http://goo.gl/AWppk0 Is it possible we've finally picked something up from extraterrestrial life? I know there was an MIT professor, Seth Lloyd, back in 2013 who said that aliens could be dark matter. "But, Lloyd also notes that the overwhelming majority (85%) of our universe is made of dark matter, a substance that scientist still do not understand. In contrast, regular matter only accounts for 4.9% of the universe. Therefore, Lloyd proposes that "the aliens are the cold dark matter that makes up 23 percent of the energy in the universe. Adept at cloaking themselves, they are invisible under any force that can be shielded."
