Have to say a bit shaken by the attitude towards alternative viewpoints, (and Penrose!) in the audience. See 2m45s.
This opinion video has a few short excerpts from an excellent video on gravitational entanglement given at the Perimeter Institute on Sept 21, 2022. See PIRSA.org for the entire video.
The most interesting bit is at 2m45s where the audience laughs at pre eminent physicists. The speaker, Markus takes pains to show how in 1905 – 1925 no one actually believed in photons. Physics had a closed mind. Markus it seems is not happy with the audience when they start laughing at people. Contrast with the Bohr quote from 1925 closer to the start of the video, where Bohr made a joke (that is even funnier today).
Fast forward to 2022, and we see the same thing as the audience (not the speaker) laughs directly at Roger Penrose and many General Relativity theorists (I’m with the GR people here). The simplest way to show that gravity can’t be quantized is to look at the 1000+ researchers who spent three decades trying and utterly failing. It does not and will not work. Get over it and get on with it. See also https://twitter.com/TAndersen_nSCIr/s… And https://gravityphysics.com/Show less
