Is it strange that there are exactly the same number of superstring theories as there are known quarks?
And how about all their supersymmetric partners.. the squarks?Originally posted by Terry Giblin
To be absolutely correct, in addition to the antiquarks, each six quarks also has three different colours, 6 x 2 x 3 = 36!

Monique you mentioned squarks – is this another name for superparticle or sparticle or for a mediator particle?
Photon, electron and sparticle or lepton, quark and squarks – no argument from me.
Super-string theories propose that the fundamental building blocks of the universe are tiny strings, while M-theory proposes that the universe is made up of 11 dimensions and that these strings are actually higher-dimensional objects called branes.
Both super-string theories and M-theory attempt to unify the fundamental forces of the universe, including gravity, through the concept of string theory. This theory suggests that everything in the universe is made up of tiny strings vibrating at different frequencies, which can explain both the particle-like behavior of matter and the wave-like behavior of energy.
The five super-string theories, also known as Type I, Type IIA, Type IIB, Heterotic-O, and Heterotic-E, are all mathematically consistent and each describes a different version of the fundamental strings. This suggests that they may all be different aspects of a single, overarching theory.
M-theory is considered to be a unifying theory that encompasses all five super-string theories. It extends the idea of strings to higher-dimensional objects called branes, which allows for the possibility of multiple dimensions and can potentially reconcile the differences between the five theories.
Currently, there is no direct experimental evidence for super-string theories or M-theory. However, some predictions of these theories, such as the existence of extra dimensions, may potentially be tested through high-energy particle accelerators. Additionally, observations of the cosmic microwave background radiation may provide indirect evidence for these theories.
