That's great guys, really appreciate all the input here. What's the governor that keeps em rolling along at just under the speed of light? Has anyone proved this? I mean, what if they do have no mass, what could make them change state?

A neutrino is similar to a photon and does travel at the speed of light
After super nova 1987A the neutrinos preceded the visible light for 70,000 years.
A neutrino lives with one dimension less than a photon that is the reason it leaves the super nova first and passes through the earth so easily.
The quantum effect gives the neutron a third dimension occasionally,and the reason we can detect the odd one after trillions pass through the earth.

The mass of a neutrino is small enough that any measurable amount of kinetic energy means that they travel very close to light speed. Since we only actually measure the energy of the neutrino, and the theory at the time said they should be massless, they were thought to actually go the speed of light. Now, it appears that they have mass (again, theoretical: we actually only meaure the oscillations between neutrino types and apply a theory) and go just a small amount less than the speed of light.

Neutrinos travel at CLOSE TO the speed of light and have a mass so small that it was thought for a long time they were completely massless.
So, no physical laws have been broken.

Bro, they dont travel "exactly" at the speed of light.
If they do, then the experiment suggests that the mass of the neutrino as negligible.
But, if you apply Einsteins relativity theory, It will not reach the speed of light. Maybe 0.99999999999999999(add infinite 9 here)...c, but not equal to the speed of light.

They don't travel at the speed of light.
According to Einstein theorem, any moving matter would have a "mass-expansion" as they move. The closer they are to the speed of light, the bigger the expansion.
Unfortunately, when they reach the speed of light (v=c), the equation goes kaputtzzzz (division by zero). So, if anything could travel at the speed of light, that anything must be "mass-less" to begin with.
This explain the foton (light-particle). They travel at the light of speed (duh...) and they have no mass.
Of course, the science would continue to evolve. There might be a loophole in Einstein Theorem that we don't know yet.
Hope this helps

neutrinos have neither been proven to have, or not have mass. this issue is still up for debate. furthermore, anything that has mass cannot travel at the speed of light. hope this helps!!!!

Simple ... they don't travel at the speed of light.
