According to physics.bu.edu, it says.
The second law of thermodynamics is one of the most fundamental laws of nature, having profound implications. In essence, it says this:
The second law - The level of disorder in the universe is steadily increasing. Systems tend to move from ordered behavior to more random behavior.
One implication of the second law is that heat flows spontaneously from a hotter region to a cooler region, but will not flow spontaneously the other way. This applies to anything that flows: it will naturally flow downhill rather than uphill.
If you watched a film forwards and backwards, you would almost certainly be able to tell which way was which because of the way things happen. A pendulum will gradually lose energy and come to a stop, but it doesn't pick up energy spontaneously; an ice cube melts to form a puddle, but a puddle never spontaneously transforms itself into an ice cube; a glass falling off a table might shatter when it hits the ground, but the pieces will never spontaneously jump back together to form the glass again. Many processes are irreversible, and any irreversible process increases the level of disorder. One of the most important implications of the second law is that it indicates which way time goes - time naturally flows in a way that increases disorder.
The second law also predicts the end of the universe: it implies that the universe will end in a "heat death" in which everything is at the same temperature. This is the ultimate level of disorder; if everything is at the same temperature, no work can be done, and all the energy will end up as the random motion of atoms and molecules.
A measure of the level of disorder of a system is entropy, represented by S. Although it's difficult to measure the total entropy of a system, it's generally fairly easy to measure changes in entropy. For a thermodynamic system involved in a heat transfer of size Q at a temperature T , a change in entropy can be measured by:
The second law of thermodynamics can be stated in terms of entropy. If a reversible process occurs, there is no net change in entropy. In an irreversible process, entropy always increases, so the change in entropy is positive. The total entropy of the universe is continually increasing.
There is a strong connection between probability and entropy. This applies to thermodynamic systems like a gas in a box as well as to tossing coins. If you have four pennies, for example, the likelihood that all four will land heads up is relatively small. It is six times more likely that you'll get two heads and two tails. The two heads - two tails state is the most likely, shows the most disorder, and has the highest entropy. Four heads is less likely, has the most order, and the lowest entropy. If you tossed more coins, it would be even less likely that they'd all land heads up, and even more likely that you'd end up with close to the same number of heads as tails.
With a gas in a box, the probability that all the gas molecules are in one corner of the box at the same time is very small (for a typical box full of 1020 molecules or more, incredibly small): this is therefore a low entropy state. It is much more likely that the molecules are randomly distributed around the box, and are moving in random directions; this high disorder state is a considerably higher entropy state. The second law doesn't rule out all the molecules ending up in one corner, but it means it's far more likely that the molecules will be randomly distributed, and to move towards a random distribution from an orderly distribution, as opposed to the other way around.
What is this means?
This means in plain words that everything is not evolving but going towards destruction or chaos.
Why is this important?
First, the second law of thermodynamics shows that nothing is evolving towards order but the opposite. It disproofs that evolution cannot be. Since everything is going to chaos, evolution can't be.
Charles Darwin book The Origin of Species introduced the scientific theory that populations evolve over the course of generations through a process of natural selection.
If evolution moves forward from a lower order to a higher order, it does not fit the second law of thermodynamics. Charles Darwin says that evolution is going from chaos to a more orderly system. The problem is that the Second Law of Thermodynamics indicated that everything is working towards chaos. This means not moving forwards but backwards structurally.
It is important to understand that Darwin's work is a theory while the second law of thermodynamics is a law of nature.
According to www.merriam-webster.com, a theory is an idea or set of ideas that is intended to explain facts or events, an idea that is suggested or presented as possibly true but that is not known or proven to be true, the general principles or ideas that relate to a particular subject.
According to www.merriam-webster.com, a law is the whole system or set of rules.
This is important because the theory is base on unproven facts of observation during the entire experiment.
According to www.merriam-webster.com, a proof is something which shows that something else is true or correct.
According to www.merriam-webster.com, an experiment is a scientific test in which you perform a series of actions and carefully observe their effects in order to learn about something.
While the law is a proven scientific experiment that abides to the natural presence of an state at any particular time.
Charles Darwin's observations is just a simple adaptation to an environment. This means that if one specie of bird in one island has a one type of beak and the same specie in another island has another, it does not mean that the bird stops being a bird of the same specie. It means that the specie did not change but a feature changed. A human is a human here or in China. One man might have Asian features while the other has European features, but both type of man are the same specie. There has not been any plundge proof from one specie to another. Therefore, a monkey is a monkey and a man is a man.
Second, the second law of thermodynamics indicates that chaos is driving humanity towards destruction. Therefore, the second law of thermodynamics can be apply to Morality. As time passes, the morality is moving towards chaos. This means your heart becomes callous and harden. That is why the Bible shows us to guard our hearts
Proverbs 4:23 "Above all else, guard your heart, for everything you do flows from it."
Philippians 4:6-7 "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus."
