RE: A final song for OPERA: 6 years of neutrino data, nice events and an exemplary open data policy
I am not sure to follow the question. I will however try to answer. Special relativity is our framework, not classical mechanics. As a consequence, any massless particle travels at the speed of light and their motion is far from being zero.
There are for now no other known massless particles besides photons and gluons (as gravitons have not been discovered yet; will they ever be?).
Makes perfect sense then. Thanks for taking the time to respond and yes, you did answer my question :)
So gravitons are assumed to be traveling at the speed of light? I believe there's a lot to come in the future given the rate at which technical knowledge is produced every year.
Gravitons, if they exist, would be massless and thus travel at the speed of flight. This is correct. The problem is that is is not clear they exist :)
