Researchers Complete New Gondwana Map

An anonymous reader writes "A new computer simulated map has revealed the past position of the Australian, Antarctic and Indian tectonic plates, demonstrating how they formed the supercontinent Gondwana 165 million years ago. 'It was a simple technique, matching the geological boundaries on each plate. The geological units formed before the continents broke apart, so we used their position to put this ancient jigsaw puzzle back together again,' said Lloyd White of Royal Holloway University in a press release. 'We found that many existing studies had positioned the plates in the wrong place because the geological units did not align on each plate.'"

    For God, a thousand years are like a day. But a year has 365 days (ignoring leap days for simplicity), so 5000 years have about 9 million days. With every day counting as 1000 years, we arrive at an age of the world of about 9 billion years. This is clearly longer than 165 million years, so everything is fine.

  10. Not only the article is lame. by Anonymous Coward · · Score: 2

    The reconstruction has India moving West away from Australia with the Indo-Pacific archipelago presumably part of Laurasia in a relatively static position as Australia eventually moves northward. Most authors seem to have India moving east upon breakup with Africa and then colliding with southern Asia. Africa presumably splits from South America by moving east relative to South America, so the eastward rather than westward movement of India seems to be correct.

    Obviously, a lot is missing from this reconstruction most notably the position of continental margins peripheral to the map projection. The relative timing of the events from an Australian-Antarctic perspectives seems to be correct but the positioning seems centric to the limited projection used and holding Australia in fixed position is probably the culprit here since positions in the central Indian Ocean are not indicated.

  19. Re:Earth by Anubis+IV · · Score: 2, Insightful

    I'll freely admit that I believe in the unpopular-around-here Genesis account of a literal seven-day creation event, but nowhere in the Bible does it say something along the lines of, "And God created the continents, seven in total. Seven continents did God create, and He saw that they were good." If anything, you could probably make an argument that since the Genesis creation account only mentions one "land", that it may have been meaning a super-continent. Besides which, the Bible makes no claims that would contradict the idea of a super-continent existing prior to the Noahic Flood, and the Noahic Flood would also provide Christians with a reason for why the continents might have split, given that the Bible talks about "the springs of the great deep burst forth" and things of that sort in Genesis 7, indicating that there may have been some significant tectonic events occurring at the time of the flood.

    Long story short, there may be difficulties reconciling the 165 million year age with the Genesis creation account, but there aren't any difficulties in reconciling the idea of a super-continent with the Bible.

    The theory of a 6000-year-old Earth was made by Archbishop Ussher in the 1640s, not in the Middle Ages which ended 400-500 years earlier.

    It was a valid theory at the time, based on the best available evidence, but wrong. Even today there are many theories which are commonly accepted as scientifically valid, but which are most likely wrong in part or entirely. Our descendants will laughingly mock anyone who still believes them, just as some of us dare to mock today.
