"Palatial Twistor Theory; in order to describe a general, Lorentzian, globally hyper-bolic 4-dimensional space-time in twistor terms, we appear to be driven to a holomorphic non-commutative twistor-geometry, even for Classical space-time."

per article: "we appear to be driven to a holomorphic non-commutative twistor-geometry, even for Classical space-time.""

Gee whiz, isn't it obvious? I thought everybody knew that …

Sounds pretty holomorphic to me.

What does Chubby Checkers say about this?

It may work for those who live in Classical space-time but for those of us living in Hard Rock space-time the theory falls apart pretty quickly.

Sir Roger Penrose: Fashion, Faith, and Fantasy in the New Physics of the Universe
Copernicus Center
January 1, 2017
https://youtu.be/kS1A5dJdOvI
(1:43:05)

Arguing that string theory has veered away from physical reality by positing six extra hidden dimensions, Penrose cautions that the fashionable nature of a theory can cloud our judgment of its plausibility. In the case of quantum mechanics, its stunning success in explaining the atomic universe has led to an uncritical faith that it must also apply to reasonably massive objects, and Penrose responds by suggesting possible changes in quantum theory. Turning to cosmology, he argues that most of the current fantastical ideas about the origins of the universe cannot be true, but that an even wilder reality may lie behind them. Finally, Penrose describes how fashion, faith, and fantasy have ironically also shaped his own work, from twistor theory, a possible alternative to string theory that is beginning to acquire a fashionable status, to “Conformal Cyclic Cosmology,” an idea so fantastic that it could be called “conformal crazy cosmology.”

I never realized there was such complex thinking about this. I just put my left foot on yellow and my right hand on blue without thinking.

Palatial Twistor Theory. Oh, my. I guess Occam’s Razor is out of favor these days.

That’s the way to shut down Al Gore’s religion: put anyone who accepted grant money under oath and make them testify about their findings. It’ll be over in ten minutes, if that.

That was my initial opinion, but then I had to put my left hand on the red. Well, things got a little complicated after that.

I thought “Twister” was a good movie. Lots of twists and turns in its plot.

Next: Muppets and Wormholes - Can they exist together?

There is a strange connection sometimes between geniuses and certifiable insanity. Their own ego allows their imagination to let them assume that because they are so “smart” some fantastic imagination of theirs must also be a “smart” idea.

When math veers from looking at what is to pretending that merely because you can invent something, mathematically, it must exist, you know you have gone from science to fantasy.

A truly terrible lecturer. I imagined 3/4 of the audience going to sleep, out of frustration.

Obvious case of plagiarism!
Seem to remember Joe Biden and John Fetterman proposing this same concept at their last press conference...
