Hoping to have made a mistake, scientists believe they discovered a particle that travels faster than the speed of light.
Neutrino, the particle in question, traveled from Geneva to a lab in Italy 1 billionth of a second faster than light, according to a report from Reuters.
If this discovery is accurate, it will disprove Einstein's Theory of Relativity and truths in modern science that are based on the theory.
"We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't." Antonio Ereditato of the Opera collaboration told BBC News.
Though the team has measured the travel time over 16,000 times, according to the BBC report, scientists involved are looking to other colleagues to "scrutinize" their work.
