Writer James
Mellor said in his report, which was published in the French newspaper, Le
Point, that the discovery of phosphine on Venus suggests that several
hypotheses will emerge.
Reaching out
signs of life on Venus might be a very bad thing for the future of humanity,
and according to one theory, if we have not seen aliens yet; It is because it
tends to destroy itself before it has time to invade galaxies.
Billions of
planets
This hypothesis
was made by the Italian-American Enrico Fermi (1901-1954), in the context of
the Fermi paradox, and in the context of the question of the reason for the
unity of Humans in this vast universe.
It is estimated that our
galaxy alone is home to about 20 billion Earth-like planets, many of
which may be more than a billion years old.
It is easy to believe
that another civilization outside the planet is able to come to Earth, given
the speed of light. So why is there not at least one planet in our galaxy that
has spawned an intergalactic civilization that we can discover?
On planet Earth,
for example, life is distributed from the depths of the oceans to the highest
mountain peaks. So why hasn't this happened elsewhere in our galaxy as well? We
can expect that strange types of creatures want to colonize all areas of the
universe that they have access to, just as humans used to occupy all habitable
areas on Earth.
And in about a
thousand years, if the pace of technological change continues, there is no
doubt that humankind will send spaceships to colonize other star systems.
In return, these
new worlds will send their ships to other planets. In a million years, which is
equivalent to the blink of an eye on the scale of galactic existence, we might
be able to reach all the stellar systems in our galaxy; But why did other
creatures not come to occupy us today?
Life .. not
civilization
If we want to be optimistic,
we will consider that we have not seen aliens until the end of the day.
Because it does not exist, and the emptiness of the universe hinders humanity
from moving into trillions of uninhabited planets.
But the
information recently discovered about Venus raises doubt, as the acid
atmosphere of Venus bears traces of a rare molecule, phosphine, which is found
on Earth and associated with microbes that live in environments devoid of
oxygen.
No researcher
can claim to have discovered real life, and even if these microbes were present
on Venus, many factors could explain why the development of life on Venus
stopped long before intelligent life forms developed.
The writer says
that this does not mean at all that a civilization developed and was
annihilated on Venus. But if microbes are found on Venus, it will help show
that spontaneous generation, which means the evolution of life forms, is not a
phenomenon specific to our planet.
Self-destructing
intelligence
Let's imagine
that we know that thousands of advanced civilizations have already appeared in
our galaxy long ago. All of these civilizations may have eventually succumbed
to internal conflict, destroying each other with nuclear weapons before they
had a chance to spread to another star system.
And if we
actually find life on Venus, it might have the same origin as life on our
planet, it is possible that primitive life appeared only once in our solar
system, and perhaps once in the entire visible universe, on Earth or Venus,
before it moved to planet else.
Or maybe life
started elsewhere and somehow made its way to our solar system aboard a comet,
or perhaps one of the spaceships that we sent out into space accidentally
infected Venus with our microbes. In all these scenarios, life on both planets
will have a common bond.
A lethal
technological move
Beyond the
self-destruction of civilization by wars or disasters such as asteroid impacts,
advanced societies have another cause of mass destruction: a trap masked by the
laws of physics similar to the first atomic bomb. All civilizations will become
extinct in the same way, by taking a lethal technological step, according to
the writer.
The writer
emphasizes that many of the theories of the great candidate (self-destruction)
that have been proposed are unrealistic, and he says that bacteria are
self-reproducing. And some terrestrial probe bacteria could have a truly massive
impact on Venus if we assume that they could have found food in the atmosphere.
By analogy, humans could someday create intelligent robots capable of traveling in space, and using materials from other star systems to create billions of copies of themselves, such as bacteria, these new robots could then begin to reshape planets to make them liveable.
