Lawrence Krauss | 'The Universe Doesn’t Care About Us... And That’s Beautiful' - The Beginning & End Of The Cosmos + Reflections On Hitchens

1d ago 45:41

MP3•Episode home

Theoretical physicist and bestselling author Lawrence Krauss (A Universe from Nothing, The Known Unknowns) explores the biggest questions we can ask:
How did the universe begin? Why is there something rather than nothing? What is consciousness? And what will remain when every star has burned out?

Krauss moves seamlessly from the hard science of the Big Bang and dark energy to existential philosophy, arguing that our cosmic insignificance is precisely what makes life meaningful.

Along the way he shares personal stories—mentorship from Nobel laureates, serendipitous discoveries, his friendship with Christopher Hitchens—and explains how curiosity and rigorous science drive human progress.
