Faster than light particles found, claim scientists

Scientists at the Gran Sasso facility will unveil evidence on Friday that raises the troubling possibility of a way to send information back in time, blurring the line between past and present and wreaking havoc with the fundamental principle of cause and effect.

“The constancy of the speed of light essentially underpins our understanding of space and time and causality, which is the fact that cause comes before effect. Cause cannot come after effect and that is absolutely fundamental to our construction of the physical universe. If we do not have causality, we are buggered.”
- Subir Sarkar, head of particle theory at Oxford University
