Given that there are billions and billions of
galaxies out there and given that each galaxy contains billions of stars it
becomes incomprehensible that we are alone.
It is entirely possible that we are
accompanied by our travels through space at vast speeds by planets full of
microbes or bugs. On the other end of the scale there could be life out there
with technologies far exceeding our own.
But.
(There’s always a ‘but’.)
Shall we just consider that for a few moments.
We are reliable informed by ‘people that know’
that our universe is around thirteen (13.798 ± 0.037) billion years old.
It took, we are told by those same people,
many billions of years for the galaxies that form our universe to coalesce out
of the whirling mass of expanding soup thrown outwards by ‘The Big Bang’. Or
whatever.
There then followed several billions of years
for the solar systems to form within those galaxies. One of those systems was
ours.
It was only about four billion years ago (4.54 ± 0.05 billion years) that the Earth was formed as a glowing ball of molten
rock made up of materials manufactured within stars ‘out there’.
There followed an unimaginably long time in
which there were only simple cells that ultimately developed into plants.
Plants fired up the photosynthesis that gives us oxygen; oxygen enabled higher
life forms until, eventually, came beasts. Not like us, for certain, but
animals nonetheless. Their bones have been discovered and analysed.
This is only about six hundred million years
ago—not ‘billions’ but ‘millions’!
We have struggled out of the mud and gradually
developed until, in the blink of a galactic eye, we are here. ‘Ping’! Look,
Mum! Humans!
We have achieved our technology in the last
two or three thousand years. It is only in the last two hundred years that our
technology has taken on a life of its own and progressed in leaps and bounds.
The ‘American Civil War’ (how the Americans
love wars. If there is nobody else there to fight they will do battle with
themselves!) was the very first industrialised war—courtesy, in part, to the
Springfield Armoury.
Now we have all sorts of strange things
floating around in space above our heads.
The greatest of these is, arguably, the
‘Hubble Space Telescope’ that enables us to see, without atmospheric
distortion, into the great depths where, some day, we should hope to go.
So that is our history.
Let us, just for a few moments, think about
the history of some other, anonymous, planet.
It is unlikely that they would have developed
very much differently to us in the first instance.
The time taken to evolve into higher life
forms must be regarded as quite similar.
Logically, then, there would be similar
extinction periods caused by whatever it was that wiped out the dinosaurs here
on Earth. Perhaps they, too, suffered a massive meteor/asteroid strike or a
devastating volcanic explosion. Maybe they had an all-encroaching ice age that
reduced the food levels sufficiently to create an untenable environment for
certain beasts.
Eventually a life form would come about by
whatever means is appropriate to them that would have the ability to reason, to
think, to analyse and synthesise.
Tools would be developed. This happens quite
slowly until such time as there is some kind of industrial revolution that
creates an environment where ideas can be sent out quickly and efficiently.
Printing spreads thoughts and ideas as it also creates an opportunity for
universal education.
From this develops the idea of mass
production—not just vehicles but pens, typewriters. Electricity is discovered
and used in all manner of ways so that people now have light; working at night
is now a far clearer possibility.
Their technology accelerates at a rapid pace.
Perhaps they have fewer wars but that idea suggests that technology develops
more slowly. We need these people to develop their technological growth
extremely fast and so there must be wars, devastating wars that propels them
ever forwards into greater and greater discoveries until their social life
catches up and they discover that they can grow faster by cooperation, by
combining the thoughts of the best brains.
These people are now more advanced than we are
but are they sufficiently advanced to come and visit us?
Has there been enough elapsed time between
their origins and their current technology to hurl themselves through space
(and time, perhaps) to come and see what we, out on the fringes of the Milky
Way Galaxy, are doing?
The cost would be enormous. Why would anyone
choose our planet in the first place and then expend planet sized wads of cash
to come and see us and then not say, ‘Hello’?
There are, without doubt, people out there who
are looking up into their night sky and wondering if they are alone in this
great expanse.
Is their technology far enough advanced to
come here and visit us?
I think not. There has not been enough time
for them to develop sufficiently beyond our own efforts to come here and
compare notes.
‘Ancient Aliens’? A lovely thought and an
interesting take on the evidence but not, I think, hitting the mark.
Still, cutting a flat rock out from a blind
hole is intriguing; one wonders how they did that.
There are lots of mysteries out there but the
only star people who can solve them are us.
We cannot expect, or hope, for some master
race to come blasting from outer space to solve our problems.
Our problems are ours to solve and we really
ought to be doing that right away or there will be nobody for the master race
from space to visit.
