Below is a link from my facebook feed. Sure there is lots of crap in my feed and most of the ads are misleading BS. This one sounded familiar and you know me, I try not to be swayed by my cognitive biases - and this one hit the 'mere-exposure effect'. January 4th, 2015 at 9:47am PST the entire Earth will be weightless for 5 minutes. Wait - because of Pluto? Yep - the article claims that little no-longer-a-planet, Pluto will be the cause. Of course a quick BS-Check on Google, Bing, Snopes will tell you that this hoax has been around since the 70s. According to Snopes it was 1976, "took place in 1976, when British astronomer Patrick Moore informed a radio audience that the movement of two planets would result in an upward gravitational pull which would make people on Earth lighter at precisely 9:47 a.m. that day."
What I find interesting is that Buzz Live's page on this has over 616,000 shares on Facebook and 23,521 ReTweets without mentioning that it is untrue. Somewhere on the page should be just a little mention that this is a joke.
