Don't worry, its not a spaceship -- maybe

[ashling]

Interstellar object 'Oumuamua - that strange, cigar-shaped chunk of rock from somewhere a vast distance beyond the Solar System - is, new research has concluded, absolutely, positively not an alien spaceship.

OK, well, probably not. We can't tell for sure without closely examining the thing, and it's passed beyond our reach now. But, after carefully reviewing all our observations of the object, the international team of 'Oumuamua scientists has concluded that everything we know about it is consistent with a natural origin.

2. It could be a piece of a spaceship

Oumuamua could be defunct sails floating under the influence of gravity and stellar radiation. Similar to debris from ship wrecks floating in the ocean.

6. There is not stellar radiation in interstellar space.

So it would likely have another propulsion force driving it. It could be a remnant from the formation of the Milky Way Galaxy that is simply obeying galaxial orbiting dynamics, that would make some sense given that it's speed was well beyond everything within the solar system, except the Sun as it moves around the galaxial core.

5. Erich von Dniken's new book "Turds of the Gods" solves the mystery.
