  • Speed of Light 'Broken' - Theory of Relativity May be Wrong?

    Speed of light 'broken' by
    scientists


    It is the most famous scientific equation of them all but last
    night it emerged Einstein's theory of relativity may be
    wrong.




    The science world was left in shock when workers at the world's largest
    physics lab announced they had recorded subatomic particles travelling faster
    than the speed of light – a feat that Einstein said was impossible.

    If the findings are proven to be accurate, they would overturn one of the
    pillars of the Standard Model of physics, which explains the way the
    universe and everything within it works.

    Einstein's theory of special relativity, proposed in 1905, states that nothing
    in the universe can travel faster than the speed of light in a vacuum.
    But researchers at the CERN lab near Geneva claim they have recorded
    neutrinos, a type of tiny particle, travelling faster than the barrier of
    186,282 miles (299,792 kilometres) per second.

    The results have so astounded researchers that American and Japanese
    scientists have been asked to verify the results before they are confirmed
    as a discovery.

    Antonio Ereditato, spokesman for the researchers, said: "We have high
    confidence in our results. We have checked and rechecked for anything
    that could have distorted our measurements but we found nothing.

    "We now want colleagues to check them independently."

    A total of 15,000 beams of neutrinos were fired over a period of 3 years
    from CERN towards Gran Sassoin Italy, 730km (500 miles) away, where
    they were picked up by giant detectors.

    Light would have covered the distance in around 2.4 thousandths of a
    second, but the neutrinos took 60 nanoseconds – or 60 billionths of a
    second – less than light beams would have taken.

    Scientists agree if the results are confirmed, that it would force a
    fundamental rethink of the laws of physics.

    John Ellis, a theoretical physicist at the European Organization for Nuclear
    Research who was not involved in the experiment, said Einstein's theory
    underlies "pretty much everything in modern physics".

    The theory, which helps explain everything from black holes to the Big
    Bang, "has worked perfectly up to now", he said.

    According to the law that energy is equal to mass multiplied by the speed
    of light squared, or E=mc2, firing an object faster than light would require
    an infinite amount of energy.

    Proof that something had travelled faster would pose major questions
    about our understanding of the laws of nature because, for example,
    something that travels faster than light would in theory arrive before it
    left.

    Will be very interesting to see how this pans out.



    Dimension-hop may allow
    neutrinos to cheat light speed




    A CERN experiment claims to have caught neutrinos breaking the universe's most
    fundamental speed limit. The ghostly subatomic particles seem to have zipped faster
    than light from the particle physics laboratory near Geneva, Switzerland, to a detector
    in Italy.

    Fish that physics textbook back out of the wastebasket, though: the new result
    contradicts previous measurements of neutrino speed that were based on a supernova
    explosion. What's more, there is still room for error in the departure time of the
    supposed speedsters. And even if the result is correct, thanks to theories that posit
    extra dimensions, it does not necessarily mean that the speed of light has been
    beaten.

    "If it's true, it's fantastic. It will rock the foundation of physics," says Stephen Parke
    of Fermilab in Batavia, Illinois. "But we still have to confirm it."

    Neutrinos are nearly massless subatomic particles that are notoriously shy of
    interacting with other forms of matter. An experiment called OPERA (Oscillation Project
    with Emusion tRacking Apparatus) sent beams of neutrinos from a particle accelerator
    at CERN to a detector in the Gran Sasso cavern in Italy, 730 kilometres away.

    The neutrinos arrived 60 nanoseconds sooner than they would have if they had been
    travelling at the speed of light, the team says.

    Supernova contradiction

    If real, the finding will force a rewrite of Einstein's theory of special relativity, one of
    the cornerstones of modern physics (and a theory whose predictions are incorporated
    into the design of the accelerators at CERN). "It's not reasonable," says theorist Marc
    Sher of the College of William and Mary in Williamsburg, Virginia.

