I couldn't conceivably substantively speak....

 

of the prevailing opinions of professional physicists, but my take on your question is that most working physicists adhere to those two theories in and of themselves (for the extraordinary effectiveness of what they can explain), but are of course looking at how best to unify them - the purported grand theory. However, Deutsch here doesn't even adhere to those two theories individually, much less in unison. His evident professional objective is to find substantially new alternatives to both general relativity, and contemporary quantum mechanics (his insistence on basing 'his' QM on the Heisenberg interpretation due to its locality, and building from there). Personally, I am not a professional physicist, so I don't have objections to either the Schrodinger version of quantum mechanics, or to Heisenberg's, whether the universe splits into multiples upon an observation event solely locally, or to the 'edge' of space (another theoretical concept altogether) is simply a fascinating concept to ponder........ thanks for looking and commenting, much enjoyment listening to the Mindscape podcast!

For the science geeks here, I just wanted to share this relatively recent interview with Dr. David Deutsch on the Mindscape podcast with Dr. Sean Carroll. I've listened to it three times over the past few months........ ...  

Believe it or not…

just two days ago, my friend and I got into a bit of a heated discussion about physics (yes, I know that may be a very odd topic for casual conversation)…and it wasn’t the first time, although I had never previously engaged so vehemently as I did this tim... 

Deutsch....

Is a wonderfully oddball physicist whose beliefs and work are as against-the-grain relative to contemporary academia as it gets. He believes neither general relativity nor quantum mechanics to be sufficiently accurate theories of the universe. It's going ... 

I may be wrong...

But don't most physicists believe that neither quantum nor relativity to be able to explain the universe? Hence the search for the grand unified theory? In any case, thank you for pointing me to the source of my commute listening for the next few weeks!

Listening to this podcast made me revisit some topics that I haven't thought about in years. It seems to me that the major points Prof Deutsch makes all boil down to - Bayesian priors, credencies as he calls them, are actually conditional on a pre determi... 

I have to say....

I totally agree with your observations. I wasn't aware of his comments on Twitter as I don't use or generally view the platform. Personally, I am on the side of Dr. Carroll's views and opinions, that's why I diligently listened to the vast majority of his...
