What's the deal with neutrinos? Do they exceed c or what?

Yes. Its confirmed.


Quantum physics are counter-intuitive and extremely weird already, but I`m sure this will open new possibilites for discovery.

I actually gave a presentation 3 weeks ago, why the OPERA results violate special relativity and why it will turn out to be a measurement failure. I'm looking forward to see what happens now :D
In reality, I'm a big fan or starting from scrath with new ideas.

>> No.4046518

yeah if something were really discovered to travel faster than c, then you'd think they would make a bigger deal about it. Sounds like they did something wrong.

>> No.4046520

OPERA confirms they didn't know how to account for general relativity due to the difference in gravity between CERN and detector. Scientists marvel in the concept as they have just seen it for the first time.

Emma Stone guy! I'd like to ask you a thing that's been bugging me for a while. I've been attending a rel. quantum mechanics course and one of the first things they told us is that the klein gordon equation gives rise to negative energies. The way they justify that is by solving E^2=p^2+m^2 for E. My question is: shouldn't these negative energies be something that should arise in special relativity as well? My troubling probably has to do with my professor's explanation.

In 1997 a humanzee called lauren was walikng in a forest and then a she just dissapeared no one ever found her untill 2000 when a yoing girl called Mary found her body and markings on her chest saying: I wasnt pretty enough" and now you have read this she will appear in your mirror saying your not pretty enough and kill you. by the way the girl called mary died shortly after.

To be saved paste this to 5 other thread. THIS TRUE
this true

>> No.4046542

There are results that make it appear like they traveled faster than light in certain experiments.

This does not mean they do. It just means there is an effect nobody has figured out an explanation for yet.

Making grand proclamations that "relativity is wrong" is stupid for several reasons. One, it's really, really, really premature. Two, even if they are somehow arriving before they leave (as they would need to), that doesn't mean relativity is wrong, it just means it's incomplete, AS WE ALWAYS KNEW IT WAS.

So basically, everybody calm the fuck down.

Good thing such a thread is up. What would happen if it is 100% confirmed that they are faster than light? Would it mean anything?

Of course it would mean SOMETHING. It would, at the very least, mean a particle exists that travels faster than light.

We don't know what it would mean. Probably some weird quantum trickery.

no the experiment was rerun to reduce errors but any systematic error in the timing system would still affect the result.
both experiments were run with OPERA.

Maybe the curvature of the earth threw off the clocks with it's spin.

No, it's worse than that. All of the clocks in ONE PLACE would have to be wrong, compared to ALL the clocks in the OTHER place. A systematic clock incorrectness is not even enough.
