many of us have often thought are we
alone is there life in our solar system
is there life in our galaxy is there
life anywhere else in the vast universe
given the size of the universe with an
unimaginable amount of stars and solar
systems there has to be life out there
somewhere surely in 1950 physicist
Enrico Fermi asked this question amongst
colleagues and quickly went to work on
calculations on the probabilities of
life existing elsewhere just in our own
galaxy the Milky Way which is thought to
contain up to 400 billion stars
estimations suggest there are roughly 20
billion stars composed just like that of
our Sun if just one in five has an
earth-like planet in orbit within the
habitable zone also known as the
Goldilocks zone where it is not too hot
or too cold
that would give us four billion planets
that could potentially support life if
just a mere Noor point 1% of these earth
analog planets do actually have life
within them then this amounts to four
million life dwelling homes if just 1%
of these planets contain intelligent
life comparable to humans that gives us
40,000 civilizations and if just 1% of
these civilizations were capable of
space flights and like humans our
explorers who want to expand to other
planets then there will be 400 whizzing
around in space around the Milky Way and
this is just from using low estimates
but the problem is we have zero evidence
that these calculated probabilities are
actually happening and this is the basis
of the Fermi paradox so where are they
there are many theories as to why we are
yet to detect any other forms of
intelligent life and these include we
are the first to emerge with technology
capable of transmitting and receiving
communications across space and
therefore it is currently impossible to
make contact
natural disasters such as super
volcanoes or large asteroid impacts are
wiping out developing civilizations
weather conditions and climates on other
planets could be too unstable to sustain
life long enough for sufficient
evolution development their planets is
poor on resources so may never have the
ability to progress technologically
other civilizations are choosing not to
look outward maybe we are just not able
to detect them through incompatible
technologies using methods and devices
we have no understanding of or you could
say completely alien to us other
civilizations that may have became
capable of communications have already
lived out their existence and no longer
exist
possibly by destroying themselves
through wars or with much more powerful
and advanced technology but should we be
able to see some form of evidence of
previous existence in the cosmos maybe
just maybe we are a fluke an anomaly and
are the only ones out there anywhere or
worse yet we could have been created
physically or virtually and are
currently being observed by a super
intelligent species hiding from us just
to see how we develop we could
potentially be some sort of scientific
experiments that could end any time it's
a scary thought whatever the truth
actually is we may never discover it but
that will not stop us from trying we
