This week on On The Line, Jen Gerson sits down with Philip Ball, one of the world’s most respected science writers, for a wide-ranging conversation about the state of modern science and the art of explaining it. Ball reflects on his journey from laboratory scientist to science communicator, and what it means to challenge old assumptions about the world around us.

Gerson and Ball talk about how the science many of us learned in high school is being reconsidered — from the Big Bang to the origins of life — and how even the most fundamental ideas are far less settled than they once seemed. Along the way, the discussion touches on the mysteries of consciousness, the shifting relationship between science and culture, the role of critics in keeping the field honest, and the challenge of making complicated ideas understandable without losing their meaning.

It’s an engaging conversation about curiosity, humility, and why the pursuit of knowledge never really ends.

In this week's episode of The Line Podcast, recorded on Sept. 19, 2025, Matt Gurney and Jen Gerson open with Canadian federal politics. Mark Carney is clearly cleaning house. We talk about why Chrystia Freeland may actually be entering her best years as a political force, share a laugh about our backstory with Canada’s new ambassador to the UN, and ask whether Carney will use by-elections or the Senate to get his people in.

They then turn south, where the fallout of the Charlie Kirk assassination lingers. Jen has some tough words for people you’d normally think of as her allies, and Matt lays out the conditions under which he’ll take anyone’s views on these matters seriously. They also touch on the Jimmy Kimmel situation.

This episode of The Line Podcast is also brought to you by Forestry For The Future. Canadian forestry supports 200,000 workers, generates $87 billion in annual revenue, contributes $21 billion annually to our nation's economy, and provides the products we need to build homes and drive economic growth. While trade barriers from the U.S. are siphoning jobs and investment away, Canada’s own approval processes and regulations are preventing critical projects that both prevent wildfires and boost our economic self-reliance.

We can and should have programs that expand domestic wood use, advance biomass use and pulp market opportunities, and cut red tape and regulatory barriers. The government of Canada has a clear opportunity to stand up for Canadian forestry at a time of growing global uncertainty. We need real action that puts Canadians first — supporting employees and their families, securing stability for our businesses, and protecting the long-term potential of our sector and its people.

Finally, Matt turns the tables and asks Jen about her recent trips to other spiritual realms. If you’ve read her piece on her visit to the Monroe Institute, this segment will make sense — and if you enjoyed that article, you’ll get some extra value from hearing her describe it in her own words.

This week on On the Line, Matt is joined by two familiar voices. First up, P.J. Fournier from 338Canada.com and 338Canada.ca drops in with a quick update. He’s been tracking the polls as Parliament gets back to work, and his verdict is that not much has shifted since the election. Still, he lays out the opportunities and headaches facing Mark Carney and the Liberals, Pierre Poilievre and the Conservatives, and what's left of the NDP as it tries to figure out what exactly it wants to be ... and what leader will help get them there.

After that, Matt is joined by a friend of the show, Jamie Carroll of Carroll & Co. Consulting. You’ll remember him from our anti-panel during the campaign, and this time he sticks around for a longer chat about what’s happening inside Liberal circles. Why is the caucus already grumbling? What’s keeping Mark Carney awake at night? And why does poor Michael Sabia seem to have been left with a to-do list that might as well include stopping a Russian offensive in eastern Europe all by himself?

We’re (mostly) joking about that last part, but it’s fair to say it’s been a strange few weeks, hasn't it?
