I guess you are not familiar with Brian Greene then?  Would you lend yourself to crackpottery?  Why do you expect other physicists to commit crackpottery?

What is the equation for a string field and I will give you a pass on this?

String field theory

String field theories come in a number of varieties depending on which type of string is second quantized: Open string field theories describe the scattering of open strings, closed string field theories describe closed strings, while open-closed string field theories include both open and closed strings.

Quote

In addition, depending on the method used to fix the worldsheet diffeomorphisms and conformal transformations in the original free string theory, the resulting string field theories can be very different. Using light cone gauge, yields light-cone string field theories whereas using BRST quantization, one finds covariant string field theories. There are also hybrid string field theories, known as covariantized light-cone string field theories which use elements of both light-cone and BRST gauge-fixed string field theories.[5]

Quote

A final form of string field theory, known as background independent open string field theory, takes a very different form; instead of second quantizing the worldsheet string theory, it second quantizes the space of two-dimensional quantum field theories.

It appears then that there is no single field equation that describes all fields.

I do like the concept of Causal Dynamical Triangulation (CDT), proposed by Renate Loll et al

Causal dynamical triangulation (abbreviated as CDT) theorized by Renate Loll, Jan Ambjørn and Jerzy Jurkiewicz, and popularized by Fotini Markopoulou and Lee Smolin, is an approach to quantum gravity that like loop quantum gravity is background independent.

This means that it does not assume any pre-existing arena (dimensional space), but rather attempts to show how the spacetime fabric itself evolves.

Quote

There is evidence [1] that at large scales CDT approximates the familiar 4-dimensional spacetime, but shows spacetime to be 2-dimensional near the Planck scale, and reveals a fractal structure on slices of constant time. These interesting results agree with the findings of Lauscher and Reuter, who use an approach called Quantum Einstein Gravity, and with other recent theoretical work.

"String field theory was to be the theory of interacting strings. To describe interacting objects, you need a quantity called the Lagrangian (that's L in Kaku's equation). ... Now Michio Kaku's equation is clear. It is the Lagrangian describing the interaction of strings."

I hope this has humbled you, maybe you don't know as much as you think you know, now watch the lectures.

Thank you for that explanation, I have run across Kaku's equation but have not yet studied the narrative. 

As to in-depth knowledge of string theory, as an ex-musician, I never claimed anything but interest in the subject. I will watch the lectures unless you piss me off with unnecessary ad hominem .  You will find me quite humble, but I don't like to be humiliated, OK?

Do you want a biscuit?

 

P.S. hahahaha, I would pay money to see the look on your face when you read this, now go watch the lectures.
