This is the cornerstone of physics since Albert Einstein dreamed up his theory of relativity.
Einstein's Law of Relativity is one of the few scientific equations most people know -- and it's a pillar of modern physics and fundamental to the way that the universe works.
The equation states that nothing is faster than the speed of light, but one of the world's foremost laboratories says they've found subatomic particles called neutrinos that travel even faster. If their findings are proven true, it may alter our understanding of the universe.
In Einstein's famous equation, E=mc2, the constant "c" is the speed of light, which is the same everywhere in the universe: c = 186 thousand miles per second, and there is nothing faster. The constant been accepted for more than a century.
Scientists were baffled by the research findings.
As the international team which conducted the experiments puzzled over what is potentially one of the biggest upsets in history, less rigorous minds turned their attention to the possibility of time travel and visiting distant planets.
Even Professor Alvaro De Rujula, a theoretical physicist at CERN, was not immune to the excitement.
He acknowledged that if the readings proved correct, and were not the result of some human error, it created unlimited possibilities.
The average person, said Professor De Rujula, "could, in principle, travel to the past and kill their mother before they were born".
Yesterday, the scientists whose findings have force a rethink on the make-up of the universe, officially informed colleagues and asked them for help in uncovering any flaws. Link
