William Lane Craig lectures on naturalistic alternatives to the Big Bang

Leave a comment

Here’s the lecture, which was given in 2004 at the University of Colorado, Boulder.

This lecture might be a little advanced for beginners, but if you stretch your mind first, you shouldn’t tear anything. (Note: standard disclaimers apply if you do tear something!)

The description of the video states:

This is quite simply one of the best lectures William Lane Craig (a philosopher of science) has given. Craig explores the origins of the universe. He argues for a beginning of the universe, while refuting scientific models like the Steady State Theory, the Oscillating Theory, Quantum Vacuum Fluctuation Model, Chaotic Inflationary Theory, Quantum Gravity Theory, String Theory, M-Theory and Cyclic Ekpyrotic Theory.

And here is the description of the lecture from Reasonable Faith:

A Templeton Foundation lecture at the University of Colorado, Boulder, laying out the case from contemporary cosmology for the beginning of the universe and its theological implications. Includes a lengthy Q & A period which features previous critics and debate opponents of Dr. Craig who were in attendance, including Michael Tooley, Victor Stenger, and Arnold Guminski.

Craig has previously debated famous atheists Stenger and Tooley previously. And they both asked him questions in the Q&A time of this lecture. Imagine – having laid out your entire case to two people who have debated you before and who know your arguments well. What did they ask Craig, and how did he respond?

The scientific evidence

The Big Bang cosmology that Dr. Craig presents is the standard model for how the universe came into being. It is a theory based on six lines of experimental evidence.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

If you are looking for some detail on these evidences, here’s a re-cap of the three main evidences for the Big Bang cosmology from Caltech. (Numbers 2, 3 and 5 from the list above)

Excerpt:

Until the early 1900s, most people had assumed that the universe was fixed in size. New possibilities opened up in 1915, when Einstein formulated his famous general relativity theory that describes the nature of space, time, and gravity. This theory allows for expansion or contraction of the fabric of space. In 1917, astronomer Willem de Sitter applied this theory to the entire universe and boldly went on to show that the universe could be expanding. Aleksandr Friedmann, a mathematician, reached the same conclusion in a more general way in 1922, as did Georges Lemaître, a cosmologist and a Jesuit, in 1927. This step was revolutionary since the accepted view at the time was that the universe was static in size. Tracing back this expanding universe, Lemaître imagined all matter initially contained in a tiny universe and then exploding. These thoughts introduced amazing new possibilities for the universe, but were independent of observation at that time.

[…]Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

It’s probably a good idea to be familiar with these if you are presenting this argument, because experimental science is a reliable way of knowing about reality.

Published research paper

This lecture by Dr. Craig is based on a research paper published in an astrophysics journal, and was delivered to an audience of students and faculty, including atheist physicist Victor Stenger and prominent atheist philosopher Michael Tooley, at the University of Colorado at Boulder.

Here’s the peer-reviewed article that the lecture is based on.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

Stephen C. Meyer: does the Big Bang cosmology support the existence of God?

1 Comment

Here’s the 66-minute video featuring Dr. Stephen C. Meyer, who holds the Ph.D in philosophy of science from Cambridge University, and other degrees in the hard sciences.

The lecture starts really, really slowly. You can just fast-forward to the 12 minute mark, or you might die of boredom.

Topics:

  • Up until the the last 100 years or so, everyone agreed that the universe was eternal
  • This is at odds with the traditional Christian view that God created the universe
  • Materialism, the view that matter is all there is, requires eternally existing matter
  • Discovery #1: Hubble discovers that the universe is expanding (redshift observation)
  • The expanding universe was resisted by proponents of the eternal universe, like Einstein
  • Some naturalists even proposed speculative static models like the steady-state model
  • However, not of the speculative models fit with observations and experimental results
  • Discovery #2: Penzias and Wilson discover the cosmic microwave background radiation
  • Measurements of this background radiation confirmed a prediction of the Big Bang theory
  • The steady-state theory was falsified of by the discovery of this background radiation
  • The oscillating model was proposed to prevent the need for an absolute beginning
  • But the oscillating model is not eternal, it loses energy on each “bounce”
  • A paper by Alan Guth and Marc Sher from 1982 proved that our universe will not bounce
  • In addition, experiments reveal that the universe will expand forever, and not contract
  • The beginning of the universe is more at home in a theistic worldview than an atheistic one
  • The beginning of the universe fits in well with the Bible, e.g. – Genesis 1, Titus 1, etc.

In case you are wondering about what the evidence is for the Big Bang, here are 3 of the evidences that are most commonly offered:

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

By the way, Dr. Meyer also does a great job of explaining the problem of proteins, DNA and the origin of life in this lecture. And you can hear him defend his views in this debate podcast with Keith Fox and in this debate podcast with Peter Atkins. He does a great job in these debates.

