It is
generally known that our universe contains billions of stars, our sun being one
of them. All those stars emit light because of their high temperatures, this
also means that life cannot exist on these stars. However, stars have other
objects like planets orbiting them, just like in our solar system. You would
think some of these planets must have the right conditions to create life, like
liquid water and having the correct light level. Eventually these life forms
should be able to evolve into more complex organisms and eventually into
intelligent species just like humans.
When we
look at the time it took for simple life forms to evolve into humans on Earth, it
only took 200.000 years, considering the age of the universe: 13.8 billion
years which means humans have been around for only 0.01% of the age of the
universe. If we are best the universe can do in 13.8 billion years, I’m quite
disappointed. There must be some other intelligent life form out there, right?
Or maybe there is another explanation for the fact that we’ve never come across
any alien.
One idea
which I personally really like is the idea of the universe being one big zoo in
which one superior race of aliens rules all others. This superior race would be
looking at us through huge telescopes, or maybe they would even visit the Earth
which would explain UFO’s, just like we visit zoo’s to look at wild animals. Perhaps
they even receive old television shows through the satellites we sent into
space, this way they study our appearance and behaviour.
Another
possibility would be that these aliens aren’t even trying to contact us but
they are trying to remain hidden. Why wouldn’t they have the desire to meet
other life forms like we humans do? Well, the answer is simple: these aliens
were attacked by another alien species which made them think all other life
forms are evil and want to destroy them. I’m just kidding, however it could be
a possibility, we don’t know. Perhaps they are way smarter than we currently
are and that’s the reason they don’t message us. One last possibility which in
my opinion is very likely is the fact that these aliens simply don’t have any way
of messaging us, their radio signals are not powerful enough.
Something
which is completely wicked, but very plausible, is the theory that all species
destroy themselves, every single one of them in the end commits suicide. There
are a few main possibilities for this to happened, the first being that each
intelligent life form creates some sort of mass-destructive technology.
However, this is only possible under one condition: this destructive technology
must affect every single organism living of the planet and it must also happen
to every single civilization. Imagine this would happen on Earth, however a
handful of people survive which are then able to reproduce themselves,
recreating the Earth’s population. Even if all humans are affected by this ‘’thing’’
but monkeys for example are not, their intelligence could increase again,
recreating an intelligent specie.
Of course,
the first mass-destructive technology which comes to mind are superweapons. In
the end, all life would use their intelligence to create weapons which would be
used in one final ‘’World War’’ to eliminate all life on the planet. On Earth this
process has already started. In fact, the nuclear war just after World War II,
could have been the end of human kind if the nuclear bombings would have kept
going. I’m not necessarily saying it needs to be nuclear bombs, for example
there have also been experiments with nitrogen bombs which actually did very
well. Perhaps there is a substance we don’t have on earth of that will be even
better at destroying life. Personally I really like the idea of some acid-bomb
that will shoot out all this acid whenever it explodes, anything in the acid’s
way will be melted.
A
completely different idea is that some kind of plague will evolve which will
wipe out all life. There have been some illnesses like the black plague (black
death) which wiped out over half of the population in some big cities.
Something like this could easily happen again, a new type of virus will destroy
human kind and possibly other life forms on Earth. Another option is that some
kind of mad scientist creates tiny robots which then destroy everything in
their path. Multiple movies have been made about such a plague, imagine if it
happens in real life; hell would break loose.
I think
either alien species aren’t able to contact us yet because they simply don’t have
the technology for it or that all intelligent life forms blow themselves up
using mass-destructive bombs. Let me know what you think is true, also if you
have any other ideas feel free to leave them in the comments below.
