Harvard professor Avi Loeb believes he's found fragments of alien technology

> "We found ten spherules. These are almost perfect spheres, or metallic marbles. When you look at them through a microscope, they look very distinct from the background," explained Loeb, "They have colors of gold, blue, brown, and some of them resemble a miniature of the Earth."

> An analysis of the composition showed that the spherules are made of 84% iron, 8% silicon, 4% magnesium, and 2% titanium, plus trace elements. They are sub-millimeter in size. The crew found 50 of them in total.

Everything in the description could have been produced on Earth using existing technology.

Isotopic composition of the metals could be a very simple way to differentiate the terrestrial from the alien. It's an easy analysis to perform. The fact that it isn't reported at all suggests that Avi Loeb may not have the extraordinary evidence to back up the extraordinary claim.

Searching HN for "Avi Loeb" tells me it's probably confirmation bias.

"Individual who's made a career claiming aliens are among us claims he's found alien artifact"

The "aliens are here" gang are indistinguishable from people who claim to have seen ghosts, bigfoot, loch ness monster, etc.

The human brain is adept at fooling itself.

Reminds me of this youtube vid I saw about him recently, titled "harvard & aliens & crackpots: a disambiguation of Avi Loeb."

"it's never aliens"

Harvard really needs to clean house.

He's not saying it's aliens.. but..

part of the UFO cult
