Oumuamua: an ancient alien solar sail sat? (video).

In this 40-minute-long video, we examine how iIn late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system.

Harvard astronomer Avi Loeb concluded that the object (which became known as ‘Oumuamua) was not an asteroid or comet; it was moving too fast along a strange orbit, and left no trail of gas or debris.

He shared his controversial theory that the object was a piece of advanced technology created by a distant alien civilization, and the profound implications of this.

The object had no trace of carbon-based molecules or dust around it, and because of the way sunlight reflected off it, Loeb determined that it was pancake or disc-shaped rather than the cigar shape that was popularly depicted.
