Theoretical astrophysicist and Harvard professor Avi Loeb has a message for scientists who are skeptical of the existence of extraterrestrial life: Seek out the truth. Loeb recently led an expedition to study the crash site of an interstellar meteor that he believes could provide answers. "Many of the scientists pretend to be a scientist, but they are not really seeking the evidence, and they push back with very strong opinions that are not supported by anything," Loeb said on "Elizabeth Vargas Reports." #AviLoeb #UFO #science More #VargasReports: newsnationnow.com/joinus Anchor Elizabeth Vargas delivers the biggest stories, without bias or opinion.
