Joe Rogan and Neil deGrasse Tyson have in-depth discussion about the Big Bang and Multiverse

Joe Rogan recently sat down with world-renowned astrophysicist Neil deGrasse Tyson on the Joe Rogan Experience (JRE) podcast and the two went deep on the topic of the Big Bang and the Multiverse theory.

On the latest edition of the JRE podcast (#1904), the 64-year-old and the UFC commentator discussed the reach of technology and our understanding of the birth of the universe. Speaking on the accumulation of empirical evidence and using it to build an understanding of our universe, deGrasse Tyson said:

"If you have an idea about something then you test it. Multiple ways. And get other people to test it. If the tests give you consistent results, you have a new understanding of the universe. When that happens, that [Previous] knowledge of the universe does not go away... You have a deeper understanding of the universe in which that understanding gets embedded."

When Joe Rogan and Neil deGrasse Tyson talked about how some infinities are bigger than others

Joe Rogan had his mind blown by Neil deGrasse Tyson when the astrophysicist explained to the popular podcaster the concept of some infinities being bigger than others.

On a past episode of the Joe Rogan Experience (#919), deGrasse Tyson was asked to explain the concept of the mathematical possibility of the "infinite" and how theoretically a universe would go on forever and include every possibility — including endless versions of ourselves. The 64-year-old stated:

"Some infinities are bigger than others... Not all infinities are the same size... For example, the number of counting numbers 1,2,3 up to infinity, the numbers you would use to count things, that's infinite. The number of irrational numbers... there are more of those than counting numbers."

The astrophysicist further continued:

"The way to demonstrate that mathematically is you map one item in the set of this inifinity to a corresponding item in the set of the other infinity... You keep doing this and you find that [mathematically], one inifinity outstrips the other infinity and you're left with more numbers."
