  • A Universe From Nothing

    [youtube=http://www.youtube.com/watch?v=7ImvlS8PLIo]

    Lawrence Krauss at the Atheist Alliance International 2009, gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing. Krauss is the author of many bestselling books on Physics and Cosmology, including “The Physics of Star Trek.”

    This is, by far, the best talk I’ve had the pleasure to listen to. It is a bit long so, if you don’t have much time to listen to the whole talk now, at least listen to this excerpt, it’s just one minute long.

  • Astronomy Picture Of The Day | Melotte 15 in the Heart

    Explanation: Cosmic clouds seem to form fantastic shapes in the central regions of emission nebula IC 1805. Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula‘s newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are near the center in this colorful skyscape, along with dark dust clouds silhouetted against glowing atomic gas. A composite of narrow and broad band telescopic images, the view spans about 40 light-years and includes emission from hydrogen in green, sulfur in red, and oxygen in blue hues. Wider field images reveal that IC 1805’s simpler, overall outline suggests its popular name – The Heart Nebula. IC 1805 is located about 7,500 light years away toward the constellation Cassiopeia.

  • Heaven

    Fish (fly-replete in depth of June,
    Dawdling away their wat’ry noon)
    Ponder deep wisdom, dark or clear,
    Each secret fishy hope or fear.
    Fish say, they have their Stream and Pond;
    But is there anything Beyond?
    This life cannot be All, they swear,
    For how unpleasant if it were!
    One may not doubt that, somehow, Good
    Shall come of Water and of Mud;
    And, sure, the reverent eye must see
    A Purpose in Liquidity.
    We darkly know, by faith we cry,
    The future is not Wholly Dry.
    Mud unto mud! – Death eddies near –
    Not here the appointed End, not here!
    But somewhere beyond Space and Time,
    Is wetter water, slimier slime!
    And there (they trust) there swimmeth One
    Who swam ere rivers were begun,
    Immense of fishy form and mind,
    Squamous, omnipotent, and kind;
    And under that Almighty Fin,
    The littlest fish may enter in.
    Oh! Never fly conceals a hook,
    Fish say, in the Eternal Brook,
    But more than mundane weeds are there,
    And mud, celestially fair;
    Fat caterpillars drift around,
    And Paradisal grubs are found;
    Unfading moths, immortal flies,
    And the worm that never dies.
    And in that Heaven of all their wish,
    There shall be no more land, say fish.
