What.

If this turns out to be true... I will weep a river of joy.

Read about this a few days ago, I believe, and it's definitely interesting. There are already numerous theories that point to our perception of the laws of physics to be at least somewhat incorrect. The only problem is, with stuff like this, even the smallest error can seriously skew the results. Interesting nonetheless; leaves you with a little to think about.

Neutrino surfing time?

Probably a measuring error though.

Bah, downers, if this ends up to be true it will likely be the greatest discovery of our time.

Just being realistic. I'd love for it to be true, but there are too many opportunities for error and the implications of it being true are pretty radical.

The thing is, CERN has been testing this thing for errors for years, and only now they decided to come out and say "gently-carress it, you guys see what we did wrong."

Radical is an understatement.

If you want to be realistic, then you know everything science is just a theory. Its the Theory of Relativity. Einstein was really really smart, but he didn't hold the secrets to the universe. I think they may have actually found something that broke the barrier.

Theory in the scientific sense is not the same as the colloquial use. General relativity has been confirmed in myriad experiments and is used in all sorts of technology. Global positioning systems and pretty much all cosmological observations or predictions rely on it to be accurate.

Meanwhile, one study apprehensively suggests neutrinos may be capable of moving faster than C. I think it's a fairly safe bet they made a mistake.

Our scientific knowledge changes constantly, as it always has.  If we've indeed broken the speed of light barrier, then we'll start opening an entire new realm of possibilities.  That said, breaking the speed of light in no way invalidates what we've already learned.  GPS systems are not going to magically become inaccurate just because this discovery was made.

I'm aware our scientific theories are incomplete at best, are always being refined. But refining isn't what would happen if these observations are confirmed. You'd have to throw out the entirety of general relativity. E would necessarily not equal mc^2.

Looks like it may have been GPS itself that caused the error.

Edit: Well... not really caused. Just read it.

gently-carress! You guys had to crush my hopes.

Don't worry.  They have measured light travelling through fiber optic cables faster than the speed of light.

Fun part is while the light actually arrived at the end of the cable before it was supposed to be able to the data carried by the light always took the correct amount of time.  Fun stuff. :P

If he's talking about what I think he's talking about, it has to do with phase velocities of certain frequencies of light being greater than C in certain materials, and it's not really all that special. Especially because, as he said, no information is transmitted.

So there's likely not any mainstream news articles about it, but you'll probably find something if you dig through Google Scholar.

Yeah something like that.  I don't have a link or anything handy but it's been going around for a couple years now.
