The First Law of Thermodynamics is the law of the conservation of energy. This law states that the total quantity of energy in the universe is constant. Energy may be transformed from one form into another and energy may be transformed into matter and matter into energy, but the total quantity remains constant—energy can neither be created nor destroyed. The first law has given an excellent account of itself not only in experimental tests of its veracity, but also in serving as a foundation for developing a quantitative understanding of many different branches of physics.
While the first law states that the amount of energy is constant, the Second Law has to do with the quality or usability of that energy—its availability to do work. As energy is utilized to perform work, some of the energy becomes unavailable to perform further work. In other words, energy can never be 100 percent converted into work. Even though the first law says that energy cannot be destroyed, the second law says that it does degrade, so that as energy radiates, less of it is available for mechanical work.
It was later discovered that the Second Law could be applied to problems relative to the energy required to construct and maintain complex systems. It was noted that all organized complex systems tend to become more random and more disorderly. It is easy to see why this is so.
The construction and maintenance of complex systems (systems meaning anything from molecules to machines to galaxies) requires the expenditure of energy, and as this energy is consumed to perform work, some of the energy becomes unavailable to perform further work, as the Second Law states. Thus the system tends to run down and deteriorate.
The term used to define this energy that is no longer available for work, and the resultant randomness and disorder in the system, is entropy. Entropy never decreases in any physical interaction. As things run down, deteriorate, and decay, their entropy increases. It has been found through observation and experimentation that the second law applies to all natural processes. Natural processes are inefficient. There is a waste of energy in any natural process. As more and more energy is utilized, more energy is wasted, and the entropy of the universe increases.
On the basis of evolutionary theory, the prediction is for matter to possess an all-pervasive tendency to increase in order and complexity. However, if we look at the natural world from common experience, or by the most sophisticated efforts scientists can arrange, it is apparent, first of all, that matter does not have an inherent tendency or intrinsic ability to transform itself from disorder to order, from simple to complex. No scientist has ever detected such a property of matter—it is not known in science.
The origin of information is another consideration, the importance of which cannot be overemphasized. Evolutionists believe that information has spontaneously arisen within systems with no help from the outside. Our human observations and experience tell us, however, that this never happens. These two laws of physics, therefore, preclude the possibility that evolution as described could ever have taken place.
