Antonio Ereditato, professor of experimental particle physics at the University of Bern, Switzerland, is known for his proton collisions. But it is his experiment that detected faster-than-light neutrinos that could leave a wider impact.

What's special about the speed of light?

Speed of light is a universal constant, touching many areas of physics. It relates space with time and matter with energy. According to Einstein's theory of special relativity, the speed of light is constant with reference to any inertial frame. That means that irrespective of whether you are moving towards or away from the source of light, in your frame of reference , light will always travel at the same speed. Also, it is the maximum speed at which matter and energy can travel in space.

Hasn't your discovery proved Einstein wrong?

I am the director of the Albert Einstein Center for Fundamental Physics . I find him close to the definition of God. Our results show that neutrinos did travel faster than light, but it has nothing to do with disproving Einstein. Firstly, it's a finding which points to an anomaly in the theory accepted so far. Secondly , it's not yet a discovery . Different physicists will perform the experiment using different equipments to see if the results are the same.
