He said it might belong to aliens: The situation is a bit more complicated

Harvard astrophysicist Avi Loeb believes he may have discovered fragments of alien technology from a meteor that crashed off the coast of Papua New Guinea in 2014.

As reported by Chip, while searching for the meteor known as IM1, Avi Loeb announced that his team had found 10 small spheres made mostly of iron. Loeb said, "When you look at them under a microscope, they look very different from the background. They have gold, blue, and brown colors, and some of them resemble a miniature of the Earth. The fact that they are made of materials even harder than iron meteorites suggests that they could be a spacecraft or some technological device from another civilization."

CLAIMS WERE CHALLENGED; THEY MIGHT BE MAN-MADE

Many scientists opposed Loeb's claims, saying he was acting prematurely. Now, a scientist says these metal spheres could simply be industrial waste. According to the analysis, the mysterious spheres could be a result of burning coal.

Patricio Gallardo, a research associate at the University of Chicago, analyzed the chemical composition of coal ash, a waste product left behind by burning coal in power plants and steam engines. Gallardo says the results are consistent with the concentrations of iron, nickel, beryllium, lanthanum, and uranium reported by Loeb and his colleagues in the metal spheres. "A meteoritic origin is unlikely," Gallardo wrote. Gallardo's analysis was published in a non-peer-reviewed journal.

Loeb, however, opposed the theory, arguing that it was "based on unverified interpretations that superficially examine a few of the dozens of elements they analyzed."

In a paper published in August that has not yet undergone peer review, Loeb and his team say that 5 of the 57 spheres analyzed are indeed strange. The paper argues that their findings "support the interstellar origin" of these spheres. Loeb and his colleagues, who named these five spheres BeLaU, argued that they "could reflect an extraterrestrial technological origin," but stated that the claim requires further investigation.
