Five Super-string theories and one M-Theory = 6

In summary, there are the same number of superstring theories as there are known quarks. Each quark has an antiparticle, making 12. Even if you only count 6, they are 6 things of the same kind. However, there is a sixth basic theory included in M-Theory, namely eleven dimensional supergravity or SUGR.

Is it strange that there are exactly the same number of superstring theories as there are known quarks?

1. Every quark has an antiparticle, making 12.
2. Even if you only count 6, they are 6 things of the same kind. But M-theory is not a string theory like the other 5, but a blanket theory that includes them. It's like saying we have three sexes, women, men, and people.

To be absolutely correct, in addition to the antiquarks, each six quarks also has three different colours, 6 x 2 x 3 = 36!

I consider the three unexplained three different colours of quarks is due to the quark dimension being polarized in the x,y,z dimensions.

For every reaction there is an opposite and equal reaction, quark-antiquark.

As I said there are 6 superstring theories, 5 with 10 Dimensions and the M-Theory with 11 Dimensions.

Only from observing in an extra dimension can you truly see the beauty of the dimensions you are observing.

Only by considering what came before or will come after men and woman, only then will you think of people as a third choice, you have to take into account the time dimension.

and SUGR makes six

However, there is a sixth basic theory included in M-Theory, namely eleven dimensional supergravity or SUGR for short.

And how about all their supersymmetric partners.. the squarks?

At the present time, those are just hypothetical. And even in the super theories, they have to be "hidden" because we sure don't see them.

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.

A more interesting question would be to try and ignore spin, for one second, and quickly redraw the Standard model chart based on an alternative sequencing, squarks and all.

Don't listen to the "spin" merchant's, pretend you had not heard of spin - trust me its easy.

sleptons and squarks are bosonic superpartners to the fermionic particles, leptons and quarks. Photinos, winos, and gluinos are the fermionic superpartners of the bosons, photon, W-particles, and gluons. The naming convention, which is maybe overcute, should be obvious.

Of course you can't ignore spin and have all these particles.

It's perfectly legal, and not at all shocking, to ignore spin for the moment and look for symmetries that aren't spin dependent.
 

1. What is the difference between super-string theories and M-theory?

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.

2. How do these theories attempt to reconcile quantum mechanics and general relativity?

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.

3. What is the significance of there being five super-string theories?

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.

4. What is the role of the M-theory in the unification of these theories?

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.

5. Are there any experimental tests or evidence for these 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.
