Ok.
How about a small dose of pity ?

Nomad will offer brief segments spaced far enough apart so participants can read, re-read, read again, have a smoke, kick the dog, call your therapist for an emergency session because your mind is exploding, then we can move on to another segment.
Thank you,

In the early years of the 20th century, the atom- long believed to be the smallest building-block of matter - was proven to consist of even smaller components called proton, neutron and electrons, which are known as subatomic particles. Beginning in the 1960s, other subatomic particles were discovered. In the 1980s, it was discovered that protons and neutrons (and other hadrons) are themselves made up of smaller particles called quarks.Quantum Theory is the set of rules that describes the interactions of these particles.

In the 1980s, a new mathematical model of theoretical physics called string theory emerged. It showed how all the particles, and all of the forms of energy in the universe, could be constructed by hypothetical one-dimensional "strings," infinitely small building-blocks that have only the dimension of length, but not height or width. Further, string theory suggested that the universe is made up of multiple dimensions. We are familiar with height, width, and length as three dimensional space, and time gives a total of four observable dimensions.

However, string theories supported the possibility of ten dimensions--the remaining 6 of which we can't detect directly. These "strings" vibrate in multiple dimensions, and depending on how they vibrate, they might be seen in 3-dimensional space as matter, light, or gravity. It is the vibration of the string which determines whether it appears to be matter or energy, and every form of matter or energy is the result of the vibration of strings.

String theory then ran into a problem. Another version of the equations was discovered. Then another, and then another. Eventually, there were five major string theories, all based on a 10-dimensional universe, and all of them appeared to be correct. Scientists were not comfortable with five seemingly contradictory sets of equations to describe the same thing.
In the mid 90s, a string theorist named Edward Witten of the Institute fo

Advanced Study and other important researchers considered that the five different versions of string theory might be describing the same thing seen from different perspectives. They proposed a unifying theory called "M Theory", in which the "M" is not specifically defined, but is generally understood to stand for "membrane." M-Theory brought all of the string theories together. It did this by asserting that strings are really 1-dimensional slices of a 2-dimensional membrane vibrating in 11-dimensional space.

I have a question .... what happens if your puddy tat eats all your string?

It's not even a theorem yet.
I'd give it some time for them to work the kinks out.

Theories are distinct from theorems: theorems are derived deductively from theories according to a formal system of rules, generally as a first step in testing or applying the theory in a concrete situation.
