light.

"Our approach is a natural and logical extension of the Einstein Theory of Special Relativity, and produces anticipated formulae without the need for imaginary numbers or complicated physics."

The research has been published in the prestigious Proceedings of the Royal Society A in a paper, 'Einstein's special relativity beyond the speed of light'. Their formulas extend special relativity to a situation where the relative velocity can be infinite, and can be used to describe motion at speeds faster than light.

"We are mathematicians, not physicists, so we've approached this problem from a theoretical mathematical perspective," said Dr Cox. "Should it, however, be proven that motion faster than light is possible, then that would be game changing.

"Our paper doesn't try and explain how this could be achieved, just how equations of motion might operate in such regimes."
