I’ve been reading, lately, about the second law of thermodynamics. I guess physicists have figured out that the transfer of energy will invariably result in a net loss (you know, carbon emissions and such); entropy will invariably increase over time until heat distribution reaches equilibrium and the last star blinks out, which will occur, according to sound estimates, sometime in the distant future. That is, the universe will remain functional and in existence for a very, very long time. Physicists are pretty sure about this and who am I to question learned scientific minds.
No matter how dark things may look at present, even if the world we know and love loses its capacity to sustain life (through every fault of our own), there will, I truly believe, be stars somewhere out there supporting planets where life will be sustainable. Stephen Hawking is pretty sure that, to his reckoning, we probably should be looking for such places in the interests of species survival.
I feel optimistic about such thinking: on a planet in a galaxy far away perhaps politics will be less offensive.
