    Ah, it's allright. Einstien was scrutinized and scoffed at too. In a seemingly boundles and endless universe, I never really thought that light was the fastest thing around. *But I guess it still is. Overactive imagination. :/

    Yea, it would really screw the physics world over. This is like disproving gravity.

    I think I'll start showing up to meetings a fraction of a second early, that will upend all of the theories that abound in the office :laugh:

    Well, the scientific community got over the "world is flat" and "earth is center of the universe" ideas. I'm sure we will survive this with less fanfare.

    A lot of theories are based on the fastest thing possible being the speed of light. This has the punch to make all those theories null and void, which is like putting a big cross through peoples LIFE long work.

    Saw that earlier on my droid... that's just awesome.... It's these kinds of discoveries (if it's correct) that give us huge leaps forward....

    No not really. Because even if Light isn't the fastest thing in the universe it is still a constant. Therefore almost all mathematical equations using "c" still apply true. It's just throws a fork in the gears for anything beyond speed of light and only in relation to particles with very little to no mass.

    Getting something to move FTL will still require the same energy as it always had and anything we create isn't going to have a mass even close to a neutrino. So really this only affects super sub atomic particles, in a Vacuum.
     
    WhiteLotus says thanks.

    thespeed is actually super close, so maybe just a new lightspeed thats accurate

    ah yea, that's true. Still, if one were to label a neutrino particle with a message, you could then (I think) send it forward in time. Crazy shit.

    The biggest implications are quantum computing. get a answer before you ask the question.....?

    Possible I guess, as long as the message doesn't change the mass of the neutrino. The neutrino itself has less mass than a single electron. Has no charge + or -.

    Like you said. Crazy shit happens at the sub atomic level. I can barely grasp some of the concepts. Entanglement...That is crazy stuff and blows my mind. Just by observing the particle changes the behavior...

    Who's to say our perception of the 4th dimension is even remotely accurate. We can only measure the 4th dimension in our 3rd dimensional minds that can only perceive the 4th dimension in a slide show.

    Einstein estimated that the speed of light was equal to c in E=mc^2. It was impossible for him to prove the exact value of c, only that it is really big. It is possible that his estimate is off a little or there is another layer to the riddle that has yet to be uncovered.

    Yeah but we know and can measure the speed of light. He was right on. Light is nothing more than a wave. If you know the Energy and you know the Mass, speed of light is easy to figure.

    Sq.Rt (E / M) = C

    Where E = Joules.

    So you're saying faster than light speed would mean time travel, then?

    Whatever happened to spooky action at a distance (quantum entanglement)?
    Also, I know it violates super-symmetry but I like my tachyon beams: scanning something before you ever thought to start scanning it.

    . . . Haven't read article yet . . .

    Although I'm not who you were replying to, yes. :laugh:

    Rather, traveling back in time. Traveling forward in time is trivial, just get on a plane. If you're not following me then start complaining to your GPS. :D

    Traveling faster than light relative to a certain region of space will make you travel back in time relative to that space. AFAIK . . .

    the time difference is 60 nanoseconds or 60 feet at the speed of light, total distance is 730 km.
    error of the experiment is 10 ns

    doesnt the earth get stretched by the moon? wouldnt this invalidate whatever distance measurement they have? anyone know how much the earth gets stretched and able to apply some math to that distance?

    best info in this article:
    http://www.nature.com/news/2011/110922/full/news.2011.554.html

    webcast at 4 pm cet tomorrow @ cern

    and there's the paper: http://arxiv.org/ftp/arxiv/papers/1109/1109.4897.pdf

    meh

    Multi-band GPS in CMR format, I know 8 places of dual band will return less than 2cm of error over 2 weeks. Add in Glonoss and you reduce that to less than 1cm, two sigma over years.

    What about the speed of the earth through space, and the rotation of the earth, the speed of the galaxy? Surely they included those measurements in their allowances. Earth is hurtling not only around, but around the sun, around the galaxy, and away. What are the effects of pushing massed objects to the speed of light, are the no longer influenced by the forces that constrain all other matter, thus being able to seemingly travel faster than light?

    in vacuum or in medium?

    Neutrino oscillation is a barely studied process, people even don't know the mass of neutrino. If neutrino appears to be a WIMP then indeed it can exceed the speed of light.

    Neutrino, you are a hero of freedom, I bet you ain't from this world. So where are you going?

    no. nothing can exceed the speed of light.
