EXTRATERRESTRIAL

Have we been visited by aliens?

Harvard astronomer Loeb believes we have, basing his assertion on “evidence…collected over eleven days, starting on October 19, 2017,” at a Hawaiian observatory. That’s when the author, the director of the Black Hole Initiative and the Institute for Theory and Computation, and his fellow scientists unexpectedly observed the “first known interstellar visitor.” It was a small object: “highly luminous, oddly tumbling, with a 91 percent probability of being disk-shaped.” Moving roughly 58,900 miles per second, it “passed through our solar system and, without visible outgassing, smoothly accelerated from a path that deviated from the force of the sun’s gravity alone.” Loeb and his colleagues named it “Oumuamua,” a Hawaiian word that roughly translates to scout. Though the scientific debate continues, writes the author, “the likelihood of scientists ever observing demonstrable proof is very remote.” Loeb meticulously analyzes the evidence they have so far: No “confirmed interstellar object had ever been observed in our solar system,” and it wasn’t a comet or asteroid. Further research revealed that it rotated every eight hours and was approximately 100 yards long and less than 10 yards wide. Its unique, “smooth and steady” acceleration and deviation from the sun led the author to a hypothesis that charmed the media but generated “intense controversy and pushback” from other scientists. Loeb also delves into the object’s spin rate, unchanging rotation, and the possibility that it might be another civilization’s space hardware. After all, we’ve been “junking-up” space for years. Loeb issues a clarion call for a team of astro-archaeologists to increase research into possible alien life; unfortunately, the “conservative scientific community” has always fought against such research. It’s hard to argue with the author’s claim that it’s the “height of arrogance to contend that we are unique,” and he even speculates that life on Earth may be of Martian or interstellar origin.

A tantalizing, probing inquiry into the possibilities of alien life.
