1/ "Theories of Everything": A Taxonomy.
It is often said that "Theories-of-Everything are a dime a dozen" or that "All theoretical physicists worth their salt have several in a drawer." So far as I can tell, this is simply untrue. We've barely ever, if at all, seen candidates.
2/ The Escher Lithograph used in the first tweet points to the core of why TOEs are rare. A candidate TOE has to have some quality of "a fire that lights itself", which is difficult to think about beyond the equations that would instantiate it. Hence very few such theories exist.
3/ I'm going to lean on the following dictionary of analogies:
Physical Paper = Void Pictured Canvas = Manifold and/or Einsteinian Spacetime Ink=Matter & non-gravitational force fields Pencils = Pre-Conscious Lego (e.g. amino acids) Hands = Consciousness Paradox = Self-awareness
4/ In my taxonomy, Type I TOEs are our least ambitious but they best match our state of the world. They are distinguished by two *separate* sources of origin: one for the Canvas (General Relativity or Witten's point i) ) & one for the Ink (Standard Model or Witten's point ii) ).
5 Type II TOE's are more ambitious & seek to derive the Ink from the choice of a mathematically distinguished Canvas that is anything but blank. My arch-nemesis @garrettlisi's theory is Type II. E8 is his 248 dimensional canvas. The intricacy is there, but doesn't quite match up.
6/ In Type III TOEs the ink is to be derived from canvas, but the canvas is essentially blank; it simply permits mathematics to happen (e.g. calculus and linear algebra). In such theories the ink has to be bootstrapped into existence. My lectures on Geometric Unity were Type III.
7/ Type IV TOE's try to change the question from Einstein's "Unified Field Theory." In String Thy, "Quantizing Gravity" became substituted for "Unified Field." For this crowd, many are now betting that the canvas & ink are both *emergent* from some deeper fundamental quantum thy.
8/ Type V TOEs are of a type I've never been able to fully contemplate; they are without boundaries or origins. There is no "Why is there something rather than nothing" within them. That which is not forbidden is compelled into existence. Void creates canvas & canvas begets void.
9/ Type VI TOEs begin with the hands. Religions are of this type. I pass over this in silence as they aren't scientific.
I will leave open higher types, but I've really only seen attempts at I-IV & I wouldn't call String-Thy/M-Thy a full TOE try since events of the last 15 yrs.
10/ I believe fundamental physics is stalled out because we are finally at the doorstep of a TOE and we haven't really bothered to think about what that would actually mean because we've never been here before. A final step need not look like any previous one. In fact, it cannot.
END/ My bet is on Type III for a reason:
Type I is not unified.
Type II is possible, but appears to be unworkable in details.
Type IV appears to lack sufficient guidance from Quantum theory to actually 'ship' despite consuming resources for yrs.
Types V & VI lack any progress.

It really depends. Being totally honest:
âString Theoryâ has done a *tremendous* amount of good while âString Maximalismâ has done even more harm.
If the String Theorists who led the movement were to undo some of the damage by admitting what happened, itâd be a major positive.
Here is where I respectfully disagree with my colleague @skdh. You canât âget rid of string theoryâ. String-like objects are natural and have an unbelievably rich and beautiful interlocking mathematics. The beguiling beauty isnât the problem in my opinion. Beauty is the excuse.
The problem is that string theory on its own has taken the last 40years to PROVE it doesnât work as a stand alone path by gobbling up mind share, students, resources and (to be fair) most of the most brilliant brains. So much that no one dares say the full extent of the disaster.
During that time String Theory diverted the entire field into a magical never-land of âtoy physicsâ. Models that arenât in any way real. You now have âparticle physicistsâ at the end of their careers who have never worked with anything like a particle and canât remember them.
So, hereâs my analysis. In a world where David Gross, Ed Witten, Lenny Susskind, Cumrun Vafa, Michio Kaku had a public Come To Jesus moment where they admitted the disaster in front of the community faithful, Iâd be up for having ST as a major theory. But without that Iâm unsure.
The damage to the culture of High Energy Physics is more severe than the damage done by Geoffery Chew in a different era. And here I support @skdh, Peter Woit, Lee Smolin etc. These are brave people who paid with abuse to communicate that physics was diverting into pure fantasy.
So to sum up:
String Theory deserves to be a major branch. But it has already mostly given up on the â80s promises/lies it told us to gobble up all the resources of the community (brains, mind share, $$$). That was a crime which may prove fatal to our being able to do physics.
But it is also so thoroughly investigated and badly behaved relative to scientific norms that it deserved to be shrunk. And that happened to a large extent already. The most important thing to realize is that physics is still about the physical world. Not Calabi Yau. Not AdS/CFT.
And we need our brilliant failed string theorists to admit the disaster within a scientific paradigm.
Science is a culture. Perhaps the most fragile one. It wonât survive this suspension of collegiality, decency and self-critical behavior. We need to go back to real physics. đ
@martinmbauer String theory was a giant percentage of a tiny priesthood. That was the same tiny priesthood that brought us Thermo Nuclear devices. And if you want to pay for me to research the numbers Iâm willing to hire somebody to put together the data after 1984. Itâs not usually contested.
