The article says Loeb believes he may have found fragments of alien technology. MAY HAVE. He's studying the fragments to learn more about them. I don't see what's so outrageous about that. Loeb is a theoretical physicist who works on astrophysics and cosmology, not some random crackpot. I looked him up; his credentials are beyond impressive. He knows a hell of a lot more about this stuff than I ever will. If he thinks this is a possibility (which is all he's saying, that it's possible), who the hell am I to argue?
But it figures that there are people at DU who think they are smarter than a Harvard professor who has a PhD in plasma physics and a list of other qualifications a mile long. 
Seriously, I dare anyone to look up Avi Loeb in Wikipedia and skim the article on him, then try to tell me this is not a man who is in a position to know what he's talking about. I'll try not to laugh.
