Merged Puzzling results from CERN

So if verified we're talking about a Comparatively Rare circumstance in which C can be exceeded by a Tiny Amount.

Any idea what tweaks would be needed, to bring General Relativity back into line with observed Reality?

Feel free to Extrapolate Wildly.

Is there anything here for String Theorists?

I think these neutrinos are just in a giant hurry to get to one of Berlusconi's "bunga bunga" parties while they're still going on.
 
It has been a few years since I read a textbook on SR--or posted here for that matter--, but I was explaining this to a friend yesterday, and realized(perhaps incorrectly, since no one in these articles seems to be saying this) that a c violation wouldn't look like this at all?

Technically, wouldn't any neutrino which broke lightspeed disappear in any future reference frames? As in, we wouldn't be seeing them get there faster than c; they mysteriously would appear to not arrive at all on the arrival end of the experiment. If we then repeated the experiment with the detector in the same room as the emitter(sorry if I am using crude terms), we might see them arrive from the future instead, before we even shot them out!?

In any case, it wouldn't just look like they were faster, unless there is some kind of impossible stable wormhole under the mountains out there that allowed them to skip forward.

c isn't the fastest car on the block pending our finding a new one, it is the absolute top speed possible before you start not being a part of the time-forward universe we all live in.

Or, am I totally wrong here?
 
The high-accuracy time-transfer GPS receiver allows to continuously monitor tiny
movements of the Earth’s crust, such as continental drift that shows up as a smooth variation of
less than 1 cm/year, and the detection of slightly larger effects due to earthquakes. The April
2009 earthquake in the region of LNGS, in particular, produced a sudden displacement of about 7
cm, as seen in Fig. 7. All mentioned effects are within the accuracy of the baseline determination.
Tidal effects are negligible as well.

That's a pretty darn accurate GPS. Even without the violation of c, this kind of accuracy is amazing.

Well, that was fast:

The IT Security guys were running an unapproved software scan at the time.

At least, that's what is always happening when the timing on my computer goes wonky during the busiest time of the day (still don't understand why they have to do these things in the middle of the work day...every time).

That way they can make sure your computer is on...

Music certainly contains information. But I'm extremely skeptical of the claim that music was transmitted faster than the speed of light. Do you have a cite for that?

It was a while ago, but I'll see if I can find more.

Here's a forum discussion on it on The Straight Dope. It was a NOVA program so I'll go find that.


Here's the transcript and the pertinent part quoted here:
NARRATOR: In this experiment, Guenter Nimtz splits a microwave signal in two. Half goes through the air, traveling at the speed of light, and half is fired into a barrier to block the signal. But that's not what happens.

GUENTER NIMTZ: This is the oscilloscope where you see the signal and then we can see which one is faster.

NARRATOR: The two humps on the screen are not in the same place because the microwaves that went through the barrier got to the detector first - apparently exceeding the speed of light.

GUENTER NIMTZ: Only a very small part comes to the other side, but it comes and this part comes at the velocity which is much faster than the velocity of light.

NARRATOR: So how could the microwaves go faster than light - and what was the role of the barrier? Nimtz chalks it up to a strange phenomenon called quantum tunneling. At the subatomic or quantum level, the world is ruled by probability and chance, and the seemingly impossible occurs all the time. For example, when a stream of particles like photons meets a barrier, most bounce off. But a few of them materialize on the far side of the barrier and continue on their way. Nimtz detected the particles that appeared, and measured how fast they got there.

GUENTER NIMTZ: And the news about this we did this for fun, and when we figured out that it's faster than the velocity of light we did not think about its importance.

NARRATOR: Another expert in quantum tunneling is Raymond Chiao. He agrees with at least part of what Nimtz has found.

RAYMOND CHIAO: In our experiments we have measured that a single photon can tunnel across a tunnel barrier at 1.7 times the speed of light.

NARRATOR: What bothers Chiao is not that random photons seem to go beyond the speed of light, but that Nimtz claims he can use tunneling to send information faster than light.

RAYMOND CHIAO: To have a genuine signal you really have to control the signal, but in, in quantum mechanical tunneling it's a completely random process. Fundamentally we cannot, we cannot send information with this tunneling particle.

GUENTER NIMTZ: Yeah, some colleagues are claiming that you cannot send information and then we started to transmit Mozart 40 and this is for instance the original tape. That's what we sent at a speed of 4.7 times the velocity of light and a distance of about 14 centimeters, whether you can recognize Mozart 40 or not.

NARRATOR: Despite the randomness and uncertainty of the tunneling process, Mozart seems to have gone through the barrier.

Photons interact with electrically charged particles and the speed of light is related to electromagnetic properties of the vacuum.

Neutrinos only interact via the weak force. Shouldn't neutrinos have a (max) speed related to the weak properties of the vacuum?


Just thinking out loud...

Because you've misunderstood Cherenkov Radiation:

electrons never exceed the speed of the universal constant c.

Thanks for playing. I am very new to all of this.

Fact: Neutrinos are supposed to travel at the same speed whereas light can be slowed down by the medium it has to travel through.

Are these test performed in a vacuum? Are there cables connecting point A to point B?

The speed of light is a lot more than just the speed light goes at. It's the speed of gravity for example.

It really is a fundamental speed limit for anything.
