Reviews

4.5 out of 5 stars from 2.6k ratings
  • Please keep God out of your discussions

    This could be such a solid production but unfortunately Brian Keating is increasingly bringing religion into the discussions. Those interested in religious philosophy have a multitude of podcasts to choose from and can hear from real theological experts. This podcast is always at its best when it sticks to pure science.

  • Too much religion

    This guy has plenty of intelligent things to say but he’s such a religious zealot that it doesn’t take long for him to become tiresome. Plus he’s a big cheerleader for the intellectual fraudster Eric Weinstein and that should be enough reason for anyone to turn him off.

    Think like a physicist and wonder like a human…and always talk to people who have different view points. His podcasts are always at least interesting and at most deeply game changing.

Talking Points

Recent interactions between the hosts and their guests.

Princeton Mathematician: Wormholes Can’t Survive Einstein’s Math
Q: Are wormholes real objects in the same sense that black holes can be considered real?
Klainerman says wormhole solutions are extremely unstable in classical general relativity, so he does not consider them physically meaningful in that setting. He notes that Juan Maldacena may argue they have a role in quantum mechanics, a topic outside his expertise.
Princeton Mathematician: Wormholes Can’t Survive Einstein’s Math
Q: What does it mean fundamentally for something to be stable rather than unstable?
Stability means that after a small change to the initial conditions, the resulting solution stays close to the original or converges back to it over time. This matters because exact solutions do not occur in physical systems, so a physically meaningful solution must withstand perturbations.
Are We in a SIMULATION? | Brian Keating on the Arora Podcast
Q: As a physicist, do you think that something science should take seriously, or is it mostly just a fun thought experiment?
Keating sees little practical benefit in treating simulation theory as a serious scientific explanation. He says it may be possible to test for discrete limits in physical observations, but such findings would still invite arguments about whether they were part of the simulation.
Are We in a SIMULATION? | Brian Keating on the Arora Podcast
Q: Do you think there is anything at all that cannot be answered by science even in the future?
Keating says science addresses a limited set of questions and is better at eliminating false explanations than proving underlying truths. He emphasizes that scientific knowledge is modest compared with what remains unknown.
Wharton AI Researcher: If AI Froze Today, It Would Still Rewrite Work
Q: If your kids were young, when would you give them access to these very powerful super intelligences?
Mollick recommends close supervision, shared creative projects, avoiding AI shortcuts for younger children's learning, and using age-appropriate study modes for high school students.
