Reading Roger Penrose always reminds me of Sir Arthur Conan Doyle. Two very clever people gradually going doolally.
Doyle wrote brilliant literature and then in a state of batshitness decided to claim fairies actually existed in reality . In a way, from writing so much fiction, he might be excused.
Not so for Penrose.
Roger Penrose produced some brilliant mathematical physics on General Relativity which developed outstanding science and then he decided, despite key errors being pointed out to him, that gravitational waves cannot be allowed. This was only because he basically wants to link gravity to consciousness. The kind of genius which can postulate far-out-there science, is done no favors when it relies on rejecting fundamental physics.
Unfortunately for Sir Roger, last year the evidence for strong gravitational waves was discovered.
The outstanding accomplishments of Penrose won't be changed because he became hooked on fantasy but at least it was one that outshone Conan Doyle's.
Nevertheless despite himself, hopefully the overall legacy of Penrose will remain that of an amazing scientist and humanitarian.
