The dipole creates 2 fields of 1/r². One q/r² and one -q/(r+d)²
Where d is the distance between the two charges.
F= q/r² - q/(r+d)²
You can see that when d = 0 then F = 0.
And that at any distance F < q/r²
F= ( q*(r+d)² - q*r² ) / ( r²*(r+d)² ) =
q * ( (r+d)² - r²) / ( r²*(r+d)² ) =
q * ( r² + d*r + d² - r² ) / ( r²*(r+d)² ) =
q * ( d*r + d² ) / ( r²*(r+d)² )
For d << r
F = q * ( d*r ) / ( r²*r² )
= q * ( d ) / ( r³ )
This is what querius is saying.
We can get the field close to 1/r² again by making the distance d very large.
This is also possible by chaining a lot of dipoles together. The distance d becomes
the largest distance between the dipoles.
For d >> r
F = q * ( d² ) / ( r²*d² )
F = q / r²
This is the equation that is used by Bengt it seems.
Also Siggy's examples show cases where d is relatively large to r
This is all without any shielding.
Siggy's example shows a sphere with one dipole on the inside and one dipole on the outside.
It seems to suggest that the inside is shielded off from the outside.
I don't think that shielding works that way. As I understand shielding adds a dipole in the system,
instead of completely blocking the field. So shielding can not create a monopole from a dipole.
A dipole gravity would only work when the charges are separated over a long distance.
Siggy suggests that the shape of the distribution is also important.
To make this all work in the solar system, I have to create a charge-distribution that reaches all
the way to the (probably non-existing) Oort cloud. The shape might be like that of a disk.
While I think that the sun creates a large electron-charge distribution in the solar system, I do not think
that it is responsible for the gravity system. Gravity is also not sensitive to shielding or electrical charge.
In Thornhill's other videos, he states there are sub-particles (of known subatomic particles) responsible
for the gravity. This is a much better choice, since we know for example that neutrinos are responsible for transporting mass. Neutrinos can not be detected directly, even in massive numbers.
Something similar might be responsible for gravity too. That is how I understand it.
In the latest video Thornhill even describes connection-lines between particles. This model is slightly different,
but can indeed be used to model all known interactions between particles. The connection-lines can
be related to particles, just as gluons that connect quarks.
An other model that might be considered is some sort of dynamic aether. Dynamic aether is moving with gravity and could be responsible for gravity as well.
Looking at the solar system, we clearly have a 1/r² force/acceleration that keeps the planets in orbit.
On the level of galaxies this force is different. We see 1/r forces/acceleration instead.
This force even creates spiral patterns, unlike the solar gravity.
Adding invisible matter to to the system does not change the 1/r relationship.
Polar forces like electromagnetism do create spirals and can create a 1/r accelerations.
As I understand it, this might be possible when the whole galaxy is different in polarity from its halo,
and when strong magnetic-like forces are included. Magnetic forces increase when charged matter is moving.
It might be interesting to see how these distribution is organized, whatever model of gravity you are using.
I think that it is interesting to find a common cause of both electromagnetism and gravity. That is a problem that even mainstream science is trying to solve.
