Implications of M-Theory on the correctness of String Theory
So we know that there are 5 types of string theories (Type 1, Type IIA, Type IIB, $SO(32)$ heterotic, and $E_8 \times E_8$ heterotic). It was shown that these 5 types are just limits of something ...

Regarding a possible duality between (2+1)D gravity and Chern-Simons Theory
Is there a duality between (2+1)D gravity and Chern-Simons Theory? Or they merely have related features? If so, of which type and why?

Bern-Carrasco-Johansson (BCJ) Double Copy and Color-Kinematic duality
According to the wikipedia page on Strong Gravity, the theory is considered "non-mainstream", but from what I can gather there have been some very interesting progress and results since it ...

String length vs. UV completion
In string theory, we have a fundamental length $l_s$. From T-duality, we expect a duality between UV and IR; a length smaller than $l_s$ is regarded as a length greater than $l_s$. We do not see any ...

What is really M-theory? (non-pertubatively)
I don´t really understand what M-theory is supposed to be. Going beyond the dualities relating different string theories (for example the common $11-D$ limit of IIA and $E_{8}\times E_{8}$) I don't ...

How does holographic duality work?
In holographic theories about the universe, the one being in the boundary of the space, takes information of the higher dimensional universe, so, two different theories can describe the two universes.

Has anyone explored a possible duality between quantum gravity and statistical mechanics?
There is a well known duality between quantum mechanics in D dimensions and classical statistical mechanics in D+1 dimensions. Specifically, the Euclidean version of the path integral in D dimensions ...

Holographic principle and holograms
Holographic principle or Maldacena's duality is a theory that says that the volume of space can be described by just looking the information encoded on a boundary to the region of that space.

Does the existence of dualities imply a more fundamental structure?
I was wondering if the existence of some kind of duality in physics always implies the existence of some underlying more fundamental structure/concept?
Let me give a few example from history:
