Cosmic Queries – Understanding Infinity with Stephon Alexander

About This Episode

What is infinity? Neil deGrasse Tyson and comedian Negin Farsad explore whether we are in a finite universe, the issues with infinity, string theory, and more with theoretical physicist Stephon Alexander.

Is infinity just a cop-out for something we don’t understand? Learn some everyday examples of infinity and how Einstein’s relativity led to the singularity. Is it real? How can you have infinite anything? Could there be new physics in the middle of black holes?

What are some other singularities in physics? Discover how quantum physics was supposed to fix classical physics and how it continues to get more complicated from there. Is infinity inevitable? How could multiple universes exist within a finite universe?

Find out ways that the Earth is infinite. How does string theory work and what does it have to do with music? How do we compensate for human biases and deficiencies when tackling the concept of infinity? What is quantum loop gravity? Finally, if the universe is under no obligation to make sense to you, can you still make it make sense?
