It's life Jim, but not as we know it.
Very late in life I have become a
philosopher. It doesn't pay much, but it helps to pass the time.
So, what has brought me to this late,
great career change?
I was musing (as you do in your dotage)
about the arrogance of the human species. Particularly I was
thinking about religion and disaster movies. An odd combination –
as well you might think.
It seems that humans have an innate
capacity for doom-mongering and pessimism. Given a modicum of
encouragement, we will cheerfully forecast the end of civilization,
the beginning of a new Ice Age, global warming destroying the planet
(Soylent Green style!), shale gas fracking causing planetary
cataclysms, etc. - and the et etceteras are manifold.
However diverse, these dooms, for which
we are seemingly unable to escape, have one unifying feature. We do
survive. There is always some remnant of homo sapiens who rebuild
the planet and some sort of civilization. We endure. We go on. Our
grand children’s grandchildren are born and live their lives. We
assume that throughout the débâcle the human species goes on.
It occurred to me that this is not
inevitable. There are disastrous scenarios where we do not survive.
For example, take our Sun – Old Sol.
It's been cheerfully chugging along for billions of years providing
us with all the energy needed for life on our planet to develop and
be sustained. It does so with such predictable regularity we assume
it's continued predictability is inevitable. It is not. Sometimes
stars go “wrong”.
Although this is a remote possibility,
it is still a real possibility.
From Wikipedia
“Although no supernova has been observed in the Milky
Way since Kepler's Star of 1604 (SN
1604), supernova remnants indicate that on average the event
occurs about three times every century in the Milky Way.[5]
They play a significant
role in enriching the interstellar medium with higher mass
elements.[6]
Furthermore, the expanding shock waves from supernova explosions can
trigger the formation of new stars.”
A comfort, but not an absolute
guarantee. Most likely we will have destroyed the planet long before
the sun jumps in and does us the favour.
But there is a quantitative difference,
other disasters are for the most part survivable. The sun going nova
is not.
And here's where philosophy and
religion come in. We are often reminded that we are just a speck (
and a very small one at that ) in the cosmos – an insignificant
little planet orbiting a very ordinary star.
Except for the earth ending in a kind
of Hitchhiker's Guide to the Galaxy Vogon induced way ( read the book
if you don't know what I'm taking about ), we will all die in the
nova explosion and, more importantly, so will all evidence that we
were ever even here. That's a sobering concept. Imagine some
time-warping space traveller arriving in our vicinity some billions
of years hence. All that's left is a cloud of dirty dust where our
solar system used to be. Everything ever known about the earth and
the creatures it once sustained is gone and cannot be reconstructed.
It is, for all practical purposes, as if we were never here at all.
This is not science fiction – it's
science fact. Nova do occur in the galaxy at a somewhat predictable
rate. If we are “unlucky” enough to become such a statistic then
it's just hard cheese. We can do nothing about it. Our only hope
then is the Voyager 1 ( http://voyager.jpl.nasa.gov/
) which may, with luck, be found in a distant galaxy in a distant
time and cause some real consternation among whichever of God's
creatures it ends up.
Training their telescopes on the star
pointed out in the diagram plastered on the side of the spacecraft,
they might just make out a small nebula and puzzle about who ( or
what ) might have made the odd craft they have discovered. ( I
suspect our own reaction would be the same should an alien Voyager 1
turn up tomorrow! )
Using the newly acquired Philosopher’s
Stone I earlier alluded to religion now becomes far more than the
opiate of the people – it becomes imperative for remaining sane.
Leaving aside the objections of The God
Delusion and the Voyager spacecraft,
(
http://en.wikipedia.org/wiki/The_God_Delusion
) we now need a Supreme Being in order simply to have a little
confidence in our existence at all.
This may not scare you – but I
confess to looking at things in a slightly different way.
