#136 - Geraint Lewis On Creation, Super Intelligent AI & The Meaning Of Life

Geraint F. Lewis is a Welsh astrophysicist, best known for his work on dark energy, gravitational lensing and galactic cannibalism. Lewis is a Professor of Astrophysics at the Sydney Institute for Astronomy. He is currently Deputy Director of the Sydney Informatics Hub, a core facility of the University of Sydney.

We kick it off with Geraint briefly giving us his background right before jumping into the thick of it with a topic such as dark matter. The topic shifts to human knowledge and the limits of our understanding, then onto multiverse theory, physics and the Big Bang! Tommy chimes in with questions about God and science, then proceeds to ask Geraint about his views on religion.

The conversation gets better and better as they verge into the realm of super intelligent AI’s, a bit of politics, more on multiverse theory, looking for signs of life in the universe, intelligence and consciousness.

This episode is a definitely a ripper! Geraint was great to have, and we just had so many questions we wanted to ask. Sadly, our time was limited - so here’s 2 hours of pure science-y goodness for all of you. Enjoy the show, guys!
