zero origin of length

[AntonioLao]

what is the meaning of zero length? Or zero dimension?

[Mr. Nobody]

A point or the intersection of (2) one dimensional lines or 3 (2) dimensional surfaces. But does it exist in nature? No, its a simplification or a mathematical model, an approach to describe an ideal concept.
The point is the beginning of an idea, like 0. 0 and points are more than nothing.
It also represents the confirmation of a presence, location in space. You are here.

[Guille]

I agree with Mr.Nobody. Although a point is something, it is not a thing. It's hard to explain with language.

But I believe real points don't exist, and can't exist. It is a sort of illusion.

when two protons are separated by less than 1 fermi, 10^{-15} meter, the strong force is repulsive.

[Guille]

when two protons are separated by less than 1 fermi, 10^{-15} meter, the strong force is repulsive.

Is this neccesarilly impplied, or ould it be that it is the inreaction between the strong force and any other force that has as prudct this repulsion?

I always wonder why physicists have gone into everything about forces, energy, matter, dimensions... But never have thought about a theory of the interaction between different forces, as if it we'ren't possible. In our day-to.day experience we see forces interactions, throughout our life the force that push us to keep up with life is supported by the force of happiness and satisfaction but fighted by other forces.

[AntonioLao]

the nonexistence of di-proton (molecular proton) is evidence that strong force is repulsive at distances less than 1 fermi. The nucleus of hydrogen has 1 proton but the nucleus of the next element helium has 2 protons, for this to be possible, there are 2 neutrons in the helium nucleus. Again this shows that proton-proton systems cannot exist in nature these must be balanced by equal number or more of neutrons.

[Guille]

And then we can write the following equations to describe it:

1<Fermi<3<-->Strong Force atractive
3<Fermi<-->Strong Force Zero
Fermi<1<-->Strong Force Repulsive

We can see that when the force is atractive it is in the middle of when it is zero and when it is repulsive. Therefore, Proton's strong force charge covers an atracton of radius r, and when two equal strong force charges just "touch" the other's end, they repel. and this is fermi distance. and when the two strong force charges are between 1 and 3, the they attract because they have a secondary force. So basically I mean that there are two strong forces, one is direct and charged (particle), and the other one is indirect, consequence (wave). I think this matches what Force05's TOE is about.

1 fermi is about 10 light-year ratio to the Planck length of 10^{-35} meter.

[Guille]

1 fermi is about 10 light-year ratio to the Planck length of 10^{-35} meter.

Is there a fermi equivalent of time (as there is a planck time)?

[AntonioLao]

Is there a fermi equivalent of time (as there is a planck time)?

If my calculation is correct Fermi time is 3.3333X10^{-22} second.
