Two Astrophysicists Debate Free Will

Does free will exist? Neil deGrasse Tyson and Chuck Nice sit down with astrophysicist Charles Liu sit down to discuss the existence of free will and whether physics allows for choice in our lives.

We explore cause and effect: how does uncertainty and chaos in the universe factor into free will? How important is the illusion of free will to society? What does a society that acknowledges a lack of free will look like?

Note for the fans who caught it: the visual of the “Quarterback” evading the sack was actually of Running Back Christian McCaffrey—we’ll stick to the physics field 😉.

    Did you click on this video out of your own free will?

    Bold of these gentlemen to assume that I exist in the first place.
  • @user-js5om1nk8t
    “I want to compare notes” I love that friendly way of saying let’s have a debate
  • This is how adult conversations should go. I really enjoyed this
  • @RobertSpitzer
    I had no free will in watching this video. Every moment of my life leading up to this point left me with only one option.
  • @zachkamran9688
    This is such a good, true debate. They aren’t arguing against each other, they are testing ideas in a mutual effort to establish a truth. Beautiful
  • @tommym875
    It’s so refreshing to see three grownups sitting together and having a civil discussion about a complex and nuanced topic.
  • @luketien928
    Watching these two (Neil and Charles, and even to a great extent this time, Chuck) discuss the differences between their opinions is like watching two enormous beings, gigantic in their intellect, awesome in the thoroughness that they thought things through, and inspiring in their articulation, pitting all of their knowledge, understandings, and skills in communication, in a titanic effort to overcome one another. Yet, in the end, they shook hands in unadulterated respect for one another, because while neither has managed to defeat their opponent, both have learned great things from the encounter.

    Charles Liu was my professor in 2015. One of the very few that left a lasting impression on me. It's good to see his enthusiasm has remained unchanged.
  • @CUBOSH
    Charles Liu is your best guest -- he should be a regular on the show. this guy speaks with crystal clarity
  • This show reminded me of a time when my son was young standing next to his dad and the both stood the same way. Later I saw a photo of his great grandfather and he was standing the exact pose.
  • @BartJBols
    Chuck really became part of the conversation tbh, instead of in the early days just being comic relief. He actually adds useful perspectives and engages with the matter that is a unique but contributing perspective.
  • @Platter_heads
    The first explanation of causality , if taken serious, can really put a halt in the response of correlation usually given when people make arguments for cause.
  • @alkevinzmedia
    What an amazing StarTalk episode. Really loved this one.
  • @Silensio
    Arthur Schopenhauer said: "Man can do what he wills but he cannot will what he wills."
  • I loved this! This is what debating should be like more often: leaving the egoes at the door, listening intently and openly to what one another are saying, respecting each other, and also genuinely trying to better understand the subject at hand vs. one-upping the other person. I found the conversation very interesting and entertaining. Thanks y'all!
  • @Dustbowl121
    Well said! I always love this conversation!
  • @levelupii4663
    I “liked” the video after only seeing the title and speakers. Listen - I cannot WAIT to hear this entire podcast. So freaking excited!! 🤩🔥🔥🔥
