From the celestial ballet of exploding supernovae to the cosmic whispers of gravitational waves, acclaimed astrophysicist Tamara Davis’ journey through the cosmos promises to captivate and inspire. With over two decades dedicated to unravelling cosmic mysteries, Tamara Davis has played a pivotal role in monumental astronomical surveys, uncovering over half a billion galaxies and illuminating the enigmatic nature of dark energy.

Listen as she shares her groundbreaking research with UNSW's Dean of Science, Sven Rogge, which has revealed that not only is the universe accelerating, but the very essence driving this expansion may be evolving over time.  

Presented by the UNSW Centre for Ideas, Australian Institute of Physics and UNSW Science as a part of National Science Week.

When it comes to climate change, answers can be difficult to nail down. Will the world reach net zero in time? What does a climate change future even look like? Will the changes come in my lifetime – or is it my kids or grandkids who will suffer? With every uncertainty, you can feel your head sink a little deeper into the sand...

What is it about our lives, and the way we do, or don’t, think about climate change, that makes it so difficult to change our behaviors? And what’s being done to help motivate people in high-risk areas to prepare?

The Earth is cracking under the weight of our expectations, with growth held up as the economic north star. Meanwhile, wildlife populations are collapsing, the ocean is acidifying, and carbon emissions are still increasing. Despite everything we know about what’s wrong and what to do about it, we cling to our current way of life.

Civilizations have collapsed before. Could it be happening again? And if it is, what can we be doing to prepare for it?

• Tommy Wiedmann – Professor of Sustainability, UNSW Engineering

As we struggle to reduce carbon emissions, environmental markets are creating a world where money really does grow on trees. But does putting a price on nature, and forcing the economy to value the things it’s always taken for granted, really work? And can it help us prepare for climate change?

In the popular imagination, preppers are busy hoarding tinned food in their bunkers while they wait for the end of the world. But is this what most prepping looks like? And is climate change as bad as all that? 

The bin fire of the last few years has ramped the eco-anxiety up to an 11. But as we go about our lives, studying, feeding our families, paying off our debts and waiting for the next season of The Great British Bake Off, have we all put our heads a little too far into the sand? Sure, we’re all worried, but we can’t be thinking about it all the time, much less heading to the hills to shoot our dinner and drag it back to our underground bunkers. Besides, it won't come to that... will it? 

Is there anything we can learn from the prepping mindset as the reality of climate change comes barrelling toward us?

Intuition isn’t just hippie-dippie or woo-woo – it saves lives, averts disasters and drives countless innovative business decisions. Apple co-founder Steve Jobs, for one, regularly relied on his gut instincts. 

Leading Australian neuroscientist and psychologist Joel Pearson’s The Intuition Toolkit: The New Science of Knowing What, Without Knowing Why presents five scientifically solid strategies for developing intuition that anyone can learn to harness and trust. 

Listen to unlock the mysteries of human consciousness as Joel teaches us when it’s safe to rely on intuition in decision-making.

Humankind stands at a crossroads: will artificial intelligence make us superhumanly productive, liberating us from life’s most mundane tasks? Or have we opened Pandora’s box, unleashing sentient technology that will eventually destroy us? 

In a colossal contest of persuasion and wit, two teams of our best and brightest debate whether artificial intelligence is better than the real thing.  

Listen and help us decide once and for all who wins in the battle of man vs. machine with team captains Annabel Crabb and David Marr, as they duke it out alongside teammates Matilda Boseley, Rhys Nicholson, Tracey Spicer and Toby Walsh.
