Theist Cosmology: As Long As God’s Necessary Somewhere

Question from Physitheist:
I’m going to start this by saying that I’m a Christian, but also someone who believes in science…Here’s my question. According to the laws of thermodynamics energy moves to heat. Also there is no process that is truly reversible because we can not reach absolute zero, and the process would take infinite time. Since entropy continues to increase, and there is a limit of mass and energy how are we here? If there is not a limit of energy and mass, then why do you think so? And if you believe that energy and mass can appear out of thin air balanced out by anti matter why haven’t we ever seen this? After all the amount of unusable heat created is enormous. So basically my question is this, given the laws of thermodynamics, if you extrapolate to the size of the universe how are we here? After all the Big Crunch theory doesn’t really solve the energy problem since no process is 100 percent efficient. We’d still only have heat since there’s no such thing as negligible when the scale is eternity.

Thank you, and have a wonderful day!

Jesus loves you!

Answer by SmartLX:
I answered a similar question in my piece The World of Leftover Energy, so you can comment on that one if you like. Here I’ll just try to address some of your specific points and questions.

If you extrapolate the laws of thermodynamics regarding entropy to account for the entire universe they need to be applied as to a closed system, because we’re not aware of any energy leaving the universe. A hypothetical Big Crunch takes all the matter and energy there has ever been and jams it back together in a singularity – even the “lost” energy that’s been radiated outwards throughout the history of the compressed universe. That could actually achieve 100% efficiency through recycling, as literally no energy would be lost and the singularity could behave exactly the same as the previous singularity.

There is most likely a finite amount of matter and energy in THIS universe. If it’s the only universe, an eternal existence would have to depend on some form of reclamation, like the Big Crunch, or an exponential decrease that never hits zero, like I describe in the other piece. If there are other universes, as many have theorised and some evidence actively suggests, then it’s very possible that the total matter and energy in the multiverse is infinite, and entropy doesn’t mean much on the grand scale. I don’t feel the need to declare one or the other scenario more likely. An eternal universe isn’t certain in the first place, but a non-eternal universe doesn’t guarantee an eternal creator god.

Think about what would happen if a small group of matching matter and antimatter particles suddenly emerged naturally somewhere on Earth, and therefore in an environment saturated with existing particles of matter (e.g. air, water or earth). The antimatter would be annihilated by the existing matter in an instant, and the matter it touched would also be annihilated, so you’d be left with no antimatter and exactly the amount of matter you started with. It could be happening all around us and we’d never detect it without precise instruments. This isn’t proof that it happens, but it makes it impossible to say that it isn’t happening.

Louis Pasteur on Life

Question from Truk:
Evolution directly contradicts Pasteur’s laws, that state life can only come from life, as well as the laws of thermodynamics. Why does evolution, a flawed theory with more holes in it than a sponge, still stand, when it contradicts proven science?

Answer by SmartLX:
If evolution contradicted proven science, it wouldn’t still stand. That’s the whole point of science: if it’s proven wrong, it changes. The biology departments of the universities of the world don’t have the resources to maintain a massive conspiracy to prop up a bogus theory, but they have the evidence to support a sound one.

Thermodynamics first: you haven’t specified which laws you think evolution contradicts, so I’ll assume you mean the Second Law of Thermodynamics. There are several creationist arguments based on this idea, and I’ve addressed two of them here, here and here. If I haven’t covered your specific objection, comment and tell me what it actually is.

Now for the less run-into-the-ground material. Louis Pasteur only produced one “law”, and even that is only tentatively attributed to him: the Law of Biogenesis, which states that life can only come from other life. Pasteur did make such an observation, whether or not he made it official. The competing hypothesis of the day was spontaneous generation, the idea that life springs from non-life everywhere, all the time. People used to think that a bag of grain would spontaneously generate maggots, for instance. Pasteur examined many apparent examples of this, and in every case discovered that life was somehow getting in from outside and propagating.

Pasteur did not demonstrate, nor could he have, that it’s impossible for life to emerge from non-life in any circumstances. He simply established that it does not happen in everyday life, and that the life all around us is far more connected than people once thought. If genetics had been further along at the time he could have known this for certain, because all known life is genetically related and therefore descended from a single organism, a common ancestor.

This fact has an important implication: all life on earth can be explained by a single ancient event of abiogenesis (literally genesis from non-life). This means it’s to be expected that the circumstances in which abiogenesis can occur are incredibly rare, and might not even exist in the present day. However, given a billion years, half a billion square kilometres of surface area and countless different chemical compounds on this planet, it’s not unreasonable to suppose that the elements of life came together in just the right way, at least once. Living tissue doesn’t contain any element which isn’t also found in non-living material; it is literally made of the things around it.

