Hi, I’m new to the forum, having joined after 6 pints on Saturday night while looking for historical evidence of the mythical 10th planet as described by the ancient Sumerians. The purpose of this post is to spark debate, hopefully backed up with facts that can be verified (and I don’t really mean you tube videos or other web sites who’s contents are rehashing of various theories often with no basis in fact or science, a good example of this is a site called badastronomy.com, if anyone quotes this site as fact, there is a chance I’ll hunt you down and attach large crocodile clips to your gonads wired into the mains supply, just for being so stupid.). To start with, let me state my position. I’m prepared to accept the possibility of another large body in our solar system, even one that is on a highly inclined orbit that has not been found by our current science. Indeed, as I understand it, within astronomy circles this idea may itself be gaining some acceptance as there are some anomalies in the orbits of the outer planets that could be explained by the movements of such a body. Please note that I’m using words here like ‘may’ or ‘could’ because I’m not completely sold on the idea, I’m just prepared to explore it. From what I have read on the subject, the mysterious planet apparently has a orbit in the region of 3600 years, and this causes a few issues for me as the Sumerian tablets that reference this body are were penned (made) around the early part of the Sumerian civilisation approximately, and its a very rough approximation, of 4000 bce or so. If that is the case, then surely it should have made another pass at around the time of Alexander the Great who was undeniably a man who liked to have things written down, especially about himself. In all the contemporary Greek works I have located about that time, very few, in fact none, mention a large red star that caused a lot of devastation, earthquakes, floods ect. There are a lot of references to Alexander himself stabbing anything in his way to death (best friends, enemies, it didn’t really seem to matter a lot to him what side you were on) as he rampaged through the then known world. Looking comparatively at other ancient texts, there are not many that cover the same time period where evidence can be found. The Rig Vadas (Sanskrit texts) do appear to go back that far, but they don’t mention the planet either. I have read most of them now, and have not been able to locate anything that can be considered as evidence for this mysterious planet (please note though that the 4 ages or Yuga that are talked of often in these texts are 7200 years in length, exactly 2x3600, I’m not saying that has any relevance but it is odd they would arrive at a figure that could at a stretch be somehow linked). Nor is there anything in any of the ancient Greek texts either prior to Alexander, even when they talk of their golden age when Gods and Titans roamed all over sleeping with anything that moved, animal, mineral or vegetable. As a general side note, please do go read the Rig Vadas, nothing about mysterious planets, but a shed load of other stuff that really is mysterious. The only other place I have found anything that can be referenced as an unexplained solar body is in translations of Mayan mythology (with the exception perhaps of the star of Bethlehem story and I’m not going anywhere near that), and its from these guys that the name ‘Nibiru’ seems to come from. They are also the ones responsible for the current 2012 hysteria gripping the internet, but reading a little deeper and cross referencing with some current astronomical studies its entirely possible they were really talking about the upcoming transition through the galactic equator supposedly happening between now and 2015 by modern calculations. Either way, I have a basic unwritten rule in life not to take anything seriously from anyone who thought it was a good idea to rip the beating hearts out of other people, and the Maya did a lot of that so I tend to take what they say with a hefty dose of salt. It is worth mentioning though that the Maya were around from approximately 1800 bce’ish to 500 or so ce, so some of the stuff they wrote about (or drew glyphs about) was in the right time period to record the passing of the planet if it does indeed exist. So without much written evidence (and what there is can be subject to interpretation) where else can evidence be found? Is there any geological evidence to support the idea that there is a 3600 year cycle of general mayhem and destruction? Is there any ice core evidence to support the idea that on or around that 3600 year period there is increased volcanic activity? Is there any physical evidence (tree ring studies, increased or decreased glaciation, anything!) at all to support the idea that this cycle could be real? If anyone knows of any such evidence, please post up about it and where it can be found? I would welcome serious informed debate on the subject. Before I sign off, a little about myself for anyone who is interested, or anyone currently studying radio theory, electromagnetics, or nuclear theory. I spent over a decade in the Royal Navy as a radio/RADAR engineer and was involved with submarine pressurised water reactors for 2 years or so. I think I have a fairly well grounded, practical understanding of the subjects and could probably aid in explaining some of the theoretical or practical elements if anyone is writing collage papers etc, feel free to ask, if I don’t know I’ll say so pretty quick. Utwig.
