Scientists have said that the infamous ‘alien megastructure‘ on the star named KIC 8462852 still hasn’t yet been explained, despite efforts by a University to ‘dispel’ the alien theory. Researchers say that their original idea that the strange dimming of the star was as a result of a giant alien megastructure harnessing its power, is still as valid today as it was weeks ago. A debunking theory by Massimo Marengo of Iowa State University claimed that the dimming was caused by a huge body of comets passing directly in front of the star, has itself been debunked by scientists. Huffingtonpost.co.uk reports: Well now even that theory has been seemingly disproven by Dr. Bradley E. Schaefer, a professor of astronomy and astrophysics at Louisiana State University. Dr Schaefer claims that the comet theory just doesn’t hold up, arguing that for comets to be the reason there would need to be at least 648,000 giant comets (all with a diameter of 200km) and for all of them to pass in front of the star in the space of just a century. Now as you can probably guess, that’s highly unlikely. The only problem is Schaefer doesn’t yet have an alternative, so while we can [...]
