An interesting theory has it that life evolved/evolves to dissipate gradients in nature, thermal, chemical, etc. In other words, the overall increase of homogenization and increase of entropy in the universe is assisted by the presence of life.

Sure, life dissipates gradients, as I said. A gradient is a kind of order. The Universe moves to a state of minimal order and maximum homogenization, which life assists in. "Nature Abhors a Gradient." Now where do Humans come into this? Well, we seem to be doing a pretty good job of it, don't you think? Burning up those fossil fuels is our big contribution to the overall scheme. This physical paradigm is completely atheistic, however, and I'm not certain of its ultimate truth.

There is no such thing as negative energy. It's saying that particles never have a velocity equal to zero, and you can't have negative velocity.

$this->bbcode_second_pass_quote('rogerhb', 'I') would suggest that the vast majority of the world's population survives for weeks on end without ever actually "thinking".

Repeating the same schedule as the previous week, week in, week out, going to work, coming home, eating, sleeping following the routine, all of this can be done without ever actually "thinking".


I agree, and I would suggest that the reason for this partially is that the vast majority of people exist in environments that don't require them to "think". Or, rather, there is no benefit or payoff to "thinking". Even when a real problem is considered, like crime, war, bigotry, or disease, most people, I imagine, end up thinking that "these are problems for the police, governments, sociologists, and doctors to deal with, I have to get this report done, the breakfast made, the kids to soccer practice," ad nauseum.

Tree of Life / Right Brain / Represented by the Goddess, the Wisdom, this type of thinking has been suppressed for at least 4000 years.

The overall scheme is simply balance, the paradigm thus shifts...

Is not moderation and balance important?

Or need I point out the excessess of western lifestyle poisoning the rest of humanity?

Namaste
You are all over the place, Raphael. Your particuar brand of 'cosmogony', i.e., your own private 'mythology' isn't of interest to me. I am simply pointing out how life and the evolution of life is indeed compatible with the Laws of Thermodynamics.

I agree with Pen. All you had to say is that an imbalance exists among the world in the distribution of resources.

I dont believe its anything against evolution, just a re-assetion that there is still a lot about the universe we dont have the faintest idea about. You can throw up ur hands in defeat and say the only explanation is God/gods, but I feel speculating on how 31st century physics might look like is pointless. :-D

To argue against evolution you will have to somehow show that the somehow evolution, change over time contradicts the second law, which u haven't. :)

$this->bbcode_second_pass_quote('Raphael', 'A')nd I believe once we reach a state of maximum entropy...an event occurs to reset the earth's entropy back to minimum.


There is no such thing as "entropy". Entropy was use for "machine" not for living thing... Even French are not stupid enough to get into this. Go read the history of “entropy theory”. Scientist used this theory for machine not for organic things. If you don’t believe that, fine. Be a fool.

Let me try and mention a few things about thermodynamics.

I hope I'm not being redundant, as I didn't have time to read the whole tread. I just post this because it can be of some help as to the relevance of thermodynamics for peak oil.

There are two types of energy: one type you cannot use to move stuff around (call it heat, or entropy or whatever you prefer), the other can be used to move stuff. The latter is usually called in physics "Gibbs free energy" or "free energy", for short.

While the sum of the two is constant in an isolated system (a system that does not trade matter or energy with its outside), the second law says that, in any process within that system, the free energy will decrease and the unusable energy will increase.

You're of course welcome to try and dispute the second law, but be warned some people have been trying that for 200 years now, with rather discouraging results.

Now, since we need to move stuff, we need free energy. Where do we get that? Well, you can get it from oil or any other fossil fuel you like. In this case two things can happen:

1. The amount of fossil free energy on the Earth is so large we can't exaust it within the lifetime of mankind, even if keep using more and more of it.

2. The present and future rate of consumption of fossil free energy will lead to its exaust at some stage.

Since scenario 2 is what is more likely to happen, we have to look for free energy from other sources. We usually call these "renewables". They feed on free energy coming, for instance, from the Sun or from Earth's rotation.

Basically, the second laws of thermodynamics isn't really important to peak oil. In a nutshell, the only thing it says is we can't make a car run on its own exaust fumes forever. While the fumes have free energy, the car moves. After that it stops. This only tells us what we already know from experience: we have to get our free energy from somewhere. Be it fossiles or renewables.

This is actually a fairly common argument, which, I'm sorry to say, is easy to refute:


$this->bbcode_second_pass_quote('', 'T')he universe is like a clock which is running down." But, the evolutionists say that the world has been building up from simpler to more complex forms over billions of years.


