Neutrino's have no mass, right? No mass, no problem with FTL.

Well, there are plenty of cases in which particles can go faster than light, in the sense that in certain mediums, neutrinos can pass through without interaction while photons do not. Take for instance a neutrino leaving the core of the Sun. The neutrino will leave the photosphere of the Sun before the light energy from the core will. Why? The neutrino will hardly interact, if at all, with any of the matter within the Sun’s interior, while the light will get absorbed and re-emitted. I will assume that this article is referring to the speed of light in a vacuum, however, and feel that that is probably an improvement. However, I would like to hear on the news if we can ever develop some way of moving matter through hyperspace, or something of the sort, so that we can go faster than light and visit other Stars. But then again, that’s my sci-fi/fantasy section of my brain running again!

Photons have no mass either, and are of course restrained by light speed.

Actually, Neutrinos do have a very VERY small mass.

I recommend the book Neutrino by Frank Close. Really good overview of the history and science of the Neutrino.

Neutrinos almost have no mass, but not quite.
