Are we open to changing our beliefs? What assumptions are we willing to let go of if the evidence suggests otherwise? That openness is at the heart of the scientific process. To be human is to dream and to question. But when do our dreams turn into delusions, and our questions harden into conspiracies?

This episode explores two powerful beliefs—and the increasingly popular movements behind them. One is the belief that humans could, and should, live in space: that we're destined to leave our planet behind and colonize the stars. The other is the belief that we're not on a planet at all—that the Earth is actually… flat. While one is held by fringe figures and the other by some of the most powerful men on the planet, both rest on the premise that humans are exceptional, unbound by limits, or somehow separate from the earth.

To explore these modern myths, we're joined by two guests: astrophysicist Tom Murphy and documentary filmmaker Daniel J. Clark, whose film Behind the Curve follows prominent figures in the fringe—but growing—flat Earth movement. Together, we'll examine the stories we tell ourselves about the world we inhabit, how we determine what's real or possible, and what kind of world these stories create.

28 years after the Rage Virus spread across the UK, the British Isles have been completely quarantined from the rest of the world. Zombies roam the forests and countryside while the survivors huntwith bows and arrows and make do in their fortified village. But for 12-year-old Spike, this is all normal. 28 Years Later is director Danny Boyle's sequel to the classic zombie thriller 28 Days Later.

In this bonus conversation, Jake Marquez and Maren Morgan from the Death and the Garden podcast join me to explore the post-industrial world of 28 Years Later.

Picture the future 100 years from now. What do you imagine? Flying cars? Space colonies? AI talking toasters?

But if we can't sustain an endlessly growing economy - even with a transition to green energy - what does a realistic and positive future look like?

Alex joins the hosts of Crazy Town to imagine life in the 22nd century: walking from our family farms into communal villages, living off the land in a low-energy lifestyle, taming our pet donkeys, and resisting our local warlords.

It's not the future the movies told us to expect. But it might be a future we enjoy living in.
