"Now we are 100% sure that the speed of light is the speed of neutrinos."

how can neutrinos travel at light speed if they have mass?

>> No.4473108

because magnets

>> No.4473110

Because you are reading science articles on something other than a journal.

Because highly relativistic particles can travel at 99.999..% the speed of light so for a timing experiment it's impossible to see the 0.00...1% difference. The errors would be much larger.

>>4473128
easy to measure the diff because of time dilation in frame of particle

Shitty journalists giving a bad name to science.

I would have expected that they follow a Gauss distribution, with most of them more or less at light speed, some of them slower and some of them faster.

>>4473133
yes but we can't measure in the frame of the particle.

I don't think so Tim
