You’ll learn about the differences between human and chimpanzee DNA and what that could mean for humans in comparison to highly intelligent aliens. Do we have the intelligence of an alien toddler? Is the universe out of reach of the human brain? We debate how long humanity will last and you’ll hear why Neil has confidence humanity will last given the collective nature of our intelligence.Then, we dive into the big question: what is the meaning of life? Neil shares his thoughts on how he finds meaning in his own life. Discover more about the “vacuum” of space. How far behind or ahead we’d be if we didn’t have moon? Lastly, you’ll learn about higher dimensions and if they’re bleeding into our own universe.
