Not Evidence For Design

I’ve just had my regular visit from the Jehovah’s Witnesses. And of course they left the latest copies of their propaganda magazines, The Watchtower and Awake!

I always read them before they go into the recycling bin, just to see if there is anything that makes sense to a thinking person, although their main value is to give an insight into the irrationality of the believing brain. These magazines are just apologetics, mostly, and seem to be aimed at believers rather than anyone else. For those who already believe, and who like to have reinforcement of those beliefs, they serve a purpose. They might also be aimed at impressing potential converts, of course.

Something jumped out at me in this month’s Awake!, however. It’s an interview with an actual physicist who converted to the Jehovah’s Witnesses in 2005. He says he used to believe in evolution, but later concluded that life was created. I’ll not embarrass the fellow by naming names, but if you come across the July 2014 edition, you can read the interview on pages 12 and 13.

Incredibly, an actual physicist – who says that his job is to understand nature – shows the most profound misunderstanding of nature itself and the most basic laws of physics. He says:

As a physicist, my job is to understand nature. So I decided to give the facts some careful thought.

So what facts did he consider?

First, I knew that a closed system cannot become more organized unless acted upon by an external agent. That is the second law of thermodynamics. Since the universe and life on earth are highly ordered, I concluded that they must be products of an external agent, a Creator.

The second fact was that the universe and the earth seem to be specifically designed to support life. [Emphasis added]

In fact, the second law of thermodynamics says nothing about an external “agent” as such, and certainly not in the form of a creator, (or god). There are different ways that the second law can be stated but essentially it means that the total energy in a closed system will equalise over time until it is no longer able to do any useful work. It’s the same reason why perpetual motion machines are nothing more than wishful thinking: even the most efficient machines must eventually lose their energy into the rest of the system until they come to a halt.

It almost beggars belief that an actual Experimental Physicist can mangle one of the most basic physical laws. I checked around on the internet and found out that he is not just a physicist but a Senior Research Fellow in a British university, so it looks like the article isn’t a hoax – although I was wondering.

The second law is regularly trotted out by creationists as some sort of proof (they think) that evolution can’t be true. But it’s sad that their physicist has missed one extremely important point: the Earth is not a closed system. There is a constant input of energy from the Sun, so life on this planet is not falling foul of any physical laws, least of all the second law. As long as the Sun keeps shining, there is no danger at all of the orderliness of our system decaying.

The second point he makes is just another fallacy that creationists promote, the idea that “the universe and the earth seem specifically designed to support life.”

It’s another example of bad thinking. Look at it this way: if there is life elsewhere in the galaxy, it is unlikely to be anything like life on this planet. The environment that supports us could well be lethal to alien beings. And the environment on their planet might be lethal to us. There might be thousands of planets out there that are home to intelligent civilisations, none of which could survive for a minute on any of the other inhabited planets.

The point is this: the laws of physics apply all over the observable universe, so the emergence of life is probably inevitable. But those same laws don’t mean that there is only one type of environment that can support life. In the same way that life on Earth is extremely diverse, life across the universe is going to come in different forms too. If life can emerge and develop, it will evolve to fit into the environment it is in – not the other way round. The tendency is for believers to assume that the environment is there for the needs of the life within it, but the reality is that life adapts (evolves) to a changing environment, or it dies out. Nature has no feelings on the matter.

Our physicist then goes on to contradict himself, although it’s subtle and it will go unnoticed by the scientifically illiterate faithful, of course. He was “intrigued” by the Bible’s creation account and its reference to light:

“God said: ‘Let there be light.’ Then there was light.”

He then goes on to state the obvious: plants need light to produce food and we need light to see. And he goes on to say that ultraviolet light is good in small amounts, but dangerous if we get too much.

Yes, that’s true enough, but he acknowledges here that there is a constant stream of energy reaching the Earth from the Sun – the very thing that ensures that the second law is not going to spell our doom (for a few billion years anyway, at least until the Sun runs out of fuel and dies).

Sometimes I despair, especially when a qualified scientist (a physicist, of all people) who knows better, is willing to overlook the science he is trained in, in favour of faith (a belief that is held without evidence).

One thing I think I can be sure about is that this physicist will not be teaching his students the Jehovah’s Witnesses version of physics in an actual university lecture theatre. He will be obliged to teach physics, not religion.

Then again, it would be interesting to see what his peers would think of his research in this kind of scenario:creationism-cartoon-a-miracle-occurs

The advantage of an article featuring a scientist for any religious organisation is that it gives a false impression that science itself somehow confirms the religious beliefs of that organisation. Unfortunately, this scientist is not using science in this instance; he has allowed his beliefs to override his logic, and he just gives a superficial and false sense of authority to his church’s doctrine.

Religion and science just do not mix.
