I’ll be speaking at University Of Technology, Sydney on Monday 16th April, 2018. This event was originally pitched to me as another talk about the book, but has since evolved into a four-person discussion/debate event with Prof Peter Slezak (UNSW), Ian Bryce, and Mike Paget.

You may be familiar with Prof Slezak from his very interesting debates with Dr William Lane Craig, which I’ll put below. So I’m hopeful for an entertaining evening.

Time: April 16, Monday 6.30-8.30pm
Location: Aerial Function Centre @ Building 10, Level 7

This is a ticketed event – $10. I have no idea why. Book your tickets at Eventbrite.

I’m in the final stages of moving to a new position at Western Sydney University, so prepare for some more blogging soon about new and important things!

In the meantime, I’ll be speaking in Sydney tomorrow (Monday 19th March, 2018) at the Macarthur Astronomical Society.

Title: The Universe and Entropy, or The top 10 things to do before the heat death of the universe.
Time: Monday 19th March, 2018 at 7:30pm
Location: The small lecture theatre in Building 30 (School of Medicine) at Western Sydney University, Campbelltown Campus.

For the last 13.7 billion years, a variety of complex structures have assembled in the universe we see around us: nebulae, stars, planets, galaxies and more. But the infamous “second law of thermodynamics” says that the universe is winding down, moving from order to chaos.

How do these ideas fit together? Is the story of the universe order from chaos, or chaos from order?

The audiobook of “A Fortunate Universe: Life in a Finely Tuned Cosmos” has arrived!!!


It will be out on a few other platforms soon, we’re told by the distributor. We have absolutely no control over the price, by the way. It took an awfully long time to record and edit, but if you want to hear “A Fortunate Universe: Life in a Finely Tuned Cosmos” read in a charming Welsh accent, you’re in luck!

A note for any would-be audiobook producers: the YouTube channel Booth Junkie is your new best friend. Mike DelGaudio‘s tips for recording and producing, in particular the setup of Reaper, compression, EQ, gates and such, are priceless.

I’ve recently had my first philosophy paper published! It appears in the European Journal for Philosophy of Science, and is available online for free here (I think – tell me in the comments if it doesn’t work). [Edit: It doesn’t. Here’s the preprint.] Here’s the abstract:

Fine-tuning in physics and cosmology is often used as evidence that a theory is incomplete. For example, the parameters of the standard model of particle physics are “unnaturally” small (in various technical senses), which has driven much of the search for physics beyond the standard model. Of particular interest is the fine-tuning of the universe for life, which suggests that our universe’s ability to create physical life forms is improbable and in need of explanation, perhaps by a multiverse. This claim has been challenged on the grounds that the relevant probability measure cannot be justified because it cannot be normalized, and so small probabilities cannot be inferred. We show how fine-tuning can be formulated within the context of Bayesian theory testing (or model selection) in the physical sciences. The normalizability problem is seen to be a general problem for testing any theory with free parameters, and not a unique problem for fine-tuning. Physical theories in fact avoid such problems in one of two ways. Dimensional parameters are bounded by the Planck scale, avoiding troublesome infinities, and we are not compelled to assume that dimensionless parameters are distributed uniformly, which avoids non-normalizability.

Geraint Lewis and I are off to the United Kingdom in October 2017 for a series of blockbuster events! Come and see our double act!

This isn’t my usual topic on this blog, and I’ll get back to some science shortly, but I’ve got something on my mind.

For me, a good movie is one that I’m still thinking about long after I see it. I’m still trying to work out Eternal Sunshine of the Spotless Mind – I’ve even read a philosophy book on it. Well, it’s been a month and I’m still find myself thinking about Whiplash. I need to debrief, so if you haven’t seen it, go watch it on Netflix now. There will be spoilers from here on.

Whiplash tells the story of a young jazz drummer, Andrew Neiman (Miles Teller), who is studying at the prestigious Shaffer Conservatory in New York. Despite being a first year, he is chosen for the big band of Terence Fletcher (J.K. Simmons). Fletcher is a highly respected tyrant who controls his students with fear and intimidation. Neiman initially jumps through Fletcher’s hoops, but the two eventually clash.

In his commentary on the film in The New Yorker, Richard Brody calls the movie’s “very idea of jazz is a grotesque and ludicrous caricature. … [Neiman’s] life is about pure competitive ambition—the concert band and the exposure it provides—and nothing else. The movie has no music in its soul … “Whiplash” honors neither jazz nor cinema.”

I would like to offer the theory that the movie is not supposed to honour jazz, and the lack of music in its soul is no accident. That’s the point. Brody is close to the mark when he says that “the movie isn’t “about” jazz; it’s “about” abuse of power.” Here’s my case. Continue Reading »

I’ll be speaking around Sydney and Canberra over the next few weeks, so come along and hear about all things astronomy and the universe!

Penrith Observatory – Saturday, 6 May

Time: 7.00pm – 9.00pm
Address: Western Sydney University, Penrith Campus, Great Western Highway, Werrington North. Instructions here. Map.

Topic: The Fine-Tuning of the Universe for Life
If we change the laws of nature just a little bit, our universe would be very different to what we have now. After explaining the science of what happens when you change the way our universe works, we will ask: what does all this mean?
Includes presentation, short 3D movie, tour of the dome area and viewing of the night sky through a range of telescopes (weather permitting).

Mount Stromlo Public Astronomy Night – Thursday, 18 August (with Geraint)

Time: 7pm
Address: Mt Stromlo Observatory Visitor Centre, Cotter Road Weston Creek, ACT. Map.
Cost: Gold coin donation. Booking is essential.
More details: here.
Topic: Mount Stromlo Observatory in conjunction with the Canberra Astronomical Society invite the Canberra community to attend our public observing nights of 2017. Come and see the rings of Saturn, the craters of the moon as well as beautiful star clusters and nebulae. On the night attendees will be taken on a ‘tour of the universe’ with talks by astronomers from Mt. Stromlo Observatory and observations on several telescopes.

Geraint Lewis is a Professor of Astrophysics, a cosmologist who studies dark matter, dark energy, and the evolution of the universe. Luke Barnes is a Postdoctoral Researcher who studies galaxy formation and the fine-tuning of the universe for life. They are authors of “A Fortunate Universe: Life in a finely tuned cosmos”, and work at the University of Sydney’s School of Physics.

Warm clothing is recommended. Southern Cross Stromlo will also be open to serve cold and warm drinks, snacks, and hot soup and roll. In the event of cloudy/bad weather, star gazing will be cancelled and the cafe may be closed (the talks will occur regardless of the weather). You can check out the weather at Mt Stromlo using our all sky camera.
