A Little As To The M-Theory Idea

Superstrings tend to exist in orbifolds.  Orbifolds tend to exist in orbifold eigensets.
E(8)XE(8) superstrings are the fabric that binds orbifolds into orbifold eigensets.
The reason that superstrings appear to exist as membranes that act in unison is because of a number of reasons.
1)  As said before, superstrings tend to exis in orbifolds, and orbifolds are the membrane-source of all substringular phenomena that act as a group besides superstrings And phenomena that are smaller than superstrings.

                
2)  Orbifolds tend to exist in orbifold eigensets, and, such eigensets exist in as a membrane-like phenomena as well.
                                         
3)  Superstrings that exist in any tense of superconformal invariance exist -- while these are in superconformal invariance -- in a general vibrational locus, when taken individually, so as to form via their corresponding Gliossi-Sherk-Olive ghosts, a pattern that represenst a membrane-based appearance.  If it wasn't for the existence of ghost anomalies, their would be no substance where as to form the dilatons and dilatinos that are necessary for the ensuing formation of gravitons and gravitinos.  Gravitons and gravitinos are the gravitational-type of superstrings that -- via the Ricci Action via the Rarita Structure -- allow for the existence of gravity.

4)  Orbifolds and orbifold eigensets that exist in any form of conformal invariance form a multiplicit array of Gliossi-Sherk-Olive membrane-based ghost patterns that bear activities that excentuate the existence of that phenomena that interconnect the orbifolds, and E(8)XE(8) superstrings are that phenomena that interconnect the orbifolds into orbifold eigensets so that phenomena that are significantly larger than superstrings may act together as a group in the form of normally detectable subatomic phenomena.

5)  The activity of E(8)XE(8) superstrings indirectly cause the motion of E(6)XE(6) strings in such a fashion so that these later mentioned hadrons may pluck the second-ordered light-cone-gauge eigenstates like a harp so that vibration eigenstates known of as Schwinger Indices may propagate along the Rarita Structure so that there may be a relationship between gravitational particles and discrete units of energy.  Without the prior implied Ricci Action taken multiplicitly throught space and time, gravity would not have a chance to be kinematic upon superstrings that are discrete units of energy.

6)  The exchange between Gliossi-Sherk-Olive ghost eigenstates and other ghost eigenstates that are on the Real Reimmanian Plane eigenconiaxials where superstrings and their corresponding Fadeev-Popov ghosts With the Neilson-Kollosh ghosts that exist in the regions where the gravitational particles work via the Ricci Action eigenstates so as to allow for what would appear as a membranal interchange -- while certain ghost anomalies are perturbated into positive and negative norm-states -- that makes it appear that the basic "substance" that forms subatomic phenomena is to be membranal phenomena.  Yet, if it wasn't for the existence of superstrings, orbifolds would have no internal-based function, and, orbifold eigenstates would have no internal-based function.

A Little About What Caused What

If it wasn't for the Logos, the Higgs Action would never have been activated to begin to create a discrete reality out of the Big-Bang.          
If it wasn't for the Higgs Action, metric-gauge would never have been created to allow for the soon to be created superstrings to act as discrete units of energy permittivity -- as well as to allow for the soon to be created Fadeev-Popov-Traces to act as discrete units of energy impedance.
If it wasn't for the kinematic multiplicit redistributions of superstrings, there would be no ghost anomalies.
If it wasn't for ghost anomalies, there would be no Njenhuisly placed gravitational particles.
If it wasn't for Njenhuisly placed gravitational particles, the Rarita Structure would serve no purpose, and the Ricci Action would never take effect.
If the Ricci Action never took effect, gravity would never be attainable, and mass would never be able to be attained.                       
If there was never any mass, the perpetuation of electromagnetic energy would not be sustainable -- since soon after the Big-Bang happened, electrons dropping back-and-forth an energy level is what has subsequent to then been the activity that releases discrete energy known as photons, or, in other words, since soon after the Big-Bang happened, it has taken a type of mass known as an electron in order for light to be perpetuated and sustained.
If it wasn't for electromagnetic energy, the absence of light would cause mass to have no relativity and also no ability to have any heat.
If it wasn't for heat, mass would have no vibration, and thus mass would not be sustainable.
If it wasn't for phenomena to differentiate relative to light, there would be no time, length, nor mass relationships.
If it wasn't for there to be a relationship of mass toward its environment -- mass, heat, gravity, and motion period would fly apart into nothingness.
Yet, certain realities are the way that they are period. -- Just like basic math is just a fact of reality that can not be changed.
Since reality has been perpetuated from soon after the Big-Bang, the activity of Schwinger Indices upon the Rarita Structure has been what causes the Wick Action that causes the Landau-Gisner-Action to cause the Suskind-Fischler-Mechanism to have a leverage to allow the Higgs Action to move the Klein Bottle so that Gaussian Transformations are possible so that energies existence may be sustainable so that reality may continue to exist.
