Entropy is a term generally used in physics and engineering. Here’s is what I guess you would call the strict definition:
A thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system
Got it? Sure you do. Entropy has lots of definitions. Google ‘entropy definitions’ and click ‘more’. All the definitions relate in some way to the above mouthful. But I want to talk about what I consider the broadest possible defintion:
Lack of order or predictability; gradual decline into disorder
The first thing they teach you in physics is ‘nature abhors a vacuum’. The natural order of things is for matter to fill every hole in the universe. Left to itself matter would be spread evenly and uniformly and boringly throughout the universe.
Every element has a half life. Every element is in decay, progressing from complex to simple.
And that’s the way of the universe, the way of all matter. From complex to simple. Entropy.
Except here. Here on this earth the natural progression is backwards. The direction seems to be from simple to complex.
Let’s look at evolution. I know we don’t want to but we must. Let’s say that there was a primordial soup and somehow this developed into complex amino acids. And let’s say that a spark of some kind struck this soup and life came about. Entropy says that this life would have almost immediately been snuffed out, that it would have moved from complex to simple. But that didn’t happen. Instead this simple spark of life grew and reproduced and became multicelled and developed a nucleus and a nervous system and evolved into giraffes and crocodiles and polar bears and viruses that can mutate and become resistant to antibiotics.
And people. This spark evolved into people. That may be the way it happened but it seems backwards. The way things work is from complex to simple, not the other way around. It seems backwards and counter intuitive.
This whole world is a miracle. From simple to complex. Life doesn’t just have a toehold on this world. The earth is lousy with life. Think of the most inhospitable place on this planet. There is something living there.
Entropy doesn’t apply here. The earth is a miracle.
