Sam Posted December 29, 2010 Share Posted December 29, 2010 This is a conspiracy theory that's been going around for a while. We were all supposed to be wiped out by the same thing in 2003, I'm quite sure that didn't happen by virtue of the fact we are all still here. The story re-surfaced and has since been linked to the end of the Mayan calendar. There's some pretty ridiculous stories whizzing around about the so called Planet X such as it's approcahing Earth and governments are hiding it from us. Not likely as someone on SGL would have imaged it by now plus something as visible as some claim it to be would be very hard for governments to hide. There seems to be an awful lot of psuedoscience surrounding this and seems to me to portray the whole thing as rubbish. Link to comment Share on other sites More sharing options...
ollypenrice Posted December 29, 2010 Share Posted December 29, 2010 Thanks for the clarification! I think these absurd plot theories may be invented by goverrnments to discredit those prescient theories that have successfully exposed their real plots...(Hey, my first plot theory! Let's see if it takes wing...)What is rather sad, though, is that idle-minded souls, too incurious to read a word within the scientific culture on which they depend, should be so full of energy when it comes to propagating pseudo scientific drivel.As for the Mayan long count, probably the most accurate calendrical system ever devised, remember that they were writing on limestone using obsidian tools. The probably just got fed up with all that chipping and stopped when they did...Olly Link to comment Share on other sites More sharing options...

E621Keith Posted December 30, 2010 Share Posted December 30, 2010 Planet X? I think it's called Mondas, home planet of the Cyberman . They also make very expensive carbon racing bikes.Anyway, it's very unlikely they will find the ninth planet, let alone 10th. I'm sure more and more dwarf planets will turn up, but I doubt anything new will fit IAU's new definition of planet. Link to comment Share on other sites More sharing options...
Hypernova Posted December 30, 2010 Share Posted December 30, 2010 We will have to wait for the results from NASA's "WISE" mission, which is currently undertaking an all sky survey in infrared wavelengths to search for nearby cool brown dwarfs and distant planets, to be sure if there is another planet in the solar system or not. It has already discovered tens of thousands of previously unknown asteroids and a couple of comets as as well as a few brown dwarf candidates.Wide-field Infrared Survey Explorer - Wikipedia, the free encyclopedia Link to comment Share on other sites More sharing options...

acey Posted December 30, 2010 Share Posted December 30, 2010 Other than Pluto, "Planet X" often refers now to "Niburu", a supposed planet in the pseudo-scientific ideas of Zecharia Sitchin, which is connected with Mayan 2012 pseudoscience. Not taken seriously by any sane astronomers.Zecharia Sitchin - Wikipedia, the free encyclopediaNibiru collision - Wikipedia, the free encyclopediaPlanet X (disambiguation) - Wikipedia, the free encyclopedia Link to comment Share on other sites More sharing options...
umadog Posted December 30, 2010 Share Posted December 30, 2010 I've just finished reading "How I Killed Pluto and Why it Had it Coming". Good read. The author mentions that no serious astronomer any longer believes in Planet X. Note that "Planet X" does not simply mean "unknown planet"; there was a more precise definition. Lowell proposed the existence of a "Planet X" to explain apparent discrepancies in the orbits of Uranus and Neptune. By the mid 20th Century it was demonstrated that Pluto is too small to explain such discrepancies and so cannot be Lowell's "Planet X". Even at the time of discovery, its size did appear to be smaller then predicted. Link to comment Share on other sites More sharing options...
Skybrowser Posted December 30, 2010 Share Posted December 30, 2010 Have a look on You Tube as well - loads of Niburu guff there too. The conspiracy theorists are probably the same lot who go on about Area 51 and that the moon landings were done in a studio. Oh and Kennedy was murdered by government people too. What these nutters fail to realise is that some people will actually believe this nonsense and some will be genuinely concerned, even scared by it.Planet X seems like it's something straight out of a 1940s Flash Gordon movie. Either that or the Green Mekon lives there (yes, I remember the Eagle comic).It is all a load of tosh, including the Mayan stuff. Brian Cox summed it up in his own inimitable style on Twitter a few months back, using words which would get me banned from SGL if I repeated them here.There are hundreds of thousands, if not millions of astronomers in the world and by now, one of us would have spotted it, imaged it and asked for feedback as to whether we've been a bit on the heavy side with the colour curves in Photoshop!

iamjulian Posted December 30, 2010 Share Posted December 30, 2010 Umadog, I added that Pluto book to my Amazon wish list today. Read Mike Browns stuff in "Hunt for Planet X" which was a great book (about discovery of Pluto and Kuiper Belt objects, not this wacky Niburu thing). Currently reading "Pluto: Sentinel of the outer solar system" which is also a good book. I read Richard Muller's book and asked him just last year whether he still believed in his Nemesis "planet" and he said yes. Link to comment Share on other sites More sharing options...

SiriusB Posted January 2, 2011 Share Posted January 2, 2011 By the mid 20th Century it was demonstrated that Pluto is too small to explain such discrepancies and so cannot be Lowell's "Planet X". Even at the time of discovery, its size did appear to be smaller then predicted.I read that somewhere too- So how do they explain these perturbations? Maybe there is indeed a planet "X" making Uranus & Neptune misbehave?If so, i find it a little hard to believe its going to suddenly leap out of its orbit & make a beeline for planet earth.Something may hit us one day, but not, i suspect,, planet "X" even if it does exist.

acey Posted January 2, 2011 Share Posted January 2, 2011 The perturbations were found to be non-existent once more orbital data was acquired (Uranus and Neptune have very long orbital periods). It just so happened that Pluto was in the region of sky where the supposed Planet X was expected to be. Link to comment Share on other sites More sharing options...