Abiogenesis isn’t part of the theory of evolution anyway, because that’s only concerned with what life has done since it came about. Even if a god had created the first living thing, evolution could have occurred from then on without the god’s help, producing all the diversity of life from that single organism. This isn’t important to you though, Truk, because you want to establish that at least some part of the process was impossible without divine help, necessitating the existence of the divine. Abiogenesis, while unlikely in any single moment and circumstance, is not so unlikely that it can’t have happened naturally at all, so a god isn’t needed there either. Better keep looking for a spot to force one in.

Thermodynamics (it’s not what you think)

Question from Anon:
Hi,

I’m engaged in a discussion with a Christian friend of mine who has presented this syllogism to me:

“1. Simply put, if there is no external cause of the universe, then the universe is either eternal or self-created.

2. But, it is cosmologically ridiculous and anti-scientific (i.e. against laws of thermodynamics) to propose that the universe is either eternal or self-created.

3. Therefore, the premise that there is no external cause of the universe must be false (i.e. there must be an external cause for the universe’s existence, e.g. God)”

I believe he is applying the law where it can’t be applied, but I’ve never extensively studied science in college so I’m not really sure.

My rebuttal was that the universe was not necessarily a closed system and he responded with this:

“I have to remind you that my academic background has required me to not only understand, but apply, thermodynamics. [He has an engineering degree.] I know what the 2nd Law of Thermodynamics means and it clearly eliminates the concept of an eternal universe. If there is any misunderstanding on my part, it is in what you mean by ‘the law of the universe.’ Further, whether the universe is a closed system or not is irrelevant, since the concept of a closed system is theoretical, i.e. we have never actually observed a closed system.”

Thanks and I hope you can sort this out for me.

Answer by SmartLX:
Well, it’s not the usual creationist argument that evolution breaks the 2nd Law simply by producing order, so at least it’s a change.

He’s got one thing right, the universe is unlikely to be self-created. We don’t know of anything that is, or even what that would mean if it were true. For an entity to be the reason for its own existence would require an exception to the idea that an effect follows its cause. Rather than call this ridiculous, however, I’d just say that time would have had to behave non-linearly near the beginning. It’s strange to consider, but it hasn’t been ruled out as far as I know.

To set up the next option a bit, an eternal universe would need to be one where multiple Big Bangs happen in sequence. We have to work from the scientific fact of the Big Bang to achieve a plausible eternal model, especially after Borde, Guth and Vilenkin successfully ruled out the leading eternal models that didn’t involve singularities.

Your friend’s thermodynamic objection to an eternal universe is that any process that’s already been running forever should have run down by now, because no process is perfectly efficient. There are at least two scenarios in which this is averted (possibilities only, mind you):
– The singularity that immediately precedes each Big Bang reclaims all of the matter and energy in the universe by bringing space itself back to a central point. This includes all of the “lost” energy that radiates from decaying systems and is normally declared unusable, so in the end nothing is truly lost and the universe really is perfectly efficient.
– Extending upon your friend’s response, not even the universe itself is a closed system. It receives energy from an outside source, such as other universes. If there is an infinite number of these as some have hypothesised, they can keep a universe such as ours going indefinitely. (If one takes “universe” to mean everything that exists, in other words the whole multiverse, then the idea is available that it may contain infinite matter and energy, and never have to run down for this reason instead. It’s all a matter of perspective, and to some extent semantics.)

As an afterword on eternal universes, it’s worth asking your friend exactly how he exempts his eternal God from the 2nd Law of Thermodynamics. I hold it to be true that whatever constraints you place on the universe to necessitate a god, you immediately have to break them to allow for the god, usually by way of special pleading.

Moving on to the third option, it’s telling that your friend’s syllogism uses “e.g.” and not “i.e.” to invoke God. God is an example of an external cause, not the only possible one. The alternative suggested by the above is a concurrent or previous universe, which is part of a great many theories out there. I would love to hear your friend’s reasoning that starts from the external cause at the end of the syllogism and arrives at the Christian God, because at a glance it’s far from a logical step. (The following isn’t a scientific argument, but additional universes seem a more plausible thing to posit than a god because at least we know there’s such a thing as a universe. If your 5-acre cabbage patch has been devoured and you find one fat little rabbit in the corner, you don’t suppose that Bigfoot ate the rest; you wonder where all the other rabbits are hiding.)

Finally, there is a fourth option not covered by the syllogism: that the universe simply came into being without being created, that the common straw-man concept of “something from nothing” actually happened. Something like this is put forward in Lawrence Krauss’ new book A Universe from Nothing; specifically, that the precursor to the universe in certain models could be thought of as “nothing”. Even if you don’t accept this as quite the same thing, it at least advances another alternative external cause to compete with God.

Most of the options are essentially still on the table, despite your friend’s attempt at an argument by elimination. Even the option he wants to be left with doesn’t help the case for God very much, if at all.

