Renowned astrophysicist and educator Alex Filippenko joins Brian Greene to discuss an increasingly disturbing cosmological mismatch known as the Hubble Tension, a gap that may require a radical rewriting of …

Often viewed as “spooky” or downright bizarre, quantum mechanics is fueling a powerful new era of amazing technology. In this program, today’s top quantum physicists discuss the information shake-up underway—and predict when we can expect a quantum computer of our own.

As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Which raises a question familiar to aficionados of The Matrix—might life and the world as we know it be a simulation on a super advanced computer?

Nowadays, the tools for tracing your family tree have advanced far beyond looking back at names in the family Bible or compiling a scrapbook of paper records. Using your genetic information to find long-lost relatives is easier and cheaper than ever before—and scientists are looking to push the technology even further by analyzing our skin and facial features.

Lemurs, capuchin monkeys, and macaques help cognitive psychologist Laurie Santos understand how we think and are able to use tools, do math, and perform other tasks that make us human. …

Albert Einstein spent his last thirty years unsuccessfully searching for a ‘unified theory’ — a single master principle to describe everything in the universe, from tiny subatomic particles to immense clusters of galaxies. In the decades since, generations of researchers have continued working toward Einstein’s dream.
