Taylor Swift reaches new heights with her latest album, which is both divisive and record-breaking. And it’s fueled by an elaborate series of business choices that propel profits but also chart numbers. Today’s episode comes from our friends at Today Explained, Vox’s lively, smart daily news podcast.
This episode was hosted by Noel King. It was produced by Ariana Aspuru, edited by Amina Al-Sadi, fact-checked by Laura Bullard, and engineered by Adriene Lilly.
Black Friday is finally here and this one-day holiday has somehow become a month-long event. But it’s a reminder that retailers have to play a new game and that’s driving the winners and losers in retail. Plus, we discuss the stocks we would give as gifts and what’s on our radar this week.

When listener Sakura’s husband came home from his morning walk in Cambridgeshire, UK, he told her about a massive rainbow he’d seen. But when he showed her a picture, she didn’t think it was particularly large. So how big is a rainbow really? Are they always the same size? And if some are bigger than others, is there a limit?
To find the answers, presenter Marnie Chesterton meets independent rainbow expert Philip Laven in a pitch-black studio to simulate how a rainbow is formed. He demonstrates how they are created by sunlight, reflecting and refracting in millions of little water droplets.
But what does that mean for their size? Raymond Lee, retired professor from the US Naval academy, says that rainbows are not objects and don’t have a linear size, just a specific angular size that’s relative to the person seeing it. But Marnie doesn’t give up so easily – some rainbows still look bigger than others.
In her journey to discover other ways to size up a rainbow, Marnie hears from Australian aerial photographer Colin Leonhardt who stunned the world with a beautiful picture. Next, assistant professor Ping Wah Li from The Chinese University of Hong Kong explains why it’s possible to come across more than one rainbow at a time.
And finally, atmospheric scientist Harald Edens shares another way to consider size, as well as how much he struggles to explain the complexity of rainbows to his four-year old daughter.

Americans were already losing touch with basic decency before Trump came along—and he exploited that indecency, distrust, and division to win power. In his new novel, George Packer spins a story of an imaginary country that just collapses, and how ordinary people have to learn to live together again. Fiction has a way of making the real world more clear. Plus, Charlie Kirk’s influence on our political climate before his death, JD’s phoniness and lust for power, Trump may be flailing but he’s still amassed immense power, and how AI moving us away from the written word threatens our democracy.

In this encore episode we look at the decision to have children. Much of the attention on the world's plunging birth rate is on east Asian countries like Japan and South Korea. But Latin American countries, like Chile, are also seeing a decline in fertility. We go to Chile’s capital to understand the personal decisions behind the countries plummeting birth rate trend.
The authorities in Hong Kong say fire alarms weren't working properly in the tower blocks where a blaze killed more than 100 people. The buildings were being renovated, and police say they've found materials that are believed not to be fireproof. Also: rescue services tackling heavy floods in South East Asia say they're struggling to cope as roads and communication infrastructure have been severely damaged; how 70 species of sharks and rays are to receive better international protection; and a stand-off between three nuns and their convent in Austria may have reached a resolution.
