Whatever the prof is saying in the livestream is going way WAY above my head =(

They've always been able to do so and relativity has done a pretty good job of predicting observable effects since it was first theorized.
breaking the limit of what WE KNEW was possible, but whatever, you probably understood exactly what I was trying to say but decided to act like some besserwisser.

A single experiment with a shocking result is almost always wrong. Confirmation is required.

I'm sure when the actual phenomenon is presented it will be more straightforward. Explanations/theory maybe not, but I doubt they'll even go into that yet.

Of course I've doubted light speed being the fastest thing in existence for ages so this really wasn't too surprising to me personally, but they're still going to have to continue experimenting and to confirm this.
Then, we're just going to have to wait until we find the jumpgate, wormhole and time warp technologies.

I was VERY sceptical when I read this this morning and discarded it as some sort of fault on thei end. I think odds still favor some sort of error on CERNs end but maybe theyve found something awsome. I wonder what it can mean to Physics in a longer perspective.

They did shoot neutrinos through the accelerator 16000 times since 2008 and mesaured the average time of them to be 60ns faster than what was expected.

hahaha, i'm right now studying this exact topic for my exams coming up in 3 weeks, great, now i have no motivation to study shits that potentially be all wrong, hahahahah, how irony....

It means that if what they found were prove to be right, that neutrios indeed travel faster than light, then they'll have to throw all hundred years worth of physics since almost all of our modern physics and recent centuries physics, even einstein's theory of relativity all base on the principle that the speed of light is the ultimate speed in the universe that none can travel faster than light.

Thats simply not true. Quantum mechanics still works, all other experiments still back up Einstein theory of relativity. (Your GPS still works) It just means the theory has to be corrected, because not everything in it would be wrong.
The guys who doubted they didnt measure the curvature and stuff like that, if they had watched the webcast they would just have to stfu ^^
Very interesting topic. As a third year physics student myself I'm still sceptical but very excited about this =)

The experiment has been called an extemely well done experiment by one of the visitors. The data are generally double, tripple or has more checks for accuracy.
|
So when do I get my flying car?
|
DID YOU THINK ABOUT THE MOON???
-yes
DID YOU THINK ABOUT THE ROTATION OF THE EARTH
-yes
what makes these scientists think its gonna be explained away so easily.
|
Agreed ^^
Probably they got their question out of this thread
|
gogogadget the scientists have to ensure that all the possible explanations are covered. You can't just assume that the scientists in question thought about it, because its possible that they can make a mistake and forget about that, even if its highly unlikely. So basically better safe than sorry.

I don't really see the problem. Can't we just replace "light speed" by "neutrino speed" in all documents and formulas and then everything magically works out again? :-)
What I mean is: Until now "light speed" and "max speed" was used synonymously. But if we just decouple the two and just use "maximum speed" instead with light speed being very close and neutrino speed very very close, then I don't see this breaking the existing theories.
P.S.: To explain further. "Maximum speed" could be the theoretical speed a particle of no mass could attain. As all particles have mass (even energy does, maybe neutrinos are lighter than photons?) it would make sense that photons would not attain that highest theoretically possible information speed border.
Please point out if there is an error in my logic :-)

I'll be watching this very closely, super interesting. Still seems like it'll be debunked, but I'm hoping not! The speed of light is such a pitifully slow max speed anyways. :D

It's not that easy. Because the neutrinos have mass, and the relative mass diverges as the speed increases, i.e. you can't accelerate a massive particle to the maximum speed. If photons had infinitesimal mass themselves, you're point would be valid, but as far as we know, they don't
