Sir Roger Penrose: Challenging Modern Physics Theories

Click For Summary
Sir Roger Penrose critiques modern physics, labeling string theory as a "fashion," quantum mechanics as "faith," and cosmic inflation as a "fantasy." His reputation as a respected physicist, known for his work on black holes with Stephen Hawking, lends weight to his controversial views. Penrose argues that current theories may have foundational issues and suggests that alternative explanations could better account for our observations of the universe. While some acknowledge his intellect, others express concern that his recent ideas, particularly on quantum consciousness, lack experimental support. The discussion highlights the ongoing debate within the physics community regarding the validity and future of established theories.

Apparently there is a consensus Penrose is an amazing intellect. Even a genius like Einstein makes an occasional error. That in no way diminishes their contributions to our body of knowledge. Personally, I still find his insights amazing.

His past work was excellent. I have been exceedingly disappointed by the things he's been proposing lately. The CCC in and of itself was a curious idea, but highly unlikely from the start. What disappointed me was that when he tried to make use of CMB data to back up his idea, he completely and utterly misunderstood the basic statistical properties of the CMB, and his arguments to try to back up his interpretation were just terrible. This shows that he's willing to step into a field he hasn't learned much about and not do his homework before jumping to unwarranted conclusions.

This quantum consciousness stuff is much, much worse.

He was well-respected. He did a lot of important work in decades past. Essentially anybody who studies General Relativity these days knows his name.

But sadly, I think he's spent that respect. It's really unfortunate, but he seems to have become rather divorced from reality. It's really too bad.
Ironically, some years ago he wrote a pretty good popular-science book (not of the usual kind but with a lot of mathematics ;-)) with the title "The Road to Reality". There's a lot of standard physics in this book explained in quite unusual ways, but it's still standard physics. Some parts are, however, already then his personal opinion with incomplete scientific justification.

That was true in his previous popular books as well: The Emperor's New Mind and Shadows of the Mind.
