Dr Luke Barnes talks science, rationality, and the wonders of the night sky.

"We’ve described the way the world works. We haven’t in any way explained why it’s there in the first place."

In this episode, we celebrate National Science Week with Dr Luke Barnes, an astrophysicist with the Sydney Institute of Astronomy.

Join us as we unravel the mysteries of the universe (sort of); find out if stars truly are the great lion kings of the past looking down on us; ask what an orderly world suggests about the possibility of a 'Rational Mind' behind it all – and more.

And he encourages all of us to look into the night sky and take a moment to contemplate the universe.

"I think it’s very good to be reminded of how small we are."
