Let's say you were going only 1km/h slower than the speed of light relative to some observer. If you shoot a rifle along your direction of motion what would the stationary observer see? The intuitive answer would be that he would see the bullet moving at C - 1 + Sb where C is the speed of light and Sb the speed of the bullet (all in km/h).
Einstein said the above was false. This can be put to the test in a particle accelerator. Particles are accelerated to say 99% the speed of light and then more enertgy is added. It's been clearly observed that the added energy assimptotally (hmm is that a word) increases the speed closer and closer to C, but no matter what you do the threshold can't be broken.
That's been clearly observed, as well as put to the test in several different types of experiments. Not to mention that Electromagnetic waves (radio, light, satalite signals) all move at this speed.
Now this neutrino news MIGHT have something to it. Neutrino's literally pass through our entire earth and hardly interact with anything, so they are indeed strange.
This does NOT mean Special Relativity (which is clearly not well understood by most) should be thrown out of the window, what to speak of General Relativity which has provided incredible predictions and has been scrutinized. General Relativity is a thing of beauty and is quite rigorous mathematically, so even fewer understand this I would say.
