Just go buy an iphone and you'll feel better.

I don't understand. Just swap out the c's for something else ever-so-slightly more than c and boom done. Sounds like it gets violated all the time as it is anyway. lol very special relativity?

Some new news, they were able to replicate it with some changes.

Speed of light is like rock. Nothing beats rock.

I still like the theory of it not being the neutrinos they were supposed to be measuring but a tachyon travelling through time backwards. Relativity would still work and we would have discovered a new particle.

The wiki link helps. I saw it suggested on reddit that Neil DeGrasse Tyson did, but he just suggested it as a possibility and thought equipment error was the most likely reason (this was before the second confirmation). From there I had a fb convo with a guy I was in my UG physics program with who went on to get his PhD, so that's where the majority of my information comes from. Personally, I can barely conceive of it as a theory, much less explain it. I have forgotten most of the little I knew about particle physics since graduation 8 years ago.

They discounted it because the neutrinos didn't act the way they thought neutrinos would act traveling faster than the speed of light?

Agreed, I loled. Their reason for rejecting it doesn't seem right to me. Since theoretically nothing was supposed to travel faster than light, them rejecting the finding because "they would have lost energy had they gone faster than light, but they didn't, so they didn't go faster than light" seems pretty

to me.

I mean, all of this has been theoretical up until now, so how do they know how a particle traveling faster than light would react? It wasn't supposed to be possible at all!

Strange.

Anyone know when a test by a different team of researchers is scheduled to try to replicate these results?

This guy is saying many Physicists believe the speed of light was not broken and it was system error (start at 3:11)

Does anyone know which position most Physicists take on this issue?

There's absolutely no question that the vast majority of physicists think it's a mistake. Even the people who did the experiment essentially presented it as "Hey, please find the mistake."

Even people that did the experiment believe it is an overlooked or unforeseen systematic error of some kind because that is just startospherically more likely than the speed of light was exceeded.

You must plan on having sex with a woman because everyone knows you're faster than the speed of light in the bedroom. Baaazzing!

His example of systematic error with GPS doesn't make sense to me. He's saying that:
neutrino faster than light -->
relativity needs to be adjusted -->
GPS needs to be adjusted -->
Measurements of original experiment need to be adjusted -->
neutrino probably didn't go faster than light.

But then that last conclusion means relativity DOESN'T need to be adjusted... and the whole argument circles back again to neutrino actually did go faster than light...

I'm confused.
