A Precious Human Life – in our time

Human beings have been around for a very short time and Earth is a relatively new planet. Science has yet to discover the many thousands of species here on Earth, even the depths of our oceans have hardly been researched.

It is interesting to know that we all came from the same single cell and we are 99.9% identical in every way to each other human being who has lived, died and is part of the human race. Remarkably, we share  many similarities with so many other people but even within this 0.1% there is tremendous variation. Some people are more fortunate than others, yet we all experience similar things at certain times; pleasure, pain, sadness, love, hate etc. We all share the very basic needs of food, water, shelter, sense of purpose and belonging etc. With all this humanity it is mind-blowing to note that all of it will one day end.

Our Sun will die. The death of every other of the 200 Billion stars in our galaxy alone will go out as will all stars in the universe. They will extinguish any possibility of life anywhere within the universe. This means that the universe will remain disordered, cold and full of radiation forever. It’s written into science as an inescapable fact that the cosmos will die, nothing will survive. Millions of extra-terrestrial lifeforms that potentially exist on other planets out in the vastness of space will also perish.

The conditions for life in the universe are incredibly minute. The sequence of events that create the death of the universe are the very same things that make life possible for the briefest periods of time here on Earth. It takes time for gravity to pull planets together. It takes time for mountains to form and trees to grow. It takes time for civilizations to evolve genetically.

Our Sun is a great example of a perfect condition for life. Earth is at the right distance to sustain life, just a small veering from this perfect distance and life would be vastly different. But this star will not always be here. It will eventually die. Long before this, man will have died out from the extreme heat of the growing Sun. There will be no conditions for life on planet Earth.

As a fraction of the lifespan of the universe as measured from its beginning to its end, to the evaporation of the last black hole, life as we know it is only possible for 1/1000th of a billionth, billionth, billionth, billionth, billionth, billionth, billionth, billionth, billionth percent.

Trillions of years along the arrow of time, the universe itself will have all but faded out – there will be no energy to sustain anything whatsoever. No new stars will be born and all lifeforms on the various other planets throughout the universe will also be extinct.The billions of different species will be no more.

I am sure you agree, that makes your life a pretty rare miracle. This is not a depressing thought, but one of great appreciation and awe that we are here right now under almost unbelievable circumstances.
