Jim Al-Khalili, theoretical physicist and Distinguished Professor Emeritus at the University of Surrey, joins to argue that the arrow of time is fundamental. Entropy increases because the arrow already points that way, and not the other way around. We discuss why he thinks the measurement problem is taught badly. He wants Bohmian mechanics to be right without claiming that it is, since the price is Einstein’s special relativity. He calls the past hypothesis a cheat. The conversation also covers the block universe, where he parts ways with Carlo Rovelli, and why he wants thermodynamics in the search for quantum gravity. I hope you enjoy.FOLLOW:- Spotify: https://open.spotify.com/show/4gL14b92xAErofYQA7bU4e- Substack: https://curtjaimungal.com- Twitter: https://x.com/TOEwithCurt- Discord: https://discord.gg/kBcnfNVwqs- Crypto: https://nowpayments.io/donation/TOE- PayPal: https://www.paypal.com/donate?hosted_button_id=XUBHNMFXUX5S4TIMESTAMPS:- - - - - - - - - - LINKS:- Jim Al-Khalili's Website: https://www.jimal-khalili.com/- On Time [Book]: https://amzn.to/46PNLxK- Jim Al-Khalili's Channel [Video]: https://www.youtube.com/@UnbaffledScience- Quantum Reality Series [Video]: https://youtu.be/sivQ-jbZ2oM- The Decoherent Arrow of Time and the Entanglement Past Hypothesis [Paper]: https://arxiv.org/abs/2405.03418- Block Theory: https://plato.stanford.edu/entries/time/- Copenhagen Interpretation: https://plato.stanford.edu/entries/qm-copenhagen/- Many Worlds: https://plato.stanford.edu/entries/qm-manyworlds/- Bohmian Mechanics: https://plato.stanford.edu/entries/qm-bohm/- Bell's Theorem: https://plato.stanford.edu/entries/bell-theorem/- Collapse Theories: https://plato.stanford.edu/entries/qm-collapse/- Schrödinger's Cat: https://en.wikipedia.org/wiki/Schr%C3%B6dinger%27s_cat- Loschmidt's Paradox: https://en.wikipedia.org/wiki/Loschmidt%27s_paradox- Thermodynamic Asymmetry in Time: https://plato.stanford.edu/entries/time-thermo/- Space and Time [Paper]: https://en.wikisource.org/wiki/Translation:Space_and_Time- The Strangest Man [Book]: https://amazon.com/dp/B002LDM8QS?tag=toe08-20- Beyond the Quantum [Book]: https://amazon.com/dp/0198853742?tag=toe08-20- The Selfish Gene [Book]: https://amazon.com/dp/B01GI5F2FS?tag=toe08-20- Universe Today Article: https://www.universetoday.com/articles/quantum-physicist-takes-aim-at-the-universes-mysterious-arrow-of-timeFull reading list for this episode (all 37 sources): https://curtjaimungal.comGuests do not pay to appear. #scienceLearn more about your ad choices.
