3 Possibilities Why We Haven't Seen Any Aliens
The universe is so vast and infinite that it is impossible to know about all of it. It's full of
beautiful places and never ceases to amaze us. But beside this beauty there can be something scary
also out there or maybe not. Arthur Clarke said, “We are either alone in this universe or we are
not, and both these thoughts are equally scary.” Can it be that we are alone in this Universe? Or
if we aren’t, where are all the aliens? Our universe is so vast, but still we have found
no trace of life on another planet or even traces of microbial life! In this universe we have a lot
of galaxies very similar to the milky way, and they might have a solar system similar to ours.
And some of these stars might have planets like our Earth, just like Kepler-432b, which is very
similar to Earth and even has water. On February 22, 2017 NASA announced the discovery of the most
Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of
seven rocky worlds–all of them with the potential for water on their surface–is an exciting
discovery in the search for life on other worlds. There is the possibility that future study of this
unique planetary system could reveal conditions suitable for life. But why haven't we seen
any aliens yet? Will we be able to make contact with them? Or are we just alone in this universe?
Some places in the universe might have intelligent life because the universe is
very old and many stars and planets have been formed before humans came into existence.
If any civilization existed in this old universe, they might have had a lot of time to advance
themselves. Our Milky Way is about 13 Billion years old. Initially it was not suitable for
habitation but after 2- 3 billion years conditions were hospitable for civilisations to exist.
Our planet is about 4.54 Billion years old and many civilisations could have existed before us.
Bad on the Kardashev scale, civilisations are of three types.
A type one civilisation is the one that has used all the resources of its planet. We are currently
0.75 on this scale. A type two civilisation is the one that has used all the energy of its host star,
like the concept of Dyson Sphere. A type three civilisation is the one that has colonised and
used all the natural resources of its galaxy and will be God like to us. So if that’s the case,
and leaving out the probability that we are not alone, because that would mean we are special,
where are all The ALIENS? Why haven’t we met or seen any trace of aliens?
Where is everybody? Welcome to the Fermi paradox. No one has answers to this. All we have are
theories, and in these videos we are going to share with you some of these possible answers to
the fermi paradox. Let’s discuss some of them. Search for extraterrestrial life or SETI is an
organisation dedicated to finding evidence of life in other places of our universe.
But SETI has always been under-funded and looked down upon by the world. Earlier it was established
like an organisation like NASA until Congress cut down its findings and now it mainly relies
on donations. Another organisation, METI is a fairly new project which is known as Messaging
extraterrestrial intelligence. Its main objective is to send messages to extraterrestrial beings and
try to make contact with them. It creates and transmits interstellar messages in order
to attempt communication with extraterrestrial civilisations. METI targets nearby star systems
and also rethinks the nature of the messages to send. Although The scientists at SETI and METI
have had little resources to observe outer space, and that’s true. In our Milky Way,
which is very vast, SETI has only observed about a fraction of the entire galaxy.
So we have observed little of the universe and our galaxy. It's just like going to a beach and
taking water in your beaker and saying that there are no sharks in the ocean because there are no
sharks in my beaker! We have sampled little of the universe. We all know life has occurred in extreme
and harsh environments which is evident from life on Earth and can evolve under those conditions.
The universe is vast enough with trillions and trillions of planets.
So it is possible that life could occur anywhere, it is just that we haven’t observed it.
Another idea is that there is a Godlike and very advanced type 3 civilization out there
that monitors the galaxy and once any civilization reaches a certain level of intelligence,
it destroys it. It is possible that they might have passed all kinds of hindrances that occur
for life to exist and now are at a very advanced state of intelligence. It could be that they might
have gotten bored and created us to observe us in their leisure time. To prevent competition in the
future when we start to advance ourselves into a higher civilization they might contact us and kill
us. We could be just like viruses that start and spread. We might be in a tightly regulated galaxy,
and they treat our Earth like part of a vast and protected national park. We know this as
the ‘Zoo Hypothesis’. It might be that they are just watching us like we watch animals in a zoo?
The zoo part has a certain significance to it. Today the animal zoos have to keep animals caged
so that we can observe them and more importantly go on a summer evening and just
watch them with some snacks. What if we are the same animals for a god-like alien civilization?
The thought itself is terrifying for a lot of people. So if we were living in a galactic zoo
it would be pretty much quiet. It would be something like going out and observing animals
in a zoo. Just like in a zoo we observe zebras and then move on to the other animal. The animals
talk or communicate among themselves and we just see and enjoy them doing their own animal stuff.
The aliens in the same way might be observing us doing our weird human things that we do. But
what if we could tweak this scenario a little bit to actually establish interspecies communication.
That's the main purpose of SETI and a new project called METI (Messaging extraterrestrial
intelligence), where they actively send messages of their own trying to make contact. The other
question would be who are the zookeepers? This idea and thought itself is scary.
We have seen and read a lot of sci-fi movies and novels which show that we live in a simulation
or we are some kind of experiment not knowingly and there is someone watching and observing us.
Another idea is that there might be scary predator civilisations out there and are smart enough to
not broadcast their location and remain discreet. This would mean that we are fools in fact and
cannot see them because they don’t want us to. This also explains why we have found no signals
in SETI. Because as Stephen Hawking said, if they visit us, the outcome would be the same as when
Columbus landed in America, which didn’t turn out well for the Native Americans.” It’s certainly not
going to be friendly neighbours’ conversation. There are other reasons advanced aliens may
keep their heads down. Self-preservation springs to mind: what if they’re trying to avoid being
destroyed or enslaved? Well, this seems legit because it’s the nature of evolution that we try
to protect our kind. Like a squirrel will protect a squirrel, and a parent protects its child.
Because they want their hereditary to go on. And that’s why they are discreet. But if they come in
contact with us, to prevent their civilization, they might destroy us, seeing as a threat.
One last convincing idea is that we might be completely alone in this entire universe. This
thought is scary! What if we are all that matters? What’s so special about us that we
are the only life in the universe? Are we the only ones looking out in a hope to find life?
Do we have to share this with anyone else? And if that’s the case
we have to prevent life in this universe and it’s our responsibility to sustain and maintain life.
We would have to become the first type 3 civilisation in this universe
and advance ourselves. Though humans have always considered themselves as special,
this idea is disturbing. We may be completely alone in this dark empty space? This might
give existential crisis to a lot of folks but the odds of this happening are very very low.
