Is Dark Matter the Wrong Idea?

Without dark matter and dark energy, the equations of physics don’t match what we observe in the cosmos. But what if it’s not the universe that needs extra ingredients—but the equations that need a rewrite? Renowned theorist Erik Verlinde joins Brian Greene to explore his bold reimagining of the laws of nature. This program is part of the Big Ideas series, supported by the John Templeton Foundation.
