“Is the universe a free lunch” by Kevin Rogers

On the 22nd August Kevin Rogers gave a talk on “Is the universe a free lunch?”

It takes a lot of energy to launch a rocket into outer space. Likewise, it seems pretty obvious that it would also take an enormous amount of energy to cause our universe to expand against the force of gravity. However, some cosmologists have claimed that gravitational energy is negative, which cancels out other forms of positive energy (such as heat, light, mass and kinetic energy) such that the total energy of the universe is zero. Thus, no energy is required to create the universe, and our universe is the ultimate free lunch. In “A brief history of time” Stephen Hawking made this claim but provided no justification. In “A universe from nothing”, Lawrence Krauss made the same claim and provided a very brief argument based on Newton’s gravitational equations, but Krauss’s argument looks wrong.

I have spoken to a number of physicists on this issue. A few of them have initially affirmed it, but then are unable to say why. I have never heard a plausible explanation. I have no in principle objection to the free lunch hypothesis. I don’t propose to be dogmatic, and am happy to be shown that I am wrong. If it is true, then it could explain what creation ex nihilo actually means. However, “Is the free lunch hypothesis true and can it be justified?” I will present my argument for why I believe it isn’t and you can judge whether I am wrong.

The Bible: What does “Inspired by God” mean? – by Brian Schroeder

September 8, 2024

On the 8th August Brian Schroeder gave a presentation on on “what does it mean for the Bible to be inspired by God?”

Penn Jillette has said: “I think that anyone who is thinking about maybe being an atheist, if you read the Bible or the Koran or the Torah cover to cover I believe you will emerge from that as an atheist. You could read The God Delusion by Richard Dawkins, you can read God is Not Great by Hitchens, but the Bible itself will turn you atheist faster than anything.”

And yet we frequently find in practice it works out exactly the opposite of that. Many people have picked up this book & read it and heard, as it were, the voice of God speaking directly to them from its pages & have come to God rather than being driven to atheism. They find in its pages hope and truth and life. Christians claim that the Bible is inspired by God. What exactly does that mean, and what are the implications of such a belief?

Brian’s presentation is available on YouTube.

The Miller-Urey experiment, by Joshua Meade

July 29, 2024

On the 25th July Joshua Meade spoke on the Miller-Urey experiment.

Here is Joshua’s summary:

The Miller-Urey Experiment, conducted in 1952, is considered a scientific breakthrough in the field of abiogenesis. Stanley Miller, while under the supervision of Harold Urey, conducted an experiment that simulated what was thought to be early Earth conditions. The famous experiment used a mixture of gases, plus simulated lightning in the form of a spark in order to produce a selection of racemic amino acids. Amino acids are one of the fundamental building blocks required for life.

This worldview sparks debate amongst theists and atheists. I’ll be presenting the perspective from each side and will attempt to give a reasonable representation of the current arguments.

Joshua’s talk is available on YouTube.

A Christian Perspective on the Occult – by Bronwyn Pearse

July 29, 2024

On the 11th July Bronwyn Pearse spoke on a Christian perspective on the occult.

In the Western post Christian era, the 21st century has seen an upsurge in people exploring spiritual experiences. How should the 21st century Christian view Occult practises? Are they harmless, as some argue, or do they really hold potential power?

Does the Bible say anything them? C.S Lewis himself said “We cannot biblically dismiss the reality of external, personal evil forces diametrically opposed to the kingdom of God; ones which actively work against the one who came to bring humans life in all its fullness- mind, body and spirit.”

This talk explores what today’s Occult practices look like and what the Bible says about Ghosts.

Bronwyn’s talk is available on YouTube.

Bronwyn Pearse is a primary school teacher and a Christian. Bronwyn has personally found that apologetics has strengthened her faith and helped her to answer questions from unbelievers on the problem of evil, how Christianity is unique amongst the world religions and how science and faith connect.

The Pentecostal/charismatic movement, by Stephen White

July 29, 2024

On the 27th June, Stephen White spoke on the Pentecostal/charismatic movement.

At the Global Christian Forum in Accra, Ghana, 16-20 April 2024, Dr. Gina Zurlo, co-director of the Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary, pointed to the surprising statistic that today 44% of Protestant Christians reside in Africa:

“The Pentecostal Charismatic Movement, originating in the early 20th century, has become a hallmark of Global South faith, encompassing diverse manifestations within classical Pentecostalism, the Catholic Charismatic Movement, and other charismatic movements. Wherever Christianity spread, and in the 20th century, the Pentecostal charismatic movement spread with it. It appears that the future of global Christianity seems to be Pentecostal.”

The Pentecostal Charismatic movement hails back to the founding of the church on the Jewish Harvest Festival Feast of Weeks, 50 days after Passover (7 weeks or 50 days Pentecostal in Greek) when Jesus died and rose again. From that time many miracles were performed by the Apostles and other members of the church. The first one was speaking the gospel in languages understood by Jews from other parts of the world gathered for the festival.

In St Paul’s first recorded letter to the Corinthian church, about 55AD, he lists the charismatic gifts and places some restrictions on how they should be used in orderly church meetings.

After the completion of the recognized New Testament books recordings of miraculous signs seemed to lapse until just over 100 years ago when they burst out at the Azusa Street revival in Los Angeles in 1906.

Since then, the Pentecostal Charismatic movement has spread widely particularly in Africa and Latin America, as well as in Australia and the USA.

R.T. Kendall, former minister at Westminster Chapel in London, has said that the Word Churches and Spirit Churches have much to learn from each other, and both recent Popes have encouraged their flock to encourage the charismatic movement in the Catholic church.
