  • A Crinkle in the Wrinkle of Space-time

    Updated: 2012-07-30 22:25:31
    Albert Einstein’s revolutionary general theory of relativity describes gravity as a curvature in the fabric of spacetime. Mathematicians at University of California, Davis have come up with a new way to crinkle that fabric while pondering shockwaves. “We show that spacetime cannot be locally flat at a point where two shockwaves collide,” says Blake Temple, [...]

  • Can quantum theory be improved?

    Updated: 2012-07-23 15:10:01
    (Phys.org) -- Being correct 50% of the time when calling heads or tails on a coin toss won’t impress anyone. So when quantum theory predicts that an entangled particle will reach one of two detectors with just a 50% probability, many physicists have naturally sought better predictions. The predictive power of quantum theory is, in this case, equal to a random guess. Building on nearly a century of investigative work on this topic, a team of physicists has recently performed an experiment whose results show that, despite its imperfections, quantum theory still seems to be the optimal way to predict measurement outcomes.

See , the real work isn't done by the boson itself , but by the Higgs field which theoretical physicist Peter Higgs proposed in 1964 as a means of explaining how the Standard Model of quantum physics could explain the mass shown by fundamental particles . The Higgs boson is just a physical manifestation of that