Evolution: The Fossils Say Nothing, ‘Cause They’re Dead

Question from Thinkingman (in an unapproved comment last week, rescued from the static archive of the old site:
When “The Atheist” was asked if he believed in evolution he replied, “of course I do” as though evolution was as provable as “gravity”. If that is the case then
1. why are scores of very accomplished scientists moving away from the ‘theory of evolution” toward intelligent design?
2. And how can the “theory of evolution” be considered real science when it contradicts the second law of thermodynamics or “entropy”?
3. And how can evolution be accepted as an immutable fact when there are no fossil links that have ever been discovered indicating one species has morphed into another? There should be tens of millions of such fossil records.

Answer by SmartLX:
Seriously, people, it’s just an archive now. Comments aren’t approved there anymore. I go and check for new ones sometimes, and bring them here if they’re worth answering, but it’s not a reliable way to make yourself heard. Comment here instead.

As is my habit, I’ve added numbers to Thinkingman’s questions for easy reference. All three are classic creationist talking points, and answers to all three in their stated forms are widely available – which means the important thing to Thinkingman is not to find answers, but to disseminate the questions as widely as possible, to help them persuade the uninformed. Unfortunately for that cause, ask [questions] and ye shall receive [answers].

1. Yes, scores of accomplished scientists reject the theory of evolution by natural selection and embrace the hypothesis of intelligent design or ID. (For those who criticise evolution as being “only a theory”, remember that ID isn’t even that.) “Scores” is fairly accurate, because it literally means multiples of 20 (“four score and seven years ago” means 87). The Discovery Institute’s famous 2001 petition A Scientific Dissent From Darwinism collected the names of just over 200 biologists, while the other 500-600 signatories were in unrelated fields (making their “accomplishments” largely irrelevant). Even in the United States, where acceptance of evolution is badly affected by a high rate of religiosity, about 0.01% of biologists appear to oppose it. The scientists in relevant fields who do reject evolution remain statistically insignificant, and their numbers do not seem to be growing in relation to the total.

2. The theory of evolution does not contradict the second law of thermodynamics because, despite the creationist assumption, the second law of thermodynamics does not completely prohibit the emergence of order from chaos. This law merely requires that any new order in a physical entity is balanced out by an increase in chaos or entropy in another entity connected to it by a transfer of energy. Our sun is a raging, barely-contained nuclear wildfire which bombards us with energy, so there’s no problem.

3. So-called transitional fossils are largely a matter of definition. It can be argued that fossils of any species no longer living are transitional fossils, because they capture the species in the process of changing from whatever they were previously into whatever they became.

What creationists generally expect to see in a transitional fossil (and celebrate when it isn’t found) is the properties of a hypothetical trans-genus hybrid, or chimera. The commonly ridiculed example is Ray Comfort’s crocoduck, which demonstrates the unreasonable assumption most often made: that a transitional fossil should show one modern animal “morphing” into another. Modern creatures are distant cousins of each other, not ancestors and descendants, so one would never become another.

Regardless, comparable processes of pronounced physical change have occurred over geological time, and they are very obvious in certain fossilised animals. Here are the two most famous examples:
Ambulocetus, literally a “walking whale” with identifying characteristics both of modern whales and of the quadrupedal mammals from which they evolved.
Tiktaalik, a creature partway through the process of evolving from a fish into a four-legged amphibian. (For more detail on Tiktaalik and much more evidence for evolution besides, read Your Inner Fish by Neil Shubin.)

This is all basic, well-known stuff, but I’m of the opinion that it benefits the cause of reason to increase the rate at which supposedly rhetorical “challenge” questions are accompanied by straightforward responses when they appear. The above does just that.

Entropy 101

Question from Jack (reproduced from a comment in the archive):
I’ve spent some time reading about evolution and creation. I’ve read several pages about entropy and I can’t seem to find one that makes sense. Can you explain entropy to a poor retard like myself?

Answer by SmartLX:
It’s a difficult concept, and most of us have to make do with an approximation, so here’s mine.

Imagine the process by which objects with some physical order (structure, symmetry, smoothness, etc.) break down over time (decay, melt, crumble, evaporate, rot) into substances which do not have that initial order (powder, gases, liquids, mush). They’re moving from an ordered state towards a more and more unordered state. Entropy, as a quantity, is the extent to which this has already happened at any given time. About the closest thing to a synonym for it is “loss of order”.

If entropy increases, order has been lost. If it decreases, order has emerged or been created. The point of the Second Law of Thermodynamics is that entropy can’t decrease without increasing by at least as much in some connected object or area. In other words, it can’t decrease overall in a closed system.

The corrupted version of this law used by creationists is effectively that entropy can’t decrease at all without divine help. Alternatively they accept the law, but claim that the Earth is a closed system and any fresh order on it must be gods’ work. The response to the latter is to point out that the sun is part of any closed system which includes us. The thing runs on explosions, causing massive amounts of entropy. It sends some of the resulting energy our way as light, heat and radiation so that we might undo a tiny fraction of that entropy. That’s the connection.

A more general response is that if you think entropy is decreasing in a closed system, it’s likely that the system is not really closed.