The Wintery Knight’s favorite Bible verses

14 Comments

I was asked by the Dina to post Bible verses for a week on my Facebook page, so I chose 8 of them.

If you haven’t seen me posting them this week on my Facebook page, here they are:

Psalm 27:14:

11 Teach me Your way, O Lord,
And lead me in a level path
Because of my foes.
12 Do not deliver me over to the desire of my adversaries,
For false witnesses have risen against me,
And such as breathe out violence.
13 I would have despaired unless I had believed that I would see the goodness of the Lord
In the land of the living.
14 Wait for the Lord;
Be strong and let your heart take courage;
Yes, wait for the Lord.

1 Corinthians 4:2:

1 This is how one should regard us, as servants of Christ and stewards of the mysteries of God.

2 Moreover, it is required of stewards that they be found faithful.

3 But with me it is a very small thing that I should be judged by you or by any human court. In fact, I do not even judge myself.

4 For I am not aware of anything against myself, but I am not thereby acquitted. It is the Lord who judges me.

Matthew 5:13:

10 “Blessed are those who have been persecuted for the sake of righteousness, for theirs is the kingdom of heaven.

11 “Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me. 12 Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you.

13 “You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.

14 “You are the light of the world. A city set on a hill cannot be hidden;

15 nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house.

2 Timothy 2:4:

1 You therefore, my son, be strong in the grace that is in Christ Jesus.

2 The things which you have heard from me in the presence of many witnesses,entrust these to faithful men who will be able to teach others also.

3 Suffer hardship with me, as a good soldier of Christ Jesus.

4 No soldier in active service entangles himself in the affairs of everyday life, so that he may please the one who enlisted him as a soldier.

5 Also if anyone competes as an athlete, he does not win the prize unless he competes according to the rules.

Daniel 3:18:

13 Then Nebuchadnezzar in rage and anger gave orders to bring Shadrach, Meshach and Abed-nego; then these men were brought before the king.

14 Nebuchadnezzar responded and said to them, “Is it true, Shadrach, Meshach and Abed-nego, that you do not serve my gods or worship the golden image that I have set up?

15 Now if you are ready, at the moment you hear the sound of the horn, flute, lyre, trigon, psaltery and bagpipe and all kinds of music, to fall down and worship the image that I have made, very well. But if you do not worship, you will immediately be cast into the midst of a furnace of blazing fire; and what god is there who can deliver you out of my hands?”

16 Shadrach, Meshach and Abed-nego replied to the king, “O Nebuchadnezzar, we do not need to give you an answer concerning this matter.

17 If it be so, our God whom we serve is able to deliver us from the furnace of blazing fire;and He will deliver us out of your hand, O king.

18 But even if He does not,let it be known to you, O king, that we are not going to serve your gods or worship the golden image that you have set up.”

Esther 4:14:

10 Then Esther spoke to Hathach and ordered him to reply to Mordecai:

11 “All the king’s servants and the people of the king’s provinces know that for any man or woman who comes to the king to the inner court who is not summoned, he has but one law, that he be put to death, unless the king holds out to him the golden scepter so that he may live. And I have not been summoned to come to the king for these thirty days.”

12 They related Esther’s words to Mordecai.

13 Then Mordecai told them to reply to Esther, “Do not imagine that you in the king’s palace can escape any more than all the Jews.

14 For if you remain silent at this time, relief and deliverance will arise for the Jews from another place and you and your father’s house will perish. And who knows whether you have not attained royalty for such a time as this?”

Philippians 1:9:

3 I thank my God in all my remembrance of you,

4 always offering prayer with joy in my every prayer for you all,

5 in view of your participation in the gospel from the first day until now.

6 For I am confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus.

7 For it is only right for me to feel this way about you all, because I have you in my heart, since both in my imprisonment and in the defense and confirmation of the gospel, you all are partakers of grace with me.

8 For God is my witness, how I long for you all with the affection of Christ Jesus.

9 And this I pray, that your love may abound still more and more in real knowledge and all discernment,

10 so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ;

11 having been filled with the fruit of righteousness which comes through Jesus Christ, to the glory and praise of God.

Numbers 13:30:

25 When they returned from spying out the land, at the end of forty days,

26 they proceeded to come to Moses and Aaron and to all the congregation of the sons of Israel in the wilderness of Paran, at Kadesh; and they brought back word to them and to all the congregation and showed them the fruit of the land.

27 Thus they told him, and said, “We went in to the land where you sent us; and it certainly does flow with milk and honey, and this is its fruit.

28 Nevertheless, the people who live in the land are strong, and the cities are fortified and very large; and moreover, we saw the descendants of Anak there.

29 Amalek is living in the land of the Negev and the Hittites and the Jebusites and the Amorites are living in the hill country, and the Canaanites are living by the sea and by the side of the Jordan.”

30 Then Caleb quieted the people before Moses and said, “We should by all means go up and take possession of it, for we will surely overcome it.”
