Could mysterious 'alien spacecraft' be nothing more than cosmic dust?

Abraham Loeb, Harvard's top scientist, raked up controversy recently after he stated that at least one alien spacecraft exists among us.

The research, written by Zdenek Sekanina and put online here, theorizes that Oumuamua could be nothing more than "a monstrous fluffy dust aggregate" made up of a broken up comet.

The new paper adds another loop to the already-knotty issue by suggesting that the object changed during its brief time in our solar system. This was the first interstellar object astronomers ever spotted, though there may have been thousands which had gone unnoticed. So, while the object appeared reddish, long and thin during its exit, it may have started out with different properties. Typically, when these faint comets come within a quarter of Earth's distance from the sun, they don't survive the visit. The new paper proposes that a similar fate to C/2017's befell Oumuamua, with its outburst coming before any scientific observations occurred, thus disguising the object's original structure.

The paper proposed that 'Oumuamua may have been the result of a comet's death - a clump of remnants instead of the solid body scientists thought it to be when they first spotted it.

In an interview with Chicago Tribune, Avi Loeb, head of Harvard University's astronomy department, shared that he has been working on an equation that will prove that the unusual interstellar object, called Oumuamua and now passing the orbit of the Jupiter, is a part of an alien spaceship.

Loeb said to TheDCNF that Harvard has been "very supportive" despite the push back from others, with the university even publishing an article on the professor's theory. 'If someone shows me evidence to the contrary, I will immediately back down.' That lack of evidence is part of the problem with much of the research efforts focused on Oumuamua.

"Considering an artificial origin, one possibility is that 'Oumuamua" - pronounced Oh-mooah-mooah - "is a lightsail, floating in interstellar space as a debris from an advanced technological equipment", Loeb wrote with his colleague Shmuel Bialy in Astrophysical Journal Letters in November - thrilling E.T. enthusiasts and upsetting the fragile orbits of space academia.
