Invisible Aliens – Extraterrestrial Life May Be Beyond Human Understanding – MessageToEagle.com.
Are alien civilizations invisible to our technology?
Do aliens exist in forms we cannot conceive, as several scientists
pointed out? Have we been looking in the wrong place, at the wrong time,
in the wrong way?, asked Dr. Paul Davies from Arizona State University.
Xenology is a most fascinating subject as it deals with all aspects
of extraterrestrial life. We would all like to know what they look like,
what they think, how they behave, and so on. However, in order to
answer those questions we must first find those extraterrestrial
As the quest for extraterrestrial life continues, scientists keep
debating what methods should be used. According to Dr. Paul Davies, the
approach currently being undertaken by SETI researchers is too narrow,
assuming aliens communicate the same way we do here on Earth.
There are an estimated 250 billion (2.5 x 1011) stars in the Milky
Way alone, and over 70 sextillion (7 x 1022) in the visible universe,
and many of them are surrounded by multiple planets. The shear size of
the known universe is staggeringly and inconceivably vast.
The odds of there being only one single planet that evolved life
among all that unfathomable vastness seems so incredible, that it is all
but completely irrational to believe. But then “where are they?” asked
physicist Enrico Fermi while having lunch with his colleagues in 1950.
Fermi questioned, if there are other advanced extraterrestrial
civilizations, then why is there no evidence of such, like spacecraft or
probes floating around the Milky Way. His question became famously
known as the Fermi Paradox.
paradox is the contradiction between the high estimates of the
probability of the existence of extraterrestrial civilizations and yet
the lack of evidence for, or contact with, any such civilizations.
Given the extreme age of the universe, and its vast number of stars,
if planets like Earth are at all typical, then there should be many
advanced extraterrestrial civilizations out there, and at least a few in
our own Milky Way.
closely related question is the Great Silence, which poses the question:
Even if space travel is too difficult, if life is out there, why don’t
we at least detect some sign of civilization like radio transmissions?
Milan Cirkovic of the Astronomical Observatory in Belgrade, points
out that the median age of terrestrial planets in the Milky Way is about
1.8 gigayears (one billion years) greater than the age of the Earth and
the Solar System, which means that the median age of technological
civilizations should be greater than the age of human civilization by
the same amount.
The vastness of this interval indicates that one or more processes must suppress observability of extraterrestrial communities.
Alien planet can be very different from our Earth.
Since at this point, there is no direct and/or widely apparent evidence
that extraterrestrial life exists, it likely means one of the following:
We are (A) the first intelligent beings ever to become capable of
making our presence known, and leaving our planet. At this point, there
are no other life forms out there as advanced as us. Or perhaps
extraterrestrial life does exists, but for some reason extraterrestrial
life is so very rare and so very far away we’ll never make contact
anyway-making extraterrestrial life nonexistent in a practical sense at
Or is it (B) that many advanced civilizations have existed before us,
but without exception, they have for some unknown reason, existed
and/or expanded in such a way that they are completely undetectable by
Or is it (C) There have been others, but they have all run into some
sort of “cosmic roadblock” that eventually destroys them, or at least
prevents their expansion beyond a small area.
One reason why might not be able to detect aliens is because they are
invisible to our technology. We are looking for something that
resembles us, but extraterrestrial life can be beyond human
So, what do they really look like?
“They could be staring us in the face and we just don’t recognise them.
The problem is that we’re looking for something very much like us,
assuming that they at least have something like the same mathematics and
technology,” said Lord Martin Rees, president of the Royal Society and
astronomer to the Queen.
“I suspect there could be life and intelligence out there in forms we
can’t conceive. Just as a chimpanzee can’t understand quantum theory,
it could be there as aspects of reality that are beyond the capacity of
They could very well be just around the corner, but we cannot see
them because they are simply not life as we know it, at least not yet.
Maybe we don’t really know what to look for yet and that is why they are
invisible to us…