    One problem is that the CERN result busts the apparent speed limit of neutrinos seen
    when radiation from a supernova explosion reached Earth in February 1987.
    Supernovae are exploding stars that are so bright they can briefly outshine their host
    galaxies. However, most of their energy actually streams out as neutrinos. Because
    neutrinos scarcely interact with matter, they should escape an exploding star almost
    immediately, while photons of light will take about 3 hours to get out. And in 1987,
    trillions of neutrinos arrived 3 hours before the dying star's light caught up, just as
    physicists would have expected.

    The recent claim of a much higher neutrino speed just doesn't fit with this earlier
    measurement. "If neutrinos were that much faster than light, they would have arrived
    [from the supernova] five years sooner, which is crazy," says Sher. "They didn't. The
    supernova contradicts this [new finding] by huge factors."

    Fuzzy departure

    It's possible that the neutrinos that sped to the Italian mine were a different type of
    neutrino from the ones streaming from the supernova, or had a different energy.
    Either of those could explain the difference, Sher admits. "But it's quite unlikely."

    A measurement error in the recent neutrino experiment could also explain the
    contradiction.

    "In principle it's a very easy experiment: you know the distance between A and B, you
    know how long it takes the neutrinos to get there, so you can calculate their speed,"
    Parke says. "However, things are more complicated than that. There are subtle
    effects that make it much more difficult."

    For instance, although the detectors in Italy can pinpoint the neutrinos' time of arrival
    to within nanoseconds, it's less clear when they left the accelerator at CERN. The
    neutrinos are produced by slamming protons into a bar-shaped target, sparking a
    cascade of subatomic particles. If the neutrinos were produced at one end of the bar
    rather than the other, it could obscure their time of flight.

    Sher also mentions a third option: that the measurement is correct. Some theories
    posit that there are extra, hidden dimensions beyond the familiar four (three of space,
    one of time). It's possible that the speedy neutrinos tunnel through these extra
    dimensions, reducing the distance they have to travel to get to the target. This would
    explain the measurement without requiring the speed of light to be broken.

    Antonio Ereditato with the OPERA collaboration declined to comment until
    after aseminar to be held at CERN today at 4 pm Geneva time.

    Extraordinary evidence wanted


    In the meantime, Parke is reserving judgement until the result can be confirmed by
    other experiments such as the MINOS experiment at Fermilab or the T2K experiment in
    Japan.

    "There are a number of experiments that are online or coming online that could be
    upgraded to do this measurement," he says. "These are the kind of things that we
    have to follow through, and make sure that our prejudices don't get in the way of
    discovering something truly fantastic."

    In 2007, the MINOS experiment searched for faster-than-light neutrinos but didn't see
    anything statistically significant.

    Although sceptical, he is willing to give their colleagues at OPERA the benefit of the
    doubt. "They certainly didn't do anything that's obviously stupid, or they would have
    caught that," Parke says.

    "They're smart people, these are not crackpots," Sher agrees. "But as the old saying
    goes, extraordinary claims require extraordinary evidence. This is about as
    extraordinary as you get."

      Yes I was reading this in the newspaper in the bus this morning. That Einstien theory can be wrong. But no strange, scientific theories take U-turns until it is proved like the Darvin's theory of evolution.

          The strongest explanation for this measurement which has come out so far, has been that the clocks onboard the satellites used to time the neutrinos are affected by the relativistic motion of those satellites:

              I cant read the details on this that the speed of light has been broken but heard it on news when I told it to my Physics teacher she replied that they are dumb if a car is running with the speed of light obviously the headlights of the car will project light at a double speed.

                LOL, I hope you or your Physics teacher were joking - otherwise she better get re-certified.

                Firstly, it would take an infinite amount of energy to accelerate any object to lightspeed.
                Nextly, that object would fall apart in the process, since photons are themselves the carriers of electromagnetic force which holds all objects together. (ie. if you are outracing light, then you are outracing the forces which hold objects together)

                  There are people today who think that admitting God’s absolute greatness decreases the value and importance of humans in the creation, as if God and mankind are rivals competing in greatness and power. Meanwhile I feel that whenever our perception of God’s greatness increases, with it we become greater, because we are the creation of a great God.
