Hugh Ross: ET blocks Carl Sagan’s calls

Spread the love

From Hugh Ross at Salvo:

During my graduate school days at the University of Toronto (late 1960s) I took a short summer course, Advances in Planetary Physics, taught by astronomer Carl Sagan. Sagan was a rising star then and well on his way to becoming the science popularizer and communicator for which he later became famous. Most of the course and nearly all of the informal evening discussions focused on the possibility that extraterrestrial intelligent life existed and on the kinds of civilizations such beings would have established. In Sagan’s mind, there was absolutely no doubt that extraterrestrial intelligent beings (ETI) existed. Furthermore, he was convinced that on many planets in our galaxy ETIs had developed civilizations far more technically advanced than ours.

In many respects, SETI research is a waste of time, money, and talent. However, these latest SETI efforts are yielding greater insights into and appreciation for just how many plans, preparations, and preliminary steps—especially the carefully orchestrated introduction of certain forms of non-intelligent life—are needed to make possible a narrow time window during which an intelligent living species can exist on a planet, and how many more plans, preparations, and carefully orchestrated steps must be taken to enable such a species to launch and sustain a high-technology civilization. No such species and civilization are possible apart from the handiwork of a super-intelligent, super-powerful, super-benevolent Creator.6 If there is intelligent life elsewhere in the universe, it exists thanks to the miraculous interventions of that Creator.

    a few notes:

    Linked from Appendix C from Dr. Ross’s book, ‘Why the Universe Is the Way It Is’;
    Probability Estimates for the Features Required by Various Life Forms:
    Excerpt:
    Requirements to sustain bacteria for 90 days or less:
    Probability for occurrence of all 501 parameters approx. 10-614
    dependency factors estimate approx. 10^-303
    longevity requirements estimate approx. 10^22
    Probability for occurrence of all 501 parameters approx. 10^-333
    Maximum possible number of life support bodies in observable universe approx. 10^22
    Thus, less than 1 chance in 10^311 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracles.

    Requirements to sustain unicellar life for three billion year:
    Probability for occurrence of all 676 parameters approx. 10^-859
    dependency factors estimate approx. 10^-303
    longevity requirements estimate approx. 10^22
    Probability for occurrence of all 676 parameters approx. 10^-578
    Maximum possible number of life support bodies in observable universe approx. 10^22
    Thus, less than 1 chance in 10^556 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracle

    Requirements to sustain intelligent physical life:
    Probability for occurrence of all 816 parameters approx. 10^-1333
    dependency factors estimate approx. 10^-324
    longevity requirements estimate approx. 10^45
    Probability for occurrence of all 816 parameters approx. 10^-1054
    Maximum possible number of life support bodies in observable universe approx. 10^22
    Thus, less than 1 chance in 10^1032 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracle

    Anthropic Principle: A Precise Plan for Humanity By Hugh Ross
    Excerpt: Brandon Carter, the British mathematician who coined the term “anthropic principle” (1974), noted the strange inequity of a universe that spends about 15 billion years “preparing” for the existence of a creature that has the potential to survive no more than 10 million years (optimistically).,, Carter and (later) astrophysicists John Barrow and Frank Tipler demonstrated that the inequality exists for virtually any conceivable intelligent species under any conceivable life-support conditions. Roughly 15 billion years represents a minimum preparation time for advanced life: 11 billion toward formation of a stable planetary system, one with the right chemical and physical conditions for primitive life, and four billion more years toward preparation of a planet within that system, one richly layered with the biodeposits necessary for civilized intelligent life. Even this long time and convergence of “just right” conditions reflect miraculous efficiency.
    Moreover the physical and biological conditions necessary to support an intelligent civilized species do not last indefinitely. They are subject to continuous change: the Sun continues to brighten, Earth’s rotation period lengthens, Earth’s plate tectonic activity declines, and Earth’s atmospheric composition varies. In just 10 million years or less, Earth will lose its ability to sustain human life. In fact, this estimate of the human habitability time window may be grossly optimistic. In all likelihood, a nearby supernova eruption, a climatic perturbation, a social or environmental upheaval, or the genetic accumulation of negative mutations will doom the species to extinction sometime sooner than twenty thousand years from now.

    Thats the problem with toronto. Having Sagan like people paid to teach the kids stupid things because they are based on no good reasons.
    Biology has nothing to do with cosmology stuff. NOTHING.
    Cosmology does not teach biology is likely based on probability of lights in the sky.
    Its not intelligent relative to what it should be.
    What did Carl Sagan ever accomplish worthy to be on a list of 21 century accomplishments in science?? Even a top ten thousand list?
    Its sad for him and all of us to die and i wish he was here but he is used to promote dumb and wrong ideas.

    But his widow Mr. Byers had some honest things to say about biology. Lynn was a biologist after all. What she had to say didn’t make any of the Darwinists happy, but sadly she held on to her naturalism until she died.
