Grand Unification

[Johnny5]

I have a question.

What standard things do you think the final 'model' of physics should explain.

 

Right now there are thousands of experiments discovering the tiniest minutia, but no mathematical theory is going to be able to explain one billion bits of minute experimental data.

 

I can sort of start this off.

 

1. magnetic moment of proton

2. magnetic moment of neutron

3. magnetic moment of electron

4. g factors

5. Why the nuclear force range is what it is.

6. Fine structure constant.

7. Formula for gravity

8. Show how the fundamental constants of nature are related.

9. Equation of motion for particles

10. Explain masses of elementary particles

11. Explain superconductivity

 

etc

 

You get the idea.

Here is the question again...

 

What things must the final supertheory of physics explain?

[[Tycho?]]

It would have to explain the fundamental workings of the universe, from which all other phenomenon can be derived. If only explained a few things it wouldn't be very final.

[Severian]

1. A finite quantum description of gravity.

2. A unification of the 3 non-gravity forces into one Yang-Mills theory.

3. A unification of 2 with gravity (supergravity?)

4. A solution to the hierarchy problem.

5. A solution to the baryon asymmetry problem.

6. Explain why masses have the values they have (including neutrinos).

7. A mechanism of electroweak symmetry breaking.

8. An explanation of why there are 3 generations.

9. A solution to the strong CP problem.

10. Don't screw up anything which the Standard Model already correctly predicts.

 

I am sure there are more but these are the most important...

This is the kind of answer I wanted.

 

Everyone is talking about quantum gravity these days, I talked to a Ms Palmer at the European Journal of physics, and she told me to work on that.

 

Mmmm what the hell is quantum gravity?

...

 

What does this refer to?

from http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/particle_zoo.html

 

In the quark model, there are only 12 elementary particles, which appear in three "generations." The first generation consists of the up quark, the down quark, the electron, and the electron neutrino.* (Each of these also has an associated antiparticle.) These particles make up all of the ordinary matter we see around us.* There are two other generations, which are essentially the same, but with heavier particles.* The second consists of the charm quark, the strange quark, the muon, and the muon neutrino; and the third consists of the top quark, the bottom quark, the tau, and the tau neutrino. These three generations are sometimes called the "electron family", the "muon family", and the "tau family."

to sumerize or unify all of the matter or energy in the universe, you might want to have a basic idea of the four fundamental powers. i too am working on this. i found some type of answer..............................i'm not trying to brag if that's what people are thinking. if you want i can give you another rout to go other than the four fundamental powers. i've already taken this route. e-mail me for the details. i would love to help you. a lot of people have helped me on this site. before i forget to tell you................. i can only give you leads. but those will help
