Since September we've met 16 scientists, in fields from neuroscience and quantum physics to archaeology and ecology, who are asking wild questions, exploring the world in different ways, wondering what if the world isn't how we thought. They've all been surprising, brilliant and creative in different ways: for me, each chat has been like a glimpse into a fascinating, hidden world.

To finish the season, this week's episode is a bit different. I've asked my lovely producer, Julian Mayers (who also happens to be a cosmologist), to join me for a look back over some of our favourite moments from the interviews, from falling whales and Neolithic virtual reality to improvising ponds and moments of utter bliss...

As we take a pause over Christmas, thanks to all our guests so far and to you for listening. This first season has been successful far beyond our expectations - we've been recommended by publications including New Scientist and Smithsonian, we were featured by Apple as a top new science show, and we've had listeners in more than 80 different countries, from Madagascar to Mongolia to Montenegro.

We'll be back in the new year with season 2, so if you've enjoyed the show do subscribe now so you don't miss that when it comes.

Bye for now! And see you next time on Where the Wild Thoughts Are.

What happens if we let go of our expectations about nature – all the things we think it is, or isn’t, or should be – and just… listen?

Our guide into the unknown this week is award-winning sound artist and ecologist David de la Haye. I first met him at this year’s New Scientist Live in London: I was giving a talk about the science of awe and David came up to me afterwards to tell me about the awe he finds though his work with sound. Essentially he puts hydrophones into the water and records the submerged soundscapes of ponds. He calls it sonic pond dipping.

Rather than dissecting out individual noises or creatures – although that can provide valuable information – David’s work is primarily about listening to an ecosystem in an immersive and very personal way – almost like a meditation. He doesn’t stop at listening, though, he also answers back, creating music – often improvising in real time – with the ponds!

I asked him how he ended up listening underwater, and what he thinks we can learn from these tiny wild spaces that we so often overlook.

People have long told stories about the moon’s power, from werewolves shapeshifting by the moon, to the belief that drinking water soaked with moonlight could help women conceive. And monthly rhythms appear across nature, from corals and cacti to gorillas.

But while there's lots of research showing that the daily cycles of the sun are crucial for biology, scientists have largely ignored the role of the moon – or dismissed it as pseudoscience, particularly in humans. That’s partly because there hasn’t been a convincing mechanism for how the moon might influence life on Earth - which is what my guest this week, Kristin Tessmar-Raible of the University of Vienna, is working to uncover. She studies lunar timing in marine bristleworms: four-eyed, many-legged creatures that swarm according to the phase of the moon and have light receptors buried in their brains.

Forget biological clocks, this is a biological calendar. And the fascinating thing is, she’s uncovering surprising parallels with human biology, which means what’s happening in the worms could help to reveal our own deep connection with the moon, from fertility to sleep to mental health. Jo and Kristin discuss just how far-reaching the moon’s influence may be, the colleagues who once thought she was crazy, and what it takes to change minds in science.

How does using AI change who we are? Last week on Where the Wild Thoughts Are, we talked about freeing AIs to have their own creative ideas and express their own realities. This week we’re flipping that theme, with philosopher Caterina Moruzzi of Edinburgh College of Art, to explore how people and AIs work together, and what that relationship does to us as humans.

There’s evidence that when we use AI chatbots to effortlessly generate pretty much anything we want – an essay, poem, painting – that may erode our own ability to think and create. Even if the end result looks impressive, we engage and learn less. But what if we turn that relationship on its head? Instead of using AIs to generate stuff (so we don’t have to); what if we design them to provoke and stimulate our thinking; to expand the possibilities that we can explore; to inspire us to new artistic heights?

I asked Caterina how we can move beyond simply typing prompts into chatbots, and the conversation took us from pianos and provocateurs to mindfulness and magnetic poetry. What if AIs could make us more engaged, more creative, even more human?

Can an AI have wild thoughts? Are machines capable of true creativity, true art, of going beyond the training and the prompts we give them in order to explore new worlds?

