Sure, this isn’t
science fiction but it certainly is close. After all, in science fiction we
deal with intelligent life on other planets and alien visitation to Earth, or rather
our Solar System. Now, it seems that that visitation has happened.
Harvard scientist, Dr. Abraham
(Avi) Loeb, who is the chair of the Department of Astronomy, has suggested that
we were visited in 2017. Well, visited isn’t quite the right word but that an
alien artifact had entered the Solar System.
Dr. Avi Loeb
In my communications
with Dr. Loeb, I asked a number of questions, such as where it might have
originated. According to the data, it came from the direction of Vega, which is
about 25 light years from Earth.
On September 6, 2017, the
artifact crossed into the orbital plane of the Solar System, and on September
9, it made its closest approach to the sun. On October 7, it passed Earth,
moving in the direction of Pegasus. Or, in other words, flew by and is on its
way somewhere else.
Earth-based scientists
were able to study the object, which was about three hundred feet in length,
and had a somewhat cigar shape and was rotating slowly.
It was named, “Oumuamua” which means scout in Hawaiian.
It was, at first believed to be a comet, but it exhibited
none of the characteristics of a comet. That suggested to Dr. Loeb that it was
something completely different.
Dr. Loeb told Isaac Chotiner of The New Yorker, “There is a Scientific American article I wrote where I summarized six strange facts about
‘Oumuamua. The first one is that we didn’t expect this object to exist in the
first place. We see the solar system and we can calculate at what rate it
ejected rocks during its history. And if we assume all planetary systems around
other stars are doing the same thing, we can figure out what the population of
interstellar objects should be. That calculation results in a lot of
possibilities, but the range is much less than needed to explain the discovery
of ‘Oumuamua’.”
He also suggested that the civilization that sent out the object might
no longer exist. I had wondered about the speed reported as it passed through
the Solar System, suggesting a very long flight time to get here. Some the
commentators to my A Different Perspective blog suggested that it had
slowed as it passed by or that it had arrived via a wormhole. I sort of ignore
that without evidence to the contrary but do acknowledge the possibilities.
Nearly all the scientists agree that the object did not
originate in the Solar System, which makes it the first alien object to be
observed in the solar system. While Dr. Loeb believes that it is an artificial
object, many scientists disagree.
In an article published in July 2019, it
was concluded, “We find no compelling evidence to favor an alien explanation
for ‘Oumuamua’.”
I, on the other hand, am rooting for Dr. Loeb’s
explanation but must note that while the object is certainly alien, it is not
necessarily artificial which takes some of the fun out of this.
