In science, a law is a proven hypothesis. In other words, it is an indisputable fact. The Second Law of Thermodynamics states that all matter is in a state of entropy, that is, it is breaking down or becoming less complex. Christians often use the Second Law to argue against Evolution, but say little about the First Law, which denies the existence of a Creator.
The First Law involves the conservation of matter and energy, and states that the sum-total of all matter and energy remains constant in a closed system. They can neither be created nor destroyed, but can only be transformed from one state to the other. Albert Einstein's Theory of Relativity (Energy = Mass times the speed of light squared) suggests that energy and mass are merely different states of the same thing. The problem with that is, the reverse should also be true (Mass = Energy divided by the speed of light squared), but it is not. Just as heat travels in only one direction, from warmer to colder, energy cannot be slowed down enough to produce matter. Shouldn't something be testable, and the test be duplicatable before it is call a law?
It is the First Law that has given rise to the fallacy that the Universe expands following "the big bang," and continues to expand until it collapses back upon itself due to gravity. Matter then eventually becomes so compacted that it explodes again. This is known as Pulse Theory, which is nothing more than an attempt to eliminate the need for a Creator. And while Pulse Theory seems to line up with the First Law, it fails to explain which of the two, the expanding or the contracting, is representative of entropy since nothing is lost in the process.
And why would the Universe begin contracting? Wouldn't the equalizing of the forces of velocity and gravity simply cause the Universe to become totally stable? The Moon orbits the Earth and because its velocity is equal to the gravitational pull of the Earth, it stays where it is. It is true that the Universe is expanding, but no one has observed it contracting. Someone once said, "God said, 'Let there be..., and BANG, it be!'" Who really cares whether God created the Universe as a minuscule dot of matter and then exploded it? I can accept that He may have used that method to produce the Universe, but He still created that minuscule dot and it still only took six days! And, there is absolutely no evidence that a contraction of the Universe will occur.
"So called science" (1 Tim. 6:20), has been the tool of Satan from the beginning. He enticed Eve to test her theory that eating the forbidden fruit would prove deadly (Gen. 3:1-7). The Theory of Evolution and Pulse Theory are Satan's attempts to create doubt in the revealed Word of God. It amazes me that both are called "theories" and yet they are treated as laws. Need I remind you that the Law of Gravity was broken by walking on water and ascending into heaven? Water was turned to wine, food miraculously multiplied, lepers were made cleaner than when they were born, and the dead were raised to life. Praise God and tolerate science; the truth will soon be revealed!
