Digging through scientific papers as I do to research the
content featured on this channel is something very much like hunting for Easter
eggs. I would never call any scientific work mundane, any work done by
scientists helps to advance our understanding of our world around us, but I
might say that most subjects one sees in scientific papers just would not make
for good YouTube videos unless done by a creator far better than I.
But several times a week I find papers, or easter eggs if
you will, that excite me and then I go make videos on them. Occasionally,
however, I will read a paper that absolutely blows my mind. That definitely
happened this morning.
This paper is entitled "Prior Indigenous Technological Species"
and was authored by Dr. Jason T. Wright of the Department of Astronomy and
Astrophysics and Center for Exoplanets and Habitable Worlds at Pennsylvania
State University ,
link to the paper in the description below. It's a good read folks.
But first some back story. It might surprise you, but it is
fully scientific to consider the possibility of alien life having visited our
solar system in the past. Carl Sagan and I.F. Schklovskii pointed this out in
their book "Intelligent Life in the Universe" in 1966. This is
independent of the question of whether the human race has ever interacted with
an alien race. I have no problems with those that have concluded otherwise, but
I have personally seen no compelling evidence that would lead me to conclude
that we have. I have only seen material that leads me to more questions.
But the universe is a very old place, certainly old enough
for other technological civilizations to have arisen long before ours did. It's
also sufficiently old enough for an ancient civilization to have explored the
galaxy end to end without exceeding the speed of light. Earth too, is
sufficiently old enough to have been explored at some point in the distant
past.
And, it's also fully within the realm of solid science to
look for evidence of that as part of SETI operations, and indeed I've made several
videos on this channel on the possibility of Bracewell or von Neumann probes
hidden somewhere in the solar system. The tough question though is how likely is
it that such a thing might exist?
This subject was tackled in a 2011 paper by Jacob Haqq-Misra
and Ravi Kumar Kopparapu entitled "On the Likelihood of Non-Terrestrial
Artifacts in the Solar System", link to the paper in the description
below. They concluded that we simply have not explored our solar system thoroughly
enough yet to detect such probes, if they exist, and that we should probably
keep our eyes open for them just in case.
Dr. Wright in his new paper takes an interesting approach to
the question of artifacts of other civilizations present in our solar system.
He points out that while astrobiologists focus on searching for present or past
evidence of simple life in our solar system, it may well be the case that
artifacts of advanced civilizations are easier to find. And, going further, he
suggests that the origin of such an artifact does not necessarily need to be
another star system, but could be the solar system itself.
It is possible that advanced civilizations may have
developed in the past on Earth, or even Mars or Venus which are thought to have
once been earth-like. But Earth and Venus are geologically active worlds that
renew their surfaces, so any evidence of an ancient civilizations is likely to
be long gone on these planets. But you might find evidence of them on less
active worlds like Mars or the Moon. Another possibility is that we might find
an asteroid that was clearly mined at some point, perhaps by a von Neumann
probe passing through.
Dr. Wright points out though that if we do find evidence, which
we currently have absolutely none that stands up to scrutiny, then you must
consider that the origin might not be another star system, but instead may be
more likely to have originated from our own star system, especially considering
that Earth would be a sort of elephant in the room since life has clearly
arisen here.
While I consider it unlikely that there were ever precursor
civilizations in our solar system, it is possible. And it's also possible that
some day in the distant future others, perhaps from some formerly frozen moon
made habitable by the brightening sun, might find evidence of us.
