QuoteThe particle, whose existence has been predicted by theoreticians, would help to explain why matter has mass. Finding the Higgs is a major goal of Cern's Large Hadron Collider (LHC). But the US Fermilab says the odds of its Tevatron accelerator detecting the famed particle first are now 50-50 at worst, and up to 96% at best. Both machines hope to see evidence of the Higgs by colliding sub-atomic matter at very high speeds. If it exists, the Higgs should emerge from the debris. The LHC has been out of action since last September when an accident damaged some of the magnets that make up its giant colliding ring. Project leader Lyn Evans conceded the enforced downtime might cost the European lab one of the biggest prizes in physics. Cern and Fermilab officials squared up at the American Association for the Advancement of Science (AAAS) annual meeting in Chicago.
QuoteThe beams have not yet been run continuously. So far, they have been stopped, or "dumped", after just a handful of circuits. By Wednesday evening, engineers hope to inject clockwise and anti-clockwise protons again, but this time they will "close the orbit", letting the beams run continuously for a few seconds each. Cern has not yet announced when it plans to carry out the first collisions, but the BBC understands that low-energy collisions could happen in the next few days.
QuoteBecause these two photons are entangled, the act of detecting the second as either a wave or a particle should simultaneously force the other photon to also change into either a wave or a particle. But that would have to happen to the first photon before it hits its detector -- which it will hit 50 microseconds before the second photon is detected. That is what quantum mechanics predicts should happen. And if it does, signaling would have gone backward in time relative to the first photon.
