50 years of the world’s most powerful intellects working on a post-modern physical theory w/ as yet no known connection to physical reality. I don’t really know what to say. This is likely the greatest intellectual bubble in history. Let’s hope they take the training wheels off.https://twitter.com/bgreene/status/1035956250184478720 …
And just to anticipate the expected comparisons, this is an actual intellectual bubble. Not an ideological bubble. Not a pseudo intellectual bubble. Not a propaganda bubble. These are true intellects experiencing the greatest fall from the highest of heights. They’re true giants.
The drift of physics into unfalsifiability is over:https://link.springer.com/article/10.1007/s10509-017-3128-6 …
It’s truly odd that unfalsifiable hypothesis were taken on by others. When teaching science to kids unfalsifiability is a core test in formulating hypothesis.
Physicists all pay lip service to falsifiability, but they soon work out that avoiding it, by becoming abstract, is a quick way to avoid embarrassment.
I disagree. "String theory" is not a theory, it is a framework of consistent quantum theories which reduce to Einstein's gravity at long distances. No other framework does that. Having *a* theory of quantum gravity is not the same as having *the* theory of quantum gravity.
Analogously, "gauge theory" is not a theory, it is a framework of theories with local redundancy. Most are unphysical, many are inconsistent. But plug in the right redundancy, the right matter content, and you get all of particle physics!
And yet, despite not knowing what to say, you can't keep yourself from speaking.
Damn, shots fired
Shots fired into his own foot.
String theory has made experimentally verified predictions through holography! It correctly predicted the ratio of shear viscosity to turbulence of a quark gluon plasma for example
That's not correct... holographic analogues of QGP hold (conjecturally) the lowest theoretical value for such a ratio, but even though real-life QGP displays a very low value, it confirms nothing: the holographic models do not reduce to the correct theory of strong interactions.
At best, it props up the hopes of finding a holographic model of quantum chromodynamics (not of highly symmetric analogues of it, as is the case) that postdicts such a find.
Awful take; please see my retweet
Rather than saying ‘see my retweet’, why don’t you just copy and paste what you said in your retweet?
After reading my first book on string theory in 2003, I remember thinking, "Don't all of these smart people realize they are working on a giant analogy?" I never revisted the topic again.
I get that feeling about the entirety of particle physics: Invent new equation (pretty lattice) to fit previously-discovered particles, note un-filled holes, build giant collider, fill holes, rinse, repeat. It's lattices and equations all the way down folks. Save your billions.

“anything I don’t understand is post-modernism”
Just what exactly do you think "post-modern" means?
“Every thing I don't like or can't be fucked to understand”.