The universe and the world are not the same. The universe is winding down; the world still gets a massive input of energy from a source that is itself winding down--the sun. The world, and the things on it, can use this energy, though, to decrease local entropy over time.

$this->bbcode_second_pass_quote('', 'E')vidently, this view of the evolutionists is contrary to the well-established second law of thermodynamics.


Well, not really. For fairly complicated reasons, the second law actually predicts the formation of larger biological molecules. Basically, the sum of the energy of a given instance of modern human proteins is more spread out (i.e. has more entropy) than the sum of the energy in primitive bacterial proteins.

$this->bbcode_second_pass_quote('', 'F')or, in actual practice, we observe that the changes in the physical unvierse are caused by running down and not by building up. For example, complex atoms, like those of uranium and thorium disintergarate into less complex ones like radium or lead, but it has never been in the reverse order.


It clearly has been in the reverse order from time to time, else we wouldn't have Uranium or Thorium.

$this->bbcode_second_pass_quote('', 'T')he complex stars also break down into nebulae and this happens in a few hours’ time, as observed at present: it does not happen in millions of years.


1) Not all stars break down into Nebulae.
2) One should not assume that Nebuale are less complex than stars--they simply have a greater state of entropy. The subtlety in the difference between the two concepts is principally how this argument gets its erroneous boost.

$this->bbcode_second_pass_quote('', 'S')imilarly, the sun burns about 250 million tons of matter per minute. Such a huge process of annihilation must have been going on in the stars also, Evidently, it is not a process of building up of energy or of evolution of more complex forms but it is a process of dissipation and disintergration into simple forms.

Actually, we see new stars form from the remains of old ones; this process may or may not serve to invalidate or modify the second law of thermodynamics.

$this->bbcode_second_pass_quote('', 'T')he theory of evolution, being contradictory to this well-established law, is erroneous. Sullivan says, in his book ‘Limitation of Science’: "One of the least disputable laws of Physical Science states that the universe is steadily running down. We live in a wasting universe. But the fact that the energy of the universe will be more disorganised tomorrow than it is today implies, of course, that the energy of the universe was more highly organised yesterday than it is today. Following the process backward, we find a more and more highly organised universe. This backward tracing of time cannot be continued indefinitely. Organisation cannot, as it were, mount up and up without limit. There is a definite maximum, which must have been in existence a finite time ago. And it is impossible that this state of perfect organisation could have been evolved from some less perfect state. Nor is it possible that the universe could have persisted from eternity in that state of perfect organisation. Thus the accepted laws of nature lead us to a definite beginning of the universe in time."
In the light of the above, it would be only natural and proper to conclude that the theory of evolution is wrong and that the world has been undergoing a process of degeneration from Golden Age to the present Iron Age and this process has taken a finite period, extending over not millions of years, but only some thousands of years – 5000 years to be exact. Om shanti.

This is another well-known argument popularized (and rejected) initially by Aquinas. Why can't we have an infinite regression of time backward, where for some point x back to infinity, the universe existed with minimal entropy? Seems counter intuitive, but there's no proving that it couldn't happen. Claiming that it is impossible is equivalent to claiming that one can offer such proof, but it doesn't seem likely that such a proof will be forthcoming. In the absence of proof, the best we could say is that it seems nonsensical, but then, we've discovered all sorts of things about the universe that are nonsensical--my favorite being i, the square root of -1, which has real world application despite being an imaginary number.

-1 was itself once regarded as nonsensical. Negative numbers were 'invented' to solve equations such as x+2=1. Indeed, how can one 'add' something to 2 and get 1? Irrational numbers caused a crisis in Greek mathematics since they can't be written with digits in any number base system. Nonetheless x squared minus 2 = 0 requires a solution. So imaginary numbers are just an expansion of the number system to give solutions to certain kinds of equations, not necessarily 'nonsensical'.

If you have an apple, and leave it on the table, it will eventually rot.

And you could predict that the apple will rot.

So you could say leave the apple on the table and it's destiny is to rot.

But would you say that the apple has fulfilled it's role in life? Can now go to the next world sure that it will sit on the right leaf of the big apple?

Or would you say the whole universe was created so that we could have rotting apples?

$this->bbcode_second_pass_quote('Raphael', '

I love those popular writings of Physicists. Without them I wouldn't know too much about what's going on, and I scored at 98th percentile in the NTE for physical sciences and have completed enough upper division Mathematics courses for a BS in Math. But the upper stratosphere of science, the cream of the crop, is so advanced that I will have to go to my grave without having seen what they've seen. The notion of the earth resetting it's entropy clock is silly, Raph.
