New Theory on “Alien Megastructure”
A new theory has emerged regarding the unusual and intermittent dimming of the mysterious “Tabby” star.
Astronomer Bradley Schaefer from Louisiana State University reviewed 100 years worth of archived photographic glass plates at Harvard University and found that the star had dimmed by about 16 to 20% over the last century.
His findings coincide with the widely held belief among scientists that a large comet disintegrated into thousands of small comets that cross the star regularly, explaining the phenomenon.
