>>2866I myself have a limited understanding of it since I'm more of a mathematician than a physicist, but I believe that the 2nd Law of Thermodynamics states that in a given system, entropy (or the chaos of that system) will increase over time, correlating to OP's arrow of time - or the continuous change of matter. Basically, the universe will become more disordered over time and entropy is the movement of
particles particles's energy at an atomic level.
An example is if you drop a pebble in a pond, you'll see the ripples moving out. Even if you didn't see the pebble, you could see the ripples it made and conclude that the ripples will spread out until they reach the ends of the pond and that the rock was dropped at the point from which the ripples originate. If the ripples were going in reverse (towards the point where you dropped the pebble instead of away from it), you would realize that the entropy was reversed, which is impossible since it would mean that matter was acting in a way opposite to how it is destined to act and the energy was collecting itself in a way that it shouldn't be. This would entail that time was in reversal.
I think the guy in OP's image is saying that evolution cannot occur because it is a coming-together of entropy, which by its definition is supposed to be
matter's matter's energy's gradual tendency towards chaos.
My opinion: This assumption is flawed because entropy is subjective - if you think energy is gathered in a certain place and you call it organized, but someone else sees energy arranged in a different way and calls
that organized, then you have two definitions of what ordered energy is. If more people think other things about how organized energy looks, then we have even more definitions. It's incorrect to assume that because energy disperses or rearranges itself over time, evolution or a building of the perfect living being cannot occur. If anything, I think it would just suggest the randomness of evolution, though evolution has more to do with matter than matter's energy.
