The Milky Way-120,000 light years to travel its
length and 12,000 light years from top to bottom. The only know life in this galaxy is on
planet earth. For years, scientists,
psychologists, astronomers, and many more have been debating over one crazy
question: Does life exist outside of earth?
We are just a part of a one galaxy, which we have
not been able to even come near to exploring the whole Milky Way. Even in today’s world, with the booming
technology and sophisticated machinery, we have not even made a dent in
exploring the universe. In 1969, the
very first people made in onto the moon in mission Apollo 11. Since then, we have made lots of progress
technologically, but making it 300,000 miles to the moon is nothing compared to
the 40 million miles it takes to get to mars.
Mars is currently the best hope that NASA has of finding life on another
planet, because it is one of the closet planets to earth that we have not discovered
yet.
Recently, there has been a large debate of a meteor,
which supposedly hit planet earth in the Stone Age. The meteor is said to be full of carbon, and
have similar marks on it that microorganisms from earth make while eating
through rocks. Scientists are also
saying that they believe that water, a common necessity for life, was covering
the surface of mars, hundreds of thousands of years ago in the form of oceans,
rivers, and streams, like on earth. This
discovery does not only suggest that there has been life on mars, but comes back
to show that life in another galaxy is a reality.
We live in one galaxy, which we don’t even know if
life exists on, or has existed on. NASA
has estimated that there are hundreds of millions of galaxies in the universe
which never really ends. If there exists
life on our galaxy, the Milky Way, chances are that life exists on others as
well. Life doesn’t mean people who look
like us, or even aliens. It would be extremely
fascinating if there was even an organism out there, even the size of bacteria.
Think about it, billions upon billions of galaxies
in the universe, more than we can even fathom, odds are that life exists in
several hundreds, if not thousands, or maybe even millions of galaxies. It really is crazy to think about, another
being, besides yourself, living out, billions upon billions of light years away
from you, thinking about if life exists on another planet, or if they are just
alone as well. They says the sky is the
limit, but I say there is no limit.
