Was Earth a Migratory Planet?

astroengine writes "Why our planet isn't a "snowball Earth" — a dilemma called the 'faint young sun paradox' — has foxed solar and planetary scientists for decades. Since the Earth's formation, a planet covered in ice should have stifled any kind of greenhouse effect, preventing our atmosphere from warming up and maintaining water in a liquid state. Now, David Minton of Purdue University has come up with a novel solution that, by his own admission, straddles science fact and fiction. Perhaps Earth evolved closer to the Sun and through some gravitational effect, it was pushed to a higher orbit as the Sun grew hotter. But watch out, if this is true, planetary chaos awaits."

    In fact, Earth received a Blue-green card as early as 3.5 billion years ago after passing a solar naturalization test.

    "And then a miracle occurs" makes a good punchline but lousy science.

    It is the consensus of 99% of climatologists that the earth isn't a snowball and therefore it is a fact that the earth has slowly moved into a higher orbit at exactly the same rate that the sun has warmed so as to maintain a climate on earth appropriate for life. The more we fill the atmosphere with greenhouse gases and thus heat the earth, the further the earth will move away from the sun so as to maintain an optimum climate. These "inconvenient truths" prove that there is an intelligent designer of the universe.

      Dude, if you can get a creationist to accept enough science to admit that anthropogenic global warming is real, that miracle itself is enough to prove the existence of God.

      Perhaps you should re-read the canon.

      Book Secondi 3:12

      Lo, for the baking of the divine meal
      Let it be done that the goliath meatball[1]
      Be moved upon the table[2]
      At such distance that the woodfire oven[3]
      Provides a strong heat source to allow for the Maillard reaction
      To properly crustify the goliath meatball
      And then let it be moved
      To a sufficient distance, where it may
      Yet leave the inside full of tenderness
      Like the twin meatballs upon the bosom of a mother
      His Noodly Appendage shall make such adjustments
      Necessary to make it so.

      Ramen

      [1] the goliath meatball being our planet.
      [2] the table, sometimes mistranslated as "the firmament", is of course, the fabric of spacetime
      [3] there is some disagreement among scholars about this translation, but we know from context that this is the sun

      Clearly, from analysis of scripture, we can determine that the Master of the Heavenly Forkful moves or planet into a lower or higher orbit to ensure that it cooks properly.

    Let's see - the Mantle is a hard shell around a liquid core. Marrow is a rich edible substance scraped from inside bones that has a solid or semi-solid consistency but softens when heated (cooked)...
