GRAVITY EXPLAINED
The Strength of Gravity, the Feeble Apparent
Gravity is a universal force—for any body:
The force felt by a body is mass proportional;
Yet, the acceleration that’s felt is the inverse!
This coincidence removes all mass dependence.
(Einstein transcended this amazing “coincidental” race
By bodies going straight through curved space.)
Gravity might be derived from the fundamentals,
The byproduct of a small residual after cancelations
Of opposite electric or color charges, and more.
Why then is gravity universal, for its sources are not?
Perhaps the appearance of feebleness is deceptive
Since protons and neutrons are but lightweights.
But why are they so light? Their mass is a compromise
Between a disturbance energy and its cancellation.
The quarks’ color charge disturbs gluons around them,
Small at first,
But larger growing farther from the quark.
These disturbances cost energy, but how to cancel them?
With an anti-quark
Or two complementarily colored quarks.
But the qualifying quarks can’t sit atop the originals,
For quarks have no definite position,
Just a wave function,
And they can’t be localized to a small spread of position,
For this requires a larger energy—so forget nullification.
The compromise is that some residual energy amounts
From the not-completely-canceled
Gluon field disturbances
And from the not-completely-canceled quark positionings,
Thus the proton mass from m=E/cc,
With this tricky element
Of how the gluon disturbance field grows with distance.
(The residual strong energy from color charge also binds
The protons and neutrons in the atomic nucleus;
The electromagnetic electron/nuclei charge residuals
Bind atoms into molecules and molecules into materials.)
Asymptotic freedom is a subtle feedback effect
From virtual particles antiscreening the color charge.
This antiscreening builds up gradually,
Especially at first,
Then proceeds more quickly,
Building upon each building.
(Whereas,
Screening happens for electrically charged particles,
Being such as a positive charge
Attracts a negative virtual cloud.)
Thus, at first, since it’s so slow to build, the pressure
To localize the nullifying quarks is quite mild as well.
Thus, there’s no need to very strictly localize and
So the energies are small; so then is the proton mass.
This is the lightness of being.
