The pseudoscientific scale looksmaxxers use to rate each other

If you have teenagers in your life, they’ll probably have heard of the PSL scale. Or at least the language associated with it. Chad. Stacy. Normie. Subhuman. The PSL scale is a pseudoscientific attractiveness rating system used by looksmaxxers, men in a part of the manosphere who can go to extreme methods to change their appearance. The roots of this rating system lie in misogynistic online forums used by incels or involuntarily celibates, but now it’s all over social media. So how did the language of incels, and this one way of quantifying attractiveness and beauty, go so mainstream? In this episode, we speak to Jordan Foster, an associate professor of sociology at MacEwan University in Alberta, Canada, who researches social media, beauty and masculinity. He explains the origins of the PSL scale, where it fits into the manosphere, and how some looksmaxxing influencers are making money off it. This episode was written and produced by Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

Quantum mechanics: does objective reality exist?

It is hard to shake the intuition that there's a real and objective physical world out there. If I see an umbrella on top of a shelf, I assume you do too. And if I don't look at the umbrella, I expect it to remain there as long as nobody steals it. But the theory of quantum mechanics, which governs the micro-world of atoms and particles, threatens this commonsense view. Featuring Chiara Marletto, Research Fellow of Physics, and Christopher Timpson, Professor of Philosophy of Physics, both at the University of Oxford, and Marcus Huber, Professor of Physics, TU Wien. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

Fundamental constants: is the universe fine tuned for life to exist?

Imagine a universe with extremely strong gravity. Stars would be able to form from very little material. They would be smaller than in our universe and live for a much shorter amount of time. But could life evolve there? It after all took human life billions of years to evolve on Earth under the pleasantly warm rays from the Sun. Now imagine a universe with extremely weak gravity. Its matter would struggle to clump together to form stars, planets and – ultimately – living beings. It seems we are pretty lucky to have gravity that is just right for life in our universe. Featuring Fred Adams, professor of physics, University of Michigan, and Paul Davies, professor of physics, Arizona State University. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally? Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Will we ever have a fundamental theory of life and consciousness?

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, we don’t really know yet. Life seems to just somehow emerge from non-living parts. Featuring Jim Al-Khalili, professor of physics at the University of Surrey and Sara Imari Walker professor of physics at Arizona State University. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

What is fair?

Should poorer countries be compensated for climate disasters that aren't their own making? The concept of "loss and damage" was debated at the United Nations COP27 climate summit in Egypt in November 2022 – which resulted in an historic agreement to establish a loss and damage fund to compensate countries that are most vulnerable to the impacts of climate change. In our final episode of Fear & Wonder, we hear from Senegalese meteorologist Aïda Diongue-Niang, who called us from COP27. She explains how African nations are already highly vulnerable to the impacts of climate change. She also takes us inside the gruelling final approval session of the IPCC's Synthesis Report. Her behind-the-scenes account reveals the dedication and determination of the scientists involved. We also hear from Mauritanian public health expert Guéladio Cissé, who details how more intense rainfall is already increasing the risk of water-borne and vector-borne diseases. Finally, we recap what we've learned throughout this podcast. We reflect on how the event that sparked its creation – the Australian Black Summer bushfires of 2019–20 – has inspired survivors to fight for climate action. In case you're new here: Fear & Wonder is a new climate podcast, brought to you by The Conversation. It takes you inside the United Nations’ era-defining climate report via the hearts and minds of the scientists who wrote it. The show is sponsored by the Climate Council, an independent, evidence-based organisation working on climate science, impacts and solutions. ...

Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.
