The exact text of my opinion piece was too long to copy it here, so I put it up on my blog: http://backreaction.blogspot.com/2021/07/can-physics-be-too-speculative.html You can support me on Patreon: https://www.patreon.com/Sabine 0:00 Intro 1:05 Progressive of Degenerative? 3:23 Dark Matter 4:39 Fifth Forces 5:17 String Theory 6:22 Multiverses 6:55 Alien Technology 8:56 Sponsor Message #physics #science
