they have meassured neutrinos at overlight speed. this might have profound effects for our understanding of physics. but be careful, einsteins theories might still be true, the same way newtons theories still are true. by this I mean, all our equations are very good approximations. so we can still use newtons equations on most cases, even tho the einstein equations are alittle bit better. in most calculations we needed to use the equations, changing from the newton to einstein would just make maybe a difference in the 10th number. that is such a small error that one usually have bigger errors from other parts (like the messurement). one only needed einsteins equations when one was calculating things where there where great forces, or great speeds. probably this discovery (if indeed correct) will lead to finding the limit of einsteins equations. they will not be invalidated, but will no longer be thought of as as universal as they were. futhermore it has been known for a long time that einsteins equations were not completely correct, they had a discrepancy when meting quantum physics. this is why people have been searching for the unifying theory of physics for many years. this discovery might be an important steppingstone on the way there. also, it might all just be a meassuring error |

at 5:38 AM, Friday September 23, 2011 EDT dont know how they time it, but 60 nanoseconds is pretty long. shortest time interval measured is 100 attoseconds.

at 4:20 PM, Friday September 23, 2011 EDT I have never understood why lightspeed is believed to be the ultimate limit anyway, so I'm kinda not suprised. Surely, it is great to base formulae on, but that's hardly a proof that something faster than light can't exist.

at 4:54 PM, Friday September 23, 2011 EDT Light speed was presumed to be the cosmic speed limit bc light has no mass. In order to go faster you'd have to have negative mass (or if photons have mass, less mass than photons).
