What is behind a black hole? What do they look like? And how on Earth do you take a picture of one?

In today’s episode, Jara faces one of her childhood fears, namely being sucked into the darkest mystery of the universe – the black hole. How likely is Earth to disappear behind the universe’s final curtain? What would that mean? And what actually is this dreaded black hole, to begin with? Luckily, her guest Heino Falcke has the answers.

Heino is a Professor of Astroparticle Physics and Radio Astronomy at the Institute for Mathematics, Astronomy, and Particle Physics (IMAPP) of the Faculty of Science. Together with his team, Heino was the first one to take a picture of a black hole.

AI seems to have come to stay, but what does the future of artificial intelligence hold? And why is it perhaps one of the most penetrating technologies since the development of language?

In the second part of the AI special, we take a look at the future of AI. Together with Pim Haselager, Antonia talks about how AI might change as a technology – and how humans will likely too. Will reading lose its importance? Can (and should) you generate ideas with the help of artificial intelligence? And how is AI changing the relationship we have to ourselves?

Pim Haselager is a professor of artificial intelligence and a principal investigator at the Donder’s Institute for Brain, Cognition and Behaviour.

This episode is part of a two-part special on Artificial Intelligence. Make sure to also have a look at the first episode of the series about the past and present of AI – and the next Vox magazine on Artificial Intelligence, featuring an interview with Pim Haselager.

How do you persuade an audience? What is ethos, and why is it so important? And what connects ancient philosophers like Aristotle with modern politicians like Donald Trump?

Rhetoric is the answer — at least to many of the questions that arise when taking a closer look at the workings of public discourse. Invented in antiquity, rhetoric still shapes our present and future, and is therefore placed in the spotlight in this episode of In a Nutshell.

Together with her guest Bé Breij, Jara explores the power of rhetoric, its somewhat negative reputation, and how one can analyze the art of persuasion.

Bé is a professor of Latin language and literature, a specialist in ancient rhetoric, and the founder of Peitho, the Radboud knowledge center for rhetoric and persuasion.
