    Cosmology in crisis, part one: how to build a universe

    Most of the universe is missing. Only 5% of it is normal matter, which makes up all the people, planets and stars we can see; the other 95% consists of mysterious dark matter and dark energy. Scientists have some hypotheses of what these enigmatic substances might be but recent astronomical observations have posed challenges to their ideas. Even worse, it could mean that there are cracks in the standard model of cosmology, the best scientific description of the universe’s evolution. It’s a nerve-wracking time for cosmologists—is everything they thought they knew about to come crashing down? This is the first of two episodes that explore a looming crisis in cosmology. We examine what scientists understand about the evolution of the universe, and why their best model might be under pressure. Host: Alok Jha, The Economist’s science and technology editor. Contributors: Mark Mcculloch, Michael Brown, Rebecca Bowler and Erik Rosenberg of the University of Manchester; Nathalie Palanque-Delabrouille of DESI and the Lawrence Berkeley National Laboratory.

  • How did two old, unpopular men end up running for the world's most demanding job? It’s the question John Prideaux, The Economist’s US editor, gets asked the most. And the answer lies in the peculiar politics of the baby boomers.  Since 1992, every American president bar one has been a white man born in the 1940s. That run looks likely to span 36 years - not far off the age of the median American. This cohort was born with aces in their pockets. Their parents defeated Nazism and won the cold war. They hit the jobs market at an unmatched period of wealth creation. They have benefitted from giant leaps in technology, and in racial and gender equality.  And yet, their last act in politics sees the two main parties accusing each other of wrecking American democracy. As the boomers near the end of their political journey, John Prideaux, The Economist’s US editor, sets out to make sense of their inheritance and their legacy.  Launching July 2024.
