> It is hard to believe how entrenched locality and realism are in physics Not really, since every valid theory must be testable and falsifiable. The idea that all of reality has been a fleeting random agglomeration of particles that experienced this exact moment, of you reading my sentence here, before dispersing and taking all of suggested reality with it - in other words, a Boltzmann brain - well, it's a cool idea, but where does it get you? It's not falsifiable, ever, so it's not science. It's philosophy, and as such it's not something that a scientist, let alone a whole field of scientists, should be spending their time on. Instead, they should be doing actual science, grounded in realism. If they want to put on a philosopher hat after work and talk about Boltzmann brains, on the other hand, that's great. I, for one, will lap up the crazy philosophies generated by the mind of a physicist, with gusto. But I'd rather they (or so least, most physicists) stick with actual science, aka, their job, most of the time.
