As a child, I would look forward to
the summer when I would go upstate to camp. It was a time to get out of the
hustle and bustle of the city and the constant overbearing human presence that
occupied every inch of it. It was a time to get lost in the woods and see the
world for what it truly was. I loved every aspect of it, the smell of the
trees, the sounds of the birds and bugs, the simple chaotic beauty of the
forest. I felt truly at home. The true magic however came once the sun went
down and the stars would come out of hiding to reveal the true grandeur of
nature. I would sit there and just stare at them, transfixed like it was some
cosmic lightshow that I couldn’t peel my eyes from. From the Milky Way to
shooting stars, from planets to the seemingly infinite number of stars, I knew
them all. I knew their names, when they would show up, and were they would be.
The unobstructed night sky is truly the greatest motion picture of all time.
As
I grew older and stopped going to camp, it could be expected that I would
forget about them like I forgot so many other parts of camp. Instead however my
obsession with them grew, but instead of being content with just looking at
them and knowing their names I want to know what they are? Where did they come
from? How long do they last for? Can we go to them? Do they affect my life? Or
are they just a curiosity?
I now know that around 14.5 billion
years ago the big bang occurred. An immensely hot and infinitely small point of
pure energy exploded and expanded. For the next three hundred thousand years
there was nothing that we can even call matter. Once the first atoms of matter
formed, consisting mostly of just hydrogen, it just swirled around with no
discernible form for millions of years. Eventually however, the force of
gravity due to small inconsistencies in the density of the matter started to
pull it together. As matter started gathering into denser and denser lumps the
atoms started to fuse, igniting and releasing huge amounts of energy. It was
the age of the first stars and the universe was a mere three hundred million
years old. Those first stars lived fast and died young, collapsing into
supermassive black holes and it was around one of these that our milky way
first took form.
Let us fast forward through the ten
billion years or so during which our galaxy grew by eating all its surrounding
neighbors and growing to its current size of 120,000 light years across.
Billions of stars were formed and died and in their dying breath spewed out
huge clouds containing all the heavy elements past hydrogen they had created,
and then one day from one of these clouds our sun was born. Some of this dust
and dirt in this cloud however, never made it into the sun but kept swirling
about it like a huge disc. This dirt coalesced into larger lumps of material
which stabilized them into nice elliptical orbits around their star.
For the next 1.2 billion years our
solar system developed, dead and silent without a sign of life. The first life
was something we probably would barely consider alive if we saw it, but it was
from these humble beginnings on the relatively small planet we call earth that
we arose. The simplest one celled life first formed in the oceans and they were
the kings of the universe, its most complex life form for some 1.8 billion
years. As life continued to evolve it discovered all sorts of things like eyes,
mouths, hands, feet, sex, noses, ears, hunting, fruit, herds, and it kept
getting bigger, more sophisticated and more complex. Somewhere between 200,000
and 600,000 years ago (14.5 billion years or so after the big bang) the first
of our species, Homo sapiens, evolved from the earlier primates. This led to a
whole new form of living that involved social interaction, language, the
seeking and preservation of knowledge for its own sake, art, music, and for the
first time we had a creature that was conscious of its own mortality.
In 1988 (around 14.5 billion years
after the big bang) for the first time ever in the history of the universe, I
was born. I had not existed for any of the above mentioned events, and for that
entire time it had not bothered me at all that I did not exist. Even by the
smallest estimate the universe will still be around for at least another 14.5
billion years. If I am like every other living species that ever lived, for the
next (at least) 14.5 billion years I will not exist either. I do not see why
this should bother me at all.
