Whether you know about the Fermi Paradox or
not, it’s pretty strange that no alien civilization has contacted us yet.
According to Enrico Fermi there’s bound to be life in this vast Universe that
is billions of years old with billions of billions stars and planets, some of
which definitely support life in some form. Yet, here we are, all alone. This raises
some questions as to what is the reason we are kept in the dark about other
civilizations. Many theories were created trying to answer the centuries-old question
whether we are alone in the Universe or not. Here are some of the most potent
ones.
We
simply don’t overlap
Compared to the age of the Universe our
human civilization has existed mere seconds if not less. If this is the
lifespan of an intelligent civilization, chances are we simply don’t overlap
with other species as we are set apart in time and space by billions of light
years. We would need to evolve beyond imagination to be able scan large parts
of the Universe and travel through the space continuum in a matter of seconds
so that we could find those alien civilizations. That is before we destroy
ourselves, which is a sad, but probable scenario as of now!
We
don’t meet their standards
We might think of ourselves as evolved
species, but we are no more than monkeys to some of those mighty alien
civilizations from other worlds. In that case they are simply not interested in
contacting us, spending their time observing us, examining, and maybe even
helping us one way or another by means of new technologies and scientific
discoveries. They might have been watching us for centuries!
We’re
living inside the Matrix and aliens are not allowed
It’s a popular scenario stating that we
live inside the simulation created by some higher beings or a really badass AI
in order to harness our energy or whatever other reasons. From this point of
view things that will bring us closer to the truth are simply not allowed
inside the simulation, that’s why aliens aren’t contacting us, despite existing
in some other actual reality we don’t have access to. Of course, information
and images come through, but they are mere glitches in the system and we don’t
have any real evidence proving they exist.
They’ve
contacted us, but the government is hiding it
It’s one of the most popular conspiracies,
which doesn’t get any less potent with time. Things like Area 51 and the
infamous Roswell incident sparked people’s imagination and mistrust towards the
government. It’s easy to imagine that aliens have been in contact with us for
quite some time now, but people holding power decided to keep it a secret not
to cause mass hysteria or for other less noble reasons. Well, you know what?
We’ve been making so many sci-fi movies about aliens that literally no one will
even gasp if a huge spaceship lands in the middle of New York!
It’s
just us
Now this is a scary thought and a highly
improbable scenario according to all the statistics, but it just might be so
that we’re the only intelligent species that made it so far. Well, this time,
if you believe that there were ancient technologically evolved civilizations
long before us. Yet right here right now there’s simply no one to make contact
to! Hopefully, this remains just a theory.
No
one’s reaching out
According to this theory, everyone’s listening,
but no one is giving the signal! Similar like you would sit by the phone (or
messenger) waiting for someone to contact instead of making the first step,
most of the species out there spend their time scanning the space for some
signals, but never emit their own to be found. This happens because of the fear
of hostile civilizations that might be out there waiting for a feeble world to
appear on their radar. This will keep us not only from transmitting our own
signals, but from answering alien’s calls as well! If we’re like that, it’s
easy to imagine that aliens might be just like us. And so we sit and wait for
the call…
They
are trapped on Super-Earths
Here’s good news – there are more planets
similar to Earth than we can count. It’s possible there’s life on these
so-called Super-Earths, but unless we fly there ourselves to check things out,
creatures from these planets will remain hidden. Why? Because Super-Earths are
planets that have a mass at least 10 times greater than that of our planet. This
means it’ll be extremely difficult and expensive to build ships that can
overcome the huge escape velocity and go into space.
We
simply can’t receive their signals
Let’s face it, we aren’t that
technologically advanced when it comes to space stuff. We can barely research
our own galaxy and the radio emissions we’re sending out there don’t actually
reach that far. If we were to travel to Alpha Centauri and then use our current
tech to try and find ourselves – we would fail! We still have a long way to go
in that department. Which means that more developed civilizations might have
sent gazillions of info and messages, but we simply couldn’t apprehend them.
It’s a sad, but very probable theory.
They
are hiding underground
You don’t expect all alien races to look
like humans and live above ground, do you? According to experts, alien life
might very well be trapped in underground oceans, or simply living happily
there and developing at their own pace. Planets with inhospitable surface and
poisonous atmosphere may have oceans that are able to support life in various
forms. This means that just by looking at planets’ surfaces we won’t find any
alien species!
We
should be looking for robots
At the rate our civilization is developing
it’s safe to say that sooner rather than later there will be AIs everywhere. If
they don’t take over us, they will mingle and mix with us, creating new species
of advanced humans. Many scientists and sci-fi writers believe that our future
lies in the machines, that’s why we shouldn’t focus only on finding habitable
world for human-like creatures, but also search for places that would interest
intelligent robots. Like those centres of galaxies that have loads of energy to
feast upon.
We’re
separated by the dark energy
And no, that’s not a cool way of saying that some dark forces are keeping us from seeing other intelligent beings. There’s actually dark energy that’s filling up the Universe, an invisible substance that is stretching it, pulling us further from potential alien friends and foes. Scientists speculate that in some trillion years the Universe will expand so much that we won’t be able to see the Galaxies that are shining brightly to us right now. That will make encountering an alien civilization nearly impossible!
