    Scientists at CERN, the European nuclear research agency, announced Friday morning that they had accelerated beams of protons at the world’s largest particle accelerator, the Large Hadron Collider near Geneva, to energies of 3.5 trillion electron volts. That is a new record, three times the energy of any other machine on earth, and means that the collider, after 15 years and $10 billion, is on the verge of beginning to do physics experiments. Physicists hope to begin colliding the beams by the end of the month.

    Wayyyy cool!

    Three cheers for real science!

    Real science? That's like colliding two cars head-on at light speed to see what parts fly out.
    From wiki:

    Physicists hope that the LHC will help answer the most fundamental questions in physics, questions concerning the basic laws governing the interactions and forces among the elementary objects, the deep structure of space and time, especially regarding the intersection of quantum mechanics and general relativity, where current theories and knowledge are unclear or break down altogether. These issues include:

    1. Is the Higgs mechanism for generating elementary particle masses via electroweak symmetry breaking indeed realised in nature? It is anticipated that the collider will either demonstrate (or rule out) the existence of the elusive Higgs boson(s), completing (or refuting) the Standard Model.

    2. Is super-symmetry, an extension of the Standard Model and Poincaré symmetry, realiz
    sed in nature, implying that all known particles have supersymmetric partners? These may clear up the mystery of dark matter.

    3. Are there extra dimensions, as predicted by various models inspired by string theory, and can we detect them?

    I can answer this one for a lot less that $10b. The answer is "yes". (Its a "multi-verse, not a "uni-verse") One other problem that they can't answer yet is "prove that we are really here"


    4. Are electromagnetism, the strong nuclear force and the weak nuclear force just different manifestations of a single unified force, as predicted by various Grand Unification Theories?

    5. Why is gravity so many orders of magnitude weaker than the other three fundamental forces? See also Hierarchy problem.

    6. Are there additional sources of quark flavors, beyond those already predicted within the Standard Model?

    7. Why are there apparent violations of the symmetry between matter and antimatter? See also CP violation.

    8. What was the nature of the quark-gluon plasma in the early universe? This will be investigated by ion collisions in ALICE.


    Theoretical Physics?! Astro-physics?! Grand Unification?!

    I hope they keep us posted, especially if anyone can ever prove that we actually exist.

    Our existence can only be proven by an outside intellegence. I think they want to see if we can crawl out of our primordial galaxy before they say we exist.

    Of course, blowing up the solar system with a collider might generate a little excitement. lol.

    LHC could discover things that will change all of our lives for the better.

    Let's hope so.

    New Behavior of Exotic Antimatter Particle Seen at LHC - Yahoo! News

    A rare particle containing equal parts weird antimatter and normal matter has popped up in experiments at the world's largest particle accelerator.

    Scientists recently observed new behavior of this particle, called a B meson, at the Large Hadron Collider (LHC) atom smasher, a 17-mile long (27-km) underground ring at the CERN laboratory near Geneva. B mesons are made up of one quark (the building block of protons and neutrons) and one anti-quark, which is the antimatter partner to the quark. [The Strangest Little Things in Nature]

    Granny says dem exotic particles is unstable...

    ... dey better leave `em alone an' quit messin with `em...

    ... or dey gonna blow up the world.
    :eek:

    Everyone told Chuck Yeager he would commit suicide by climbing into a jet and going supersonic. Mach 1. Pfft.

    This is but the Hadron's Mach 1.

    Pedal to the metal.
