The kalam cosmological argument explained in a 4-minute video

3 Comments

Here’s the 4-minute video that I would like everyone to tweet and share on Facebook:

It does go over the scientific evidence that has emerged recently that caused scientists to accept the beginning of the universe.

Here’s a re-cap of the three main evidences for the Big Bang cosmology from Caltech.

Excerpt:

What is the Big Bang?

According to the big bang theory, the universe began by expanding from an infinitesimal volume with extremely high density and temperature. The universe was initially significantly smaller than even a pore on your skin. With the big bang, the fabric of space itself began expanding like the surface of an inflating balloon – matter simply rode along the stretching space like dust on the balloon’s surface. The big bang is not like an explosion of matter in otherwise empty space; rather, space itself began with the big bang and carried matter with it as it expanded. Physicists think that even time began with the big bang. Today, just about every scientist believes in the big bang model. The evidence is overwhelming enough that in 1951, the Catholic Church officially pronounced the big bang model to be in accordance with the Bible.

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 theorythat 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.

Why Do We Think the Big Bang Happened?

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.”

The article goes into detail about each of these three evidences.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by atheist Scriptures.

This is a bad time to be an atheist, given the state of science. It was easier to be an atheist before we made these scientific discoveries, but given the progress of science it’s not rational to be an atheist anymore.

William Lane Craig lectures on naturalistic alternatives to the Big Bang

3 Comments

Here’s the lecture, which was given in 2004 at the University of Colorado, Boulder. A very liberal university!

This lecture is suitable for intermediate and advanced Christian apologists.

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 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?

This lecture 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.

The whole research paper that the lecture is based on is posted online.

Do atheists and agnostics have a burden of proof to bear?

2 Comments

My friend William B. shared this Enlightenment Journal post, written by philosopher Paul Copan.

Excerpt:

In conversations with atheists, they may challenge us: “You’re claiming that God exists. Therefore, the burden of proof rests on you, not me. So … where’s your evidence?”

Atheist Michael Scriven insists “we need not have a proof that God does not exist in order to justify atheism. Atheism is obligatory in the absence of any evidence for God’s existence.”1 Or perhaps someone has told you that belief in God is just like belief in Santa Claus or the tooth fairy. Where do we begin to respond to such assertions?

Here is his list of advice:

  1. define your terms — especially atheism
  2. the atheist also bears the burden of proof in making the claim, “God does not exist.”
  3. look out for the “atheist’s” slide into agnosticism, from claiming disbelief to mere unbelief.
  4. distinguish between the two types of agnostics — ordinary and ornery.
  5. distinguish between “proof” and “good reasons.”
  6. we have good reasons for belief in the biblical God, but not in mythical beings like mermaids, elves, unicorns, the tooth fairy, or flying spaghetti monsters.
  7. we should distinguish between two types of ignorance — innocence and culpable — and the agnostic would be quite culpable of refusing to seek.

I want to say something about #7, so here’s the detail on that one:

Seventh, we should distinguish between two types of ignorance — innocence and culpable — and the agnostic would be quite culpable of refusing to seek.When a Western tourist travels to Cambodia, she might not be aware that exposing the sole of her foot or bottom of her shoe is insulting and offensive. The tourist may offend someone out of ignorance of this cultural taboo. But this ignorance is innocent.

There’s another kind of ignorance. What if you are driving down a highway and not paying attention to speed limit signs? An officer may stop you and ask why you were speeding. You cannot rightly say, “I didn’t know what the speed limit was — or even how fast I was going. So you shouldn’t give me a ticket.” Obviously, if you are driving, you are responsible for paying attention. Ignorance is no excuse. It is blameworthy rather than innocent.

Likewise, to say “I do not know if God exists” may reveal a failure in my responsibility to seek God (“I do not wantto know”). In this case, I would be at fault. The Christian Geneticist Francis Collins of Human Genome Project fame said he was an agnostic in college. Yet he confesses that his “I don’t know” was more an “I don’t want to know” attitude — a “willful blindness.”11 This agnosticism eventually gave way to outright atheism — although Collins would later come to faith in Christ. He began reading C.S. Lewis’ Mere Christianity, and Collins realized his own antireligious constructs were “those of a schoolboy.”12

Because the existence of God is a massively important topic, we cannot afford not to pay attention — especially in an age of so many diversions. Philosopher Tom Morris points out that sports, TV, restaurants, concerts, cars, billiards, and a thousand other activities can divert us from the ultimate issues of life. As a result, we don’t “tune into” God. And when a crisis hits (death, hospitalization, natural disaster), we are not really in the best condition to process and make accurate judgments about those deep questions.13 The person who says, “I do not know if God exists,” may have chosen to live by diversions and distractions and thus to ignore God. This is not an innocent ignorance; this ignorance is the result of our neglecting our duty.

So the theist, atheist, and militant (ornery) agnostic all bear a burden of proof; the theist does not have a heavier burden since all claim to know something. Furthermore, even the alleged ordinary agnostic still is not off the hook. For one thing, one cannot remain neutral all his life; he will make commitments or hold beliefs all along the way that reflect either an atheistic or theistic worldview. He is either going to be a practical atheist or practical theist (or a mixture of the two) in some fashion throughout his life. But he can’t straddle the fence for long. Also, the ordinary agnostic may say, “I do not know,” but this often means “I do not care” — the view of an “apatheist.” Refusing to seek out whether God exists or not; refusing to humble oneself to seek whatever light about God is available; living a life of distractions rather than thoughtfully reflecting about one’s meaning, purpose, or destiny leaves one culpable in his ignorance, not innocent.

I had have conversations with people who were not believers, who often tell me flat out that they don’t know whether God exists, or what he is like, but that they live their lives as if he doesn’t exist, and they are not investigating whether they are right. They are very happy operating without any God looking over their shoulder. And God is OK with that, because he doesn’t want to force people who don’t want him into an eternal afterlife with him. He is seeking after and drawing people who will respond to him.

It’s very important to ask questions of atheists and agnostics that will surface this often hidden desire to live life without God. Often, you can get people to show some interest in God’s existence and who Jesus was just by letting them put into words their own decision to avoid God and not investigate God. That is an opportunity for the Holy Spirit to step in. It’s not that you have to be mean, it’s just a good idea to ask questions and then don’t jump on them when they confess. Letting them get the words out there is all you need to do.

Here’s my previous post on whether atheism means a lack of belief in God.
