Olaf Dreyer, a theoretical physicist who did his PhD with Abhay Ashtekar and now works in finance, joins to explain how he thinks spacetime and matter emerged together. We discuss black hole spectroscopy, the test he and his collaborators proposed and LIGO later ran. Olaf found that 0.04 in a condensed matter textbook, the same value as the tilt of the cosmic microwave background. He argues this means our world began in a phase transition, and he sketches a new way to implement the equivalence principle. The conversation also covers Robert Laughlin’s bucket of water, what banking taught Olaf about funding physics, and consciousness.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://tinyurl.com/paypalTOETIMESTAMPS:- - - - - - - - - - - - - - - - - - - - LINKS:- The World Is Discrete [Paper]: https://arxiv.org/abs/1307.6169- Black Hole Spectroscopy [Paper]: https://arxiv.org/abs/gr-qc/0309007- Quasinormal Modes, the Area Spectrum, and Black Hole Entropy [Paper]: https://arxiv.org/abs/gr-qc/0211076- Olaf's Papers: https://inspirehep.net/authors/1021936- Principles of Condensed Matter Physics [Book]: https://amazon.com/dp/0521794501?tag=toe08-20- A Different Universe [Book]: https://amazon.com/dp/046503828X?tag=toe08-20- AQFT: https://plato.stanford.edu/entries/quantum-field-theory/- LIGO Black Hole Collision Sound: https://www.ligo.caltech.edu/video/ligo20160211v2- LISA: https://lisa.nasa.gov/- Lee Samuel Finn: https://web.archive.org/web/20141020034610/http://gwastro.org/us/lee-samuel-finn- Rob Laughlin: https://www.nobelprize.org/prizes/physics/1998/laughlin/facts/- DESY: https://desy.de/index_eng.htmlFull reading list for this episode (all 61 sources): https://curtjaimungal.comGuests do not pay to appear. #scienceLearn more about your ad choices.
