<i>Travelling faster than light!</i>

Applied mathematicians have extended Einstein's theory of special relativity to work beyond the speed of light.
Einstein's famous theory holds that nothing could move faster than light, but academics at the University of Adelaide, Australia, have developed new formulas to describe travel beyond this limit.
The theory of special relativity was published in 1905 and explains how motion and speed is always relative to the observer's frame of reference.
As well as this, relativity introduced the concept of time dilation, which suggests that the faster you travel the more time seems to slow.
According to the mass-energy equivalence formula E = mc2, an object travelling at c would have infinite mass and would therefore require an infinite amount of energy to reach c.
Now Professor Jim Hill and Dr Barry Cox in the University's School of Mathematical Sciences have developed a new way to extend Einstein's sums to understand how faster than light movement can be possible.
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.
However, neither Einstein's equations nor the new theory can describe objects moving at the speed of light itself.
'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.'
Their ground breaking research has been published in the prestigious Proceedings of the Royal Society A.
