Order to disorder: there was a beginning!

So far we have shown that absolute truth exists and that it does matter what we believe. We can choose to believe what we like, but it would only amount to self delusion and most likely to decisions that would harm us at some point in our lives.

But what is The Truth about where we came from, and before we get into that… where did anything come from? Has it always existed in it’s current state? Has this planet existed forever?

The answer is no… and the proof is the three laws of Thermodynamics.

Thermodynamics: the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.

The laws of Thermodynamics were found empirically when engine designers tried to find the optimal steam engine, although the principals apply just as much to modern gasoline or diesel engines. The goal was to design an engine that would run forever without any additional fuel – a perpetual motion device. It was soon clear that this is simply impossible.

First Law

Energy cannot be created or destroyed in an isolated system

If we take the universe as the closed system – or even a supposed multiverse, for which there is no evidence. This law states that there are no natural laws in the universe that will create energy from nothing.

There are two possible explanations for what we find today then:

  1. Something outside the closed system put the energy within it
  2. or that energy has always been in the closed system

Second Law

Entropy of an isolated system always increases

Heat always flows from hotter to colder bodies, it never flows the other way. For example, if you leave your hot cup of tea on the side to goes cold… why? Because that heat spread out and warmed up the mug and then the air around the mug. If you leave your cold mug of tea out, it will never get warmer than the surrounding environment.

Natural processes work towards equilibrium, where the heat throughout the isolated system is constant. When there are no hotter or colder parts, all bodies within the system would be the same temperature. When that happens, there is no more usable energy within the isolated system.

While heat is moving it can produce work, drive the wheels on a car. That energy can also be converted from heat energy to electrical energy and used up elsewhere. But fundamentally once the energy has been used, it’s gone.

Entropy is the measure of unusable energy in a system. over time the energy is used up.

Returning to our list then, we can cross off option 2.

  1. Something outside the closed system put the energy within it
  2. or that energy has always been in the closed system

Why? Because if the energy had just always been in the universe, then there would now no longer be any usable energy left many many years ago. This is commonly called universal heat death.

Third Law

entropy of a system approaches a constant value as the temperature approaches absolute zero

This third law doesn’t help any more than the first two. Basically entropy can be slowed by reducing the temperature, but even at absolute zero, it can never be reversed.

What do we learn from this?

There was a beginning, when something outside the closed system put the energy it now contains into it. The Bible says that something was God, the Athiest will say this was “the big bang” and whatever produced it?

Another important point is that natural processes move order to disorder. So if you make something and just leave it, then it will eventually rust away or degrade back to it’s individual components. It takes a lot of effort and work to maintain something, to keep it in good condition.

So ideas of matter self organising into complex biological organisms is the opposite of what natural processes do. Already this doesn’t look good for a naturalistic explanation of why we are here and where this world came from…