My guest this week is Simon Colton of Queen Mary, University of London. He’s a professor of computational creativity who has been working towards this goal for decades, and he thinks the answer is yes… but only if we give AIs the freedom to choose what they create and to use their own experiences as inspiration.

It’s an interesting approach that invites us to think about AI from the inside. Whether or not you reckon an AI can be conscious, AIs do have interactions every day – so many of them – and what you could think of as experiences that they could perhaps express in a poem or a painting.

Simon and I discuss how to develop truly creative AIs – including projects of his such as the Painting Fool and the What If machine – as well as what the inner world of an AI might be like. What would it express, if it was able to do that through art?

Thinkers don’t come much wilder than Albert Einstein. His out-of-the-box physics transformed how we think about the universe: with his famous equation E=mc2 he showed that energy and matter are one and the same; through his theory of relativity he joined space and time into one malleable fabric that can morph according to your point of view.

But we’re talking about a very different side to Einstein. My guest is Kieran Fox, a physician and neuroscientist at the University of California, San Francisco, all-round spiritual explorer, and author of a fascinating book called I am a Part of Infinity. Kieran argues that Einstein didn’t confine his revolutionary thoughts to the physical world. The physicist was also deeply spiritual: he followed what he called a “cosmic religion”, that he hoped would unify science and religion; mind and matter; us and the cosmos.

Biographers and historians have tended to skate over this aspect of Einstein’s life… maybe they felt it wasn’t a suitably rational topic for such a hero of physics. But Kieran has pieced together Einstein’s religious thinking and traced influences from Pythagoras and Spinoza to the Tao Te Ching. He argues that Einstein’s spirituality wasn’t a minor sideshow, and it didn’t just co-exist with his physics, it was central, his ultimate motivation for wanting to understand the nature of reality in the first place.

What was this sacred path - and is it still relevant today? I asked Kieran to tell me all about it.

Standing waves and resonant frequencies appear everywhere in the world around us, from musical notes and swaying bridges to electron orbits and animal coats. This week's guest, neuroscientist Selen Atasoy, wondered if they could also be found in the brain.

Her work has led to a new way to understand different states of consciousness -- from anaesthesia through our normal waking state to meditation and psychedelics. She explains how changes in our awareness reflect a shifting balance between order and chaos, and why psychedelics may tune the brain closer to a critical point of maximum complexity.

I talk to Selen about what this all means for our understanding of the mind, including how modern life may be blunting our awareness, and whether consciousness might be possible elsewhere in the natural world, beyond the human brain.

This isn’t the end of Selen’s story, though, as she recently trained as a psychotherapist. We discuss what inspired her leap from objective science towards a more personal exploration of the mind, and how we can all find harmony within.

Steady your nerves and light up your torches, because this week we’re clambering into the deep, dark Neolithic underworld with archaeologist Jens Notroff.

Jens, of the German Archaeological Institute, has spent years excavating one of the world’s most fascinating and mysterious prehistoric sites – Göbekli Tepe in southeastern Turkey. This is a series of circular stone enclosures, featuring giant T-shaped figures and carvings of fearsome predators – and possibly also once decorated with human skulls. It’s sometimes described as “the world’s first temple”, and according to conventional thinking, it shouldn’t exist.

That’s because Göbekli Tepe is around 12,000 years old. It was built on the cusp of the most important transition in human history, the Neolithic revolution, just as hunter gatherers were about to start cultivating the species around them, and it’s located in just the region where farming was about to emerge. Before historians realised the significance of Göbekli Tepe, they assumed the invention of agriculture was the flashpoint that led to the other changes of the Neolithic, such as more settled communities, and the ability to build impressive monuments like Stonehenge. But the giant stones of Göbekli Tepe, dating to just before all of that, tell us something else – a dramatic, shocking shift in mindset – was already underway.

With Jens as our guide, let’s travel back 12,000 years. What wild rituals played out at this deathly site? How did humans take that first leap in thinking, that has defined our species perhaps more than any other, of separating ourselves from – and elevating ourselves above – the rest of nature. And how does it feel to put ourselves into the mind of a young hunter, entering these terrifying caverns for the first time…
