StarTalk | Exploring Hidden Dimensions with Brian Greene

Is our universe an inevitable outcome of the laws of physics? Neil deGrasse Tyson and comic co-host Chuck Nice sit down with theoretical physicist Brian Greene to discuss the Many-Worlds Interpretation, the structure of the multiverse, levels of infinity, and respond to cosmic queries Neil couldn’t answer. have stalled?

What’s the difference between a multiverse and the many worlds interpretation?

We explore Hugh Everett's Many Worlds interpretation and how it arose not from wild speculation, but from a conservative reading of the equations. Is math a supreme account of reality or just a tool for understanding more?

We explore time where following the math didn’t quite work out.

The trio dives into Hilbert space, Gödel's incompleteness theorems, the different sizes of infinity, and what it actually means for another version of you to exist in a parallel universe.

They wrestle with the Many-Worlds Interpretation: if every possible outcome is guaranteed to happen somewhere, what does "unlikely" even mean?

They also explore where these other universes actually are, whether you could ever reach them, and why gravity might be the one force capable of leaking between dimensions while light stays anchored to our membrane.

How is gravity and the other forces represented in string theory? Brian breaks down string theory: its origins, its extra hidden dimensions, and why after 40 years it still hasn't produced a testable prediction. Could AI be the breakthrough that cracks it where human physicists have stalled?

Then it's on to Cosmic Queries, where fans ask about the black hole information paradox and whether Hawking radiation destroys quantum information. Could a spinning universe explain cosmic expansion as centrifugal force? What does supersymmetry fix about the standard model? Could entanglement be explained by secret wormhole shortcuts?

We explore quantum immortality, detecting extra dimensions and if time could be an emergent property of light. We discuss the quantization of gravity and whether life is inevitable given the laws of physics. Keep Looking Up!
