Curt Jaimungal talking to Ivette Fuentes and Roger Penrose About Experiments in Gravity and Quantum Physics

My Comments:

47:40 Roger Penrose says we see gravitational fields. Don't we infer those fields from observations we make of massive objects? And whatever apparatus we use to make these observations, whether that apparatus is our own eye, or maybe a flea's eye, then that apparatus must be located at some point and be in some definite state in order to make the inference possible. I just don't get the fuss about why we never see massive objects in superposition states. What would that even mean? Because of this cognitive disability of mine I find it impossible to make any sense of what most theoretical physicists say. 50:48 The "fact" that dark matter is most of the stuff in the Universe is another inference from exactly those observations of the behaviour of visible matter in gravitational fields. Most reasonable people, I think, would just conclude that we do not have a good model for the behaviour of visible matter at large scales. [a few hours later this appeared]

28:31 In case you missed it, because you were buying a mattress or you don't subscribe to Curt's substack, that paper is "Exploring the unification of quantum theory and general relativity with a Bose–Einstein condensate" by Richard Howl, Roger Penrose and Ivette Fuentes, published in New J. Phys. 21 (2019) 043047. [in Safari on an iPhone this number (2019) …  appears as a phone number hyperlink]

Welsh Republic Podcast Talking With Kars Collective on Armenia Azerbaijan Conflict

  In the last 30 hours, Azerbaijan has blocked the Berdzor Corridor (the only route in and out of Artsakh), established a military police presence, threatened to shoot any flying object leaving the capital Stepanakert, and has now cut the gas supply. This is now a blockage. — Kars Collective (Կարսի Կոլեկտիվ) (@KarsCollective) December 13, 2022 Subscribe to Welsh Republic Podcast .
