2nd Law of Thermodynamics


I have a close friend that is a Christian apologist (Christian apologetics is a branch of theology that defends Christianity against objections). For years he has been using the 2nd Law of Thermodynamics to prove the start, end, and creation of order and chaos. The first time he used it, I was unfamiliar with the concept. Since then I have looked it up several times, and I always have difficulty grasping and retaining what the 2nd law of thermodynamics means.

I finally understand it where I can briefly explain. This first part is more informational than a rant, but I'll post it anyway. This is a slightly modified email I sent. My rant will be below!

I used three videos from Khan to refresh (I recommend watching all three for a better understanding), along with an occasion google search to confirm my understanding was mostly accurate. I recently read a book called The Order of Time, it had the best description of the 2nd law I came across at the time. 

Info on the 2nd Law of Thermodynamics


The 2nd law of Thermodynamics explains that, “we don't see a spontaneous transfer of heat from cold areas to hot areas… What we do observe is that if [we] were to put ice water in the middle of a room at room temperature, [we’re] gonna see the other way. [We’re] gonna see transfer of heat from the warmer regions to the colder regions.” The law is based on the transfer of heat from warm/hot to cold.

The transfer of heat leads to entropy. The 2nd law explains that entropy in a closed system only increases. Most scientist would consider the universe a closed system (deist that believe God interferes with the universe would make our universe an open system, and the 2nd law wouldn’t apply). If we consider the universe a closed system, the universe is constantly increasing in entropy. As the space of the expanding universe increases, so does the possibilities of different states. Therefore, the greater possibilities leads to greater entropy. The average temperature of the universe decreases, but the entropy increases because there is more space/possibilities of ordered states.

Rant Time

Christian apologists love the 2nd law of thermodynamics. It gives them a scientific argument for their God. Here is a good argument by Jeff Miller, a Christian apologists who has a PhD in engineering, click here for his article. It isn't bad.
"There are only three possible explanations for the existence of matter in the Universe. Either all of the mass/matter/energy of the Universe spontaneously generated (i.e., it popped into existence out of nothing), or it has always existed (i.e., it is eternal.). Without an outside force (a transcendent, omnipotent, eternal, superior Being), no other options for the existence of the Universe are available. However, as the Laws of Thermodynamics prove, the spontaneous generation and the eternality of matter are logically and scientifically impossible. One possible option remains: the Universe was created by the Creator."
Miller is referencing the first law of thermodynamics that states, energy cannot be created or destroyed. Miller's argument is still bad. He says the first two possible explanations are logically and scientifically impossible, but guess what? So is the remaining possibility. 

(side note) Lawerance Krauss wrote a book arguing how a universe could appear from nothing, and he is a theoretical physicist. So there must be some scientific possibility.

Miller makes a couple assumptions that are unsupported. The Big Bang theory describes the first moments in the universe, but it says nothing about what happened before. It's not that implausible to think the universe could have existed in some form prior to the big bang and rebanged. Also he describes the eternity of matter. Matter didn't exist in the first moments according to the big bang. Miller needs to explain more.

This is my problem with the few Christian apologists I know. They cherry pick science. Miller did too. He only applied scientific and logic to the arguments he was destructing, not his own. This is bad philosophy.

My friend who started my rant doesn't believe in science. Any science/theories that conflict with his beliefs result from wild conspiracies by secularists and atheists. 

Conclusion

My rant is losing steam, and in all honesty, I don't care. I'm in some universe, however it started, and knowing how it started and who did or didn't create it, isn't going to improve my life. Rant out!
