    Advanced Civilizations in the Universe - A Galaxy Insight

    "Biologically based technological civilization...is a fleeting phenomenon
    limited to a few thousand years, and exists in the universe in the
    proportion of one thousand to one billion, so that only one in a million
    civilizations are biological."

    Steven J. Dick, NASA Chief Historian

    If extraterrestrial intelligence exists, Stephen Dick concludes in an
    article in the International Journal of Astrobiology, it has probably
    evolved beyond biology to an advanced form of artificial intelligence that
    is the product of million or billions of years of technological and cultural
    evolution similar to the civilizations Arthur C Clarke envisioned that
    created the Tycho Monoliths in 2001 -A Space Odyssey. In a post-biological
    universe machines are the dominant form of intelligence.

    o Dick the emergence of life and the evolution of intelligence is literally
    pre-programmed by the laws and constants of physics, which function similar
    to cosmic DNA.

    The emergence of life and intelligence, according to Dick, was coded into
    the cosmic playbook from the first moment of the Big Bang. Intelligent life
    is destined to eventually dominate the cosmos and ultimately to serve as the
    instrument of cosmic replication.

    In his book, The Biological Universe: The 20th Century Extraterrestrial Life
    Debate and the Limits of Science, Dick argues that at the dawn of the 21st
    century calls for us to take into account the Copernican principle that life
    on earth and humanity is in no way physically central in the universe: "we
    are located on a small planet around a star on the outskirts of the Milky
    Way galaxy."

    The first concept, the question of life beyond our home planet, Dick
    explained in his essay, has exercised human imagination, and has stirred
    irrational fears, since the ancient Greeks, fears that in large part were
    responsible for the death more than 400 years ago, on February 17, 1600,
    when Giordano Bruno was summoned from his Inquisition prison cell in Castel
    S'ant Angelo across the Tiber from the Vatican, marched to the Campo dei
    Fiori, and burned at the stake in large part for his belief in an infinite
    number of inhabited worlds. So anathema, Dick writes, was the subject of
    other worlds that even historians of science avoided it until the 1970s.

    This worldview of the cosmos as a biological universe is a revolutionary
    perspective as profound a revision in our way of think as the Copernican and
    Darwinian revolutions. It is a worldview that believes that "planetary
    systems are common, that life originates wherever conditions are favorable,
    and that evolution culminates with intelligence."