@DontsitDJ @martinmbauer I wasnât aware of it like that. I think he disagrees with me and has a bit of an edge. But maybe I missed a tweet or two. I havenât seen much interaction and he has written some things I liked.
@DontsitDJ @martinmbauer I love a good critique. Itâs hard to find. Most people out here develop a side hustle in interpersonal drama. I try not to.
@martinmbauer I donât know which version of âThe Fieldâ you mean.
Physics in total? Is a large field.
Beyond the standard model theory? Is a small field. Tiny. But hugely consequential. And the percentage and effect wasnât small. Do you really dispute this??? Look at the IAS professors.
@martinmbauer Seiberg/Witten/Dijkgraaf/Maldacena
All string folks.
Maybe get a string theorist to admit this to you. Brian Greene likely wouldnât disagree with me.
Physics in 1980: âIâm trying to grasp why nature has 3 generations of chiral fermions with SU(3)xSU(2)xU(1) internal symmetry.â
Physics Today: âRemind me again what the internal quantum numbers are? I do quantum gravity so itâs not something Iâve worked with since my QFT class.â
What has string theory done to become the poster child of failed physics? It hasnât even failed.
A) High energy physics of real particles became the no-energy physics of toy models.
B) Quantizing Gravity was substituted for unification or extension of the Standard model.
C) Other research programs were obliterated because ST claimed it had it all rapped up.
D) Hype won.
E) Focus shifted to mathematical structure of abstract field/String/M theory. Not our particular worldâs choice of thy.
F) Standards of scientific progress were rewritten to disguise failure.
G) Differential application of standards became the norm.
It ended physics culture
String Theory isnât the problem. String culture is poisonous to science.
String theory, like love, means never having to say your sorry. Or mistaken.
Itâs the January 6 problemâŠbut in science. But where the physics versions of Mike Pence often got fired for not going along. đ
*youâre
P.S. âIt hasnât even failedâ because it canât fail. So far as I can see, it can never fail. In the minds of the faithful, Itâs unable to fail because it *has* to be the way forward. Itâs hard to explain whatâs wrong with that to the enlightened who see its infinite power & glory.

@DrBrianKeating I am not aware that the standard model and GR âwork fineâ: CKM, PNMS, Strong CP, Mass Hierarchy issues, CC origin, origins of internal symmetry, initial singularity and black hole singularity, Miniboone, etc. all require explanation.
If thatâs what she means, I say itâs wrong.
One of the questions about UFOs that needs to be asked, and that I donât hear much about, is: âHas the US government built fake UFOs?â
UFO people are so focused on whether there are real UFOs that they donât push hard enough on this question.
Allow me to share a thought or two.
When I first realized I was totally wrong about UFO/UAP, I was shocked by how many folks have very similar stories about recovered crashes of very similar advanced vehicles.
It was mind blowing in 2 ways.
A) We have real crashed vehicles. And/Or B) We built fake alien vehicles.
At this point Iâm reasonably sure there are things that look like cool alien vehicle in some hangers. But I also grew up near Hollywood and remember super cool looking fake space cars visible off the Hollywood freeway.
So: does anyone have stories of building fake UFOs for USG?
As you likely guessed, all the photos in this thread are fake military equipment. The airbase is totally fake. The dummy tanks are often inflated on the battlefield. The fake tank pieces are bolted on to real cars.
Q: Did we build fake UFOs in places like Wright-Patterson AFB?
After studying this issue for 2yrs, Iâm pretty convinced that there ARE wild looking vehicles in secret high security locations. But I also find NO SIGN OF OUR TOP PHYSICISTS. That is a huge red flag. If you had fake UFOs, you would have a puzzle for physics: What is the science?
A true recovered interstellar craft would be like LHC or LIGO data: potential scientific data for physics beyond the Standard Model and General Relativity.
But if the crafts are fake, you would be crazy to let the A-team physicists near them. It would blow up in your face.
So my ignorant question is this: are there stories of building fake UFOs for sites in Nevada? Ohio? Are there fake retrieval teams? To what extent does faking military equipment spill into faking a UFOgasm for decades?
Because there are too many very similar craft stories.
So, at this point, the stories of craft kept at secret locations is most likely to be true in my opinion. But it is also true that all the top physics talent that was working only semi-covertly on suspicious gravity projects left by the early 1970s. So any craft may be faked.
Either way, itâs a big deal. Everything changed in the early 70s. Itâs impossible to say how much. The moment the Mansfield amendment came in, physics began to stagnate. And âQuantum Gravityâ destroyed our culture of science. We donât even whisper about its âAnti-Gravityâ origin.
Note Added: many readers are making wild inferences about me talking about flying fakes. I was very clear that this was about apparent crafts on the ground and in Hangars in Nevada, Ohio & elsewhere.
Wild or bad inference patterns will get you blocked. I donât have time. Thx.
