  • Gamma Ray Burst Research Reveals Fine-tuning

    Here is an article from Reasons to believe that they sent to me. It shows how the fact that the earth is a very rare planet allows life to exist on it.


    Gamma Ray Burst Research Reveals Fine-tuning

    January 8, 2015

    By Dr. Jeff Zweerink


    According to many science fiction movies, life thrives throughout the universe. Star Wars recounts long-past battles in “a galaxy far, far away.” In Contact, Ellie Arroway travels through wormholes to Vega where she encounters aliens who have billions of years of history. More recently, Interstellar depicted the search for planets in remote galaxies that could serve as a new home (after we manage to destroy Earth’s capacity to support human life). However, research into powerful gamma-ray bursts (GRBs) puts a damper on the unbridled optimism that complex life pervades the universe.

    Although scientists don’t understand GRBs in detail, they know a lot about their observable characteristics. GRBs are bright bursts of gamma rays (light more energetic than x-rays) that last from fractions of a second up to hours and emit hundreds of time more energy than a supernova. Because of the enormous amount of energy involved in a GRB, astronomers have investigated the probability of one in the vicinity of Earth and the damage a close GRB would cause.

    If Earth were close enough, radiation from a GRB would ionize our planet’s upper atmosphere and destroy its ozone shield. Consequently, the increased flux of ultraviolet light would exterminate virtually all life on the surface including marine plankton, thus depriving other marine life of a main nutrient. Some scientists have argued that a GRB explains the Ordovician extinction event roughly 450 million years ago. And research gives a 50 percent chance of a close GRB occurring in the past 500 million years. The probability increases to near certainty over Earth’s entire history! Calculations also show that any planet located close to the center of our galaxy would receive lethal doses of radiation from GRBs. Only at distances greater than 32,000 light-years does the GRB exposure probability drop below 50 percent.1

    Earth’s sees a small exposure to GRB radiation because our planet resides in a low-density region in the outskirts of a high-metallicity galaxy (astronomers consider elements other than hydrogen and helium as metals). Low-metallicity galaxies host more GRBs. The fact that the cluster containing our galaxy has only two large members (the Milky Way and Andromeda) means that the cluster includes a smaller number of low-metallicity satellite galaxies—further reducing Earth’s exposure to lethal GRBs.

    Studies of GRB rates throughout the universe also yield interesting results. Only 10 percent of large galaxies in the universe fit the criteria for hosting a planet with sufficiently low exposure to GRBs. In order to limit the number of GRBs close to a planet hosting life, a number of conditions must be met:
    1.The universe must have a cosmological constant.
    2.The universe must be at least 5 billion years old.
    3.The planet’s galaxy must reside in a small cluster with few low-metallicity satellites.
    4.The planet’s star must reside in the outskirts of a large member of the galaxy cluster.


    Earth meets all these conditions. Such a confluence of finely tuned characteristics indicates that Earth was intended to support human life. It also means that we are unlikely to find similar life elsewhere in the universe—unless God chose to create on a distant planet, too.

    Awesome, Lou. Wow, they just keep piling up the evidence. That is no coincidence.

      Random Moecular Collisions.....LOL

      From the original posted article:
      “GRBs are bright bursts of gamma rays (light more energetic than x-rays) that last from fractions of a second up to hours and emit hundreds of time more energy than a supernova.”

      Way to grab my attention Lou!
      What could emit hundreds of times more energy than a supernova?
      Naturally I had to look it up.

      Here is what I found:

      "But VY Canis Majoris is so large, many astronomers believe its fate may be even more spectacular. It may die in what is called a hypernova. These outbursts contain more energy than 100 supernovae, emitting enormous quantities of gamma rays when it occurs."
      http://www.deepastronomy.com/hyperno...s-majoris.html

      Planets that contain liquid water are said to be in the Goldilocks Zone. Not too hot and not too cold. If we found a thousand planets like our earth, that still wouldn’t mean they could contain life as we know it. The planet would still have to be fairly far away from possible hypernovas which produce GRB’s. The article hit on this.

      The perfect age of the Milky Way, perfect placement of the solar system in the Milky Way, perfect placement of the earth in the solar system, perfect mass of the earth and the perfect mix of elements in the earth defy probability. Not to mention the perfect size and distance of the earth’s moon and the perfect tilt of the earth on its axis.

      A younger galaxy has a higher probability of GRB’s. Younger galaxies generally have more stars that are massive enough to emit high end GRB’s when they collapse than older galaxies have. The more massive the star the shorter its life.

      I don’t think the earth contains the only life in the universe. Life meaning living things consisting of elements on the periodic table.
      The Holy Scripture does not emphatically state there is life as we know it in other parts of the universe or that there is not life as we know it in other parts of the universe.

      One thing we can be sure of is life as we know it is a very rare thing and life was created with a purpose by the one and only living God.

        Thanks for your replies Barry and Boabab,

        The earth is so rare that I can not believe that it is a random event, even if I would leave The Lord Jesus out of it.

        We agree on these things it seems.

        Though I tend to think that the earth is the only place mankind exists.

            Thanks Barry,

            Fred Hoyle, who was the last scientist quoted in the video, was an atheist. When he discovered that one of these numbers that the universe requires to exist, and then observed that the carbon atom had that exact number, he was so shaken that he left his lab for the day. He was aware of the fact that his discovery pointed to an intelligent creator of the universe.

            But he still refused to believe. In fact when it was discovered that the universe had a beginning and it was proven to be so, he fought against the discovery. He mocked the discovery by calling it the BIG BANG. That is the name that stuck for it.

            He fought the Big bang because he was aware that if the universe had a beginning, it had to have a beginner. Yet today it is one of the most proven discoveries of mankind.

            Yet Moses starts his book of Genesis with this:

            In the beginning God created the heavens and the earth.

            The heavens - space

            The earth - matter

            The beginning - time

            The heavens and the earth describes everything that exists in this material universe

            The beginning is the first instance of time. That is a perfect description of the Big Bang.

            And of course if the universe had a beginning - it had to have a Beginner - God
