2. Was the universe designed, or random?

People tend to take a lot for granted. The sun keeps shining, the earth is full of useful minerals and gravity keeps us from flying off into space. We don’t think about it much, but what if things were different? What if gravity repulsed rather than attracted? What if we couldn’t sit on a chair […]

1. Why does the universe exist?

When thinking about possible evidence for the existence of God, it seems logical to start with the big picture, and work our way down to the more personal. So we start by considering the universe and the explanation of its existence. What is the universe? This may sound like the dumbest of questions, for we […]

Did the universe have a beginning? Did it arise from nothing?

I suppose it is quite natural to look at the night sky, especially away from city lights, and be in awe. When we learn that the universe apparently contains something like 100 billion galaxies, each with about 100 billion stars, our amazement and awe increase. It is also natural to ask where it all came […]

Stereoscopic vision and God

Stereoscopic vision is a useful and subtle aspect of how we, and some animals, see. Because our two eyes both face the front (unlike some animals and insects whose eyes face more left and right), they both see similar but subtly different views. For example, if two objects are in line, one behind the other, […]

Are we alone in the universe?

Contact with aliens is a popular theme in science fiction stories. Some people even think they have seen, or been contacted by, aliens. But so far, despite more than 30 years of a scientific Search for Extra-terrestrial Intelligence (SETI), no evidence has been found that there is any intelligent life “out there”. But some new […]

How strong is the Kalam Cosmological argument?

A friend and I have been discussing the Kalam Cosmological argument recently, so I thought it might be worth posting about it. The Kalam argument has been used many times by philosopher William Lane Craig in public debates, with some success. His use of the argument is itself much debated on the internet. I have […]

Can we trust our intuition? (A question from a reader about the start of the universe)

I am grateful to a reader Mustahsin Mir, who asked me some questions about an argument in the book Atheist Universe: The Thinking Person’s Answer to Christian Fundamentalism by David Mills. I haven’t read the book, but the argument can be followed in Amazon’s Look Inside, with Mustahsin’s questions relating to the section on page […]

Cosmology and God – the latest news

Astronomy, cosmology and especially the origin and “fine-tuning” of the universe have long been of interest to me. So I was interested to hear a recent radio discussion between cosmologists Sean Carroll and Luke Barnes, where they discussed the start of the universe, fine-tuning and God.

Something from nothing?

Nate, who blogs at Finding Truth, and I have been internet friends and opponents for maybe 6 or 7 years. We read each other’s blogs, sometimes comment and occasionally blog in reply to each other. Recently, in response to a question of mine, Nate blogged on the question of whether the beginning of the universe […]

Book review: A Fortunate Universe

I have been waiting for this book for a long time, and while it isn’t perfect, it doesn’t disappoint. The so-called “fine-tuning”note 1 of the universe has been the subject of much scientific investigation and philosophical thought since it became apparent less than 50 years ago. Aussie cosmologist Luke Barnes has written and talked about […]
