END OF THE WORLD: CHANGES
This, our physical world, is not likely to end in the foreseeable future. The proton, the neutron and the electron have enormously long lives. So, matter, as we know it, is unimaginably permanent.
In the nineteenth century, a number of physicists, like William Thomson and including Rudolf Clausius predicted, based in the Second Law of Thermodynamics, a Heat-Death (Wärmetod) when everything in the universe will be gone for good, and that will include our dear planet. Today physicists have other versions of THE END, but all in several trillion years.
And yet, planets will keep whirling for at least four billion more years. Current astrophysical theories and calculations suggest that the sun will bulge before becoming a red-giant in about four billion years, and in the process, gobble even Mercury and Venus.
So the question of the world coming to an end may be interesting from speculative and astrophysical perspectives but is really of little practical interest.
What is more observationally relevant is that everything in the world is constantly changing. We are not only changing but are also causing changes in small or great measure, the world around us. We are responsible for changes, major or minor, depending on our station in life.
Politicians cause changes: By oppressions, invasions, and passing or obstructing some laws. We all can do a little good for others with smiles and acts of kindness.
