What does the end of the universe tell us about the meaning of life?

8 Comments

Details of a recent scientific discovery from the Canberra Times.

Excerpt:

The universe is running out of usable energy and the end is nearer than expected, according to Australian National University astronomers.

[…]PhD student Chas Egan and his supervisor Charley Lineweaver from the ANU Research School of Astronomy and Astrophysics calculated how run-down the universe was and found it was 30 times more dilapidated than previously thought.

In doing so they measured the universe’s entropy a gauge of how ”disorderly” the cosmos is and how close it is to its cold, lifeless end.

[…]Mr Egan said all the processes that occurred in the universe increased its entropy.

”When you leave any isolated system it gets more and more disorderly,” he said.

[…]Scientists believe that end will take the form of a ”heat death”.

”All the matter currently in stars and planets will be spread out homogenously through space and it will be cold and dark and nothing will be able to live and no processes will go on.

More details of the discovery from the Australian newspaper The Age.

Excerpt:

The findings, to be published in the Astrophysical Journal, have implications not just for Earthlings but for any extraterrestrial life as well.

”We’re not just talking about our solar system or our galaxy, we’re talking about our universe,” he said.

”These constraints apply to all life forms that might be in the universe.”

What implications does this discovery have on the question of meaning and purpose in life? If nothing that we do now will survive the end of the universe, then what reason do we have to do anything?

Atheist and Christian responses to the end of the universe

We can get BOTH SIDES of the question from this clip of a formal debate featuring Christian scholar William Lane Craig and atheist writer Christopher Hitchens.

The question being debated is: “Is there objective meaning and purpose in life without God?”. Hitchens and Craig agree that without God, the universe will cool down and all life will die. And they both agree that if there is no God, then there is no objective meaning and purpose in life.

Hitchens says that he can arbitrarily choose a purpose for his life that makes him happy and fulfilled. But notice that this purpose is an arbitrary personal preference. Someone who chooses mass murder or slavery, and has the power to carry it out with impunity, has as much right to choose that purpose as Hitchens does to choose his.

What can we conclude from the atheist view of purpose and meaning?

What does it say about atheism that there is no way to distinguish between William Wilberforce and Josef Stalin? They were both just doing what made them happy, and there is no way either of them ought to have acted, and no objective moral standard by which to praise or condemn them. Some people admire Wilberforce. Some people admire Stalin. No one is right or wrong, because the choice of life purpose is arbitrary, on atheism. So long as you are happy, and the majority of people in your time and place applaud you, anything is permissible.

What would you think of a person whose every action is designed to maximize their pleasurable feelings in this life? What would you make of a person who believed that other people were just bags of atoms, with no human rights and no free will? What would you make of a person who thought that other people were just objects to be used (or dispersed) in whatever way made them feel happiest? What does a selfish attitude do to enterprises like marriage and parenting?

Is it any surprise that we have killed 50 million unborn babies as a result of our own irresponsible search for pleasure? Sex is fun, but taking responsibility for the decision to have sex is not fun. So we kill innocent people who are weaker than us in order to maximize our pleasure in this life. And why not? On atheism, there is no objective meaning in life, no objective purpose to life, and no objective moral standard of right and wrong.

Doug Axe explains the chances of getting a functional protein by chance

3 Comments

I’ve talked about Doug Axe before when I described how to calculate the odds of getting functional proteins by chance.

Let’s calculate the odds of building a protein composed of a functional chain of 100 amino acids, by chance. (Think of a meaningful English sentence built with 100 scrabble letters, held together with glue)

Sub-problems:

  • BONDING: You need 99 peptide bonds between the 100 amino acids. The odds of getting a peptide bond is 50%. The probability of building a chain of one hundred amino acids in which all linkages involve peptide bonds is roughly (1/2)^99 or 1 chance in 10^30.
  • CHIRALITY: You need 100 left-handed amino acids. The odds of getting a left-handed amino acid is 50%. The probability of attaining at random only L–amino acids in a hypothetical peptide chain one hundred amino acids long is (1/2)^100 or again roughly 1 chance in 10^30.
  • SEQUENCE: You need to choose the correct amino acid for each of the 100 links. The odds of getting the right one are 1 in 20. Even if you allow for some variation, the odds of getting a functional sequence is (1/20)^100 or 1 in 10^65.

