The uniform actions of scientists inundated with strict and unflinching rules about the history of science, is exactly the kind of dogma that has lead String Theory to be the dominant research programme, whilst being relatively unfruitful in terms of what of its promises it has been able to deliver on.

String Theory posits that everything is composed of vibrating strings, that may close back on themselves, or curl, etc.

The assumption of superposition between states leads to a mathematical theory within which the equations that define states are linear in terms of the unknowns. The consequence of this is that people have attempted to establish analogies between this and classical systems, such as vibrating strings or membranes (Thoughts: it is super interesting that the fundamental objects of String Theory were around in Dirac))'s day).

So does String Theory subsume susy, or does susy just conveniently happen to fit within it?

The main theories are Supersymmetry, and String Theory.