The final probability of getting a functional protein composed of 100 amino acids is 1 in 10^125. Even if you fill the universe with pre-biotic soup, and react amino acids at Planck time (very fast!) for 14 billion years, you are probably not going to get even 1 such protein. And you need at least 100 of them for minimal life functions, plus DNA and RNA.

Research performed by Doug Axe at Cambridge University, and published in the peer-reviewed Journal of Molecular Biology, has shown that the number of functional amino acid sequences is tiny:

Doug Axe’s research likewise studies genes that it turns out show great evidence of design. Axe studied the sensitivities of protein function to mutations. In these “mutational sensitivity” tests, Dr. Axe mutated certain amino acids in various proteins, or studied the differences between similar proteins, to see how mutations or changes affected their ability to function properly. He found that protein function was highly sensitive to mutation, and that proteins are not very tolerant to changes in their amino acid sequences. In other words, when you mutate, tweak, or change these proteins slightly, they stopped working. In one of his papers, he thus concludes that “functional folds require highly extraordinary sequences,” and that functional protein folds “may be as low as 1 in 10^77.”

The problem of forming DNA by sequencing nucleotides faces similar difficulties. And remember, mutation and selection cannot explain the origin of the first sequence, because mutation and selection require replication, which does not exist until that first living cell is already in place.

But you can’t show that to your friends, you need to send them a video. And I have a video!

A video of Doug Axe explaining the calculation

Here’s a clip from Illustra Media’s new ID DVD “Darwin’s Dilemma”, which features Doug Axe and Stephen Meyer (both with Ph.Ds from Cambridge University).

I hope you all read Brian Auten’s review of Darwin’s Dilemma! It was awesome.

Illustra also made two other great DVDs on intelligent design. The first two DVDs “Unlocking the Mystery of Life” and “The Privileged Planet” are must-buys, but you can watch them on youtube if you want, for free.

Here are the 2 playlists:

I also recommend Coldwater Media’s “Icons of Evolution”. All three of these are on sale from Amazon.com.

Phillip E. Johnson lectures on science and the pre-supposition of materialism

5 Comments

Have you all heard of Phillip E. Johnson, the UC Berkeley professor who is the father of the intelligent design movement?

Here is a lecture by Phil in which he explains the relationship with materialist philosophy and the practice of science.

The MP3 file for lecture is here. There is some Q&A at the end.

Topics:

  • Can the diversity of life be explained by purposeless material processes?
  • What can changes over time have scientists actually observed?
  • What is the difference between micro-evolution and macro-evolution?
  • Has macro-evolution ever been observed?
  • Can observations of micro-evolution be extrapolated to prove unobserved macro-evolution?
  • What causes people to doubt that material processes can account for all of life?
  • Is evolution compatible with Judeo-Christian monotheism?
  • How do scientists respond when you ask them for evidence of macro-evolution?
  • Are observable mutations generally helpful or harmful?
  • How do scientists who pre-suppose materialism deal with dissenting scientists?
  • Why was the theory of Darwinian evolution accepted by early scientists?

Highly recommended. Phil is one of my favorite authors.

The one point you need to take away from this lecture is that if a scientist assumes a philosophy of materialism, then they will never be able to find evidence of intelligent causation in nature. They can look at all the evidence they want, or no evidence at all, and the answer will always be “no-God did it”.

So, consider the Big Bang. No-God did it. The fine-tuning? No-God did it. The origin of life? No-God did it. Molecular machines? No-God did it. Cambrian explosion. No-God did it. Origin of consciousness? No-God did it. Origin of free will? No-God did it. Origin of human rights? No-God did it. Origin of objective morality? No-God did it. Bodily resurrection? No-God did it. Galactic fine-tuning? No-God did it. Planetary fine-tuning? No-God did it. And so on. What else could have done it, once you assume matter is all there is?

The thing to do is to ask them what reasons they have for believing that this pre-supposition of materialism is absolute and undeniable. What is the evidence for it, that does not already assume it?

But many people change their pre-suppositions as evidence piles up that they are wrong. A combined approach is best. Surface their pre-suppositions and make them defend them. Then, stack up evidence against the pre-suppositions, e.g. – how can matter be all there is if science shows us that the entire physical universe came into being out of nothing in the Big Bang?
