Re: Thornhill's gravity model
NO, force is only electric force. The other three forces are variants of electromagnetic force.Bengt Nyman wrote:You are wrong, look again. There are four forces in total, two attract (+- and -+) and two repel (++ and --).Zyxzevn wrote: ...
What seems to be gravity in outer space is electromagnetic force and there is repulsion force. Gravity on the ground is a very complicated mechanism and is related to rotation and magnetic field. For details, please look at my website.

ja7tdo,
Postings here should be on topic. This subject of this thread is dipole gravity.

Re: Thornhill's gravity model
Yes, but you are also posting brief and scattered thoughts on half a dozen other subjects. My advice to you would be to learn all present, mainstream physics that you can, then concentrate on one subject at a time and follow your intuition to try to advance that subject. There is no lack of opportunities in physics because of the complexity of reality compared to the limited comprehension of the human mind.ja7tdo wrote: ... I am posting topics along dipole gravity.

Re: Thornhill's gravity model
Ok, I missed the one on the top in your picture.Bengt Nyman wrote:There are four forces in total, two attract (+- and -+) and two repel (++ and --).Zyxzevn wrote: ...
But do you know how much force that gives, related to distance R?
Let me show that for you.
I start with with 2 charges:
(+)---------<-R->-------(-)
It gives force:
F= k*q*q/R^2 Coulomb's law
Let me use Siggy's quote here:
Now what happens if you put a dipole at one side?Siggy_G wrote: .. it is is spherical, also called a divergent field, with an inverse square fall off .
(-)-(+)--------<-R->-------(-)
We have two forces:
F(+-)= k*q*q/R^2 (attracting force)
F(--)= k*q*q/(R+d)^2 (repelling force)
The charge on the right will get both forces, so we have to subtract the forces.
F(1 dipole)= F(+-) - F(--) = k*q*q* [ d( d+2*R)/(R*R*d*d+ R^4) ]
Wolfram Alpha link
look: we now have R^1 on the top and R^4 on the bottom.
When d is much smaller than R, which is almost always true,
the R becomes dominant, and we get.....
F(1 dipole)= k*q*q*[ d*2*R/ (R^4) ]= k*q*q*[ d*2/ R^3 ]
Of attractive force (as long the charges are in this order)
Look in the formula:
We got a R^3 there, not a R^2 or R^4 any more.
The d^2 is also in the top, so if d is very small, the attraction is very small too.
If d would be zero, we would have no force, which is logical.
And if d<0 then the force will be repelling, also logical.
Now what if we have two dipoles instead of the charge at the right side.
(-)-(+)--------<-R->-------(-)-(+)
For the dipole on the right: One charge will get attracted and one will get repelled.
Because I assume the dipoles are connected, we have to add the forces for both charges.
As Bengt already stated, we have 4 forces.
F(+-) = k*q*q/R^2
F(++) = k*q*q/(R+d)^2
F(--) = k*q*q/(R+d)^2
F(-+)= k*q*q/(R+2*d)^2
So the force on the right dipole is:
F= F(+-) - F(++) - F(--) + F(-+)
F= k*q*q* [ 4d^4 + 12 d^3*R+ 6 d^2*R^2 ]/[ R^2*(d+ R)^2(2d+R)^2 ]
Or F= k*q² [ 4d^4 + 12d³R+ 6d²R² ]/[ R²(d+ R)²*(2d+R)² ]
Wolfram Alpha link
Now we have R^2 divided by R^6
So when we assume the normal situation in which d is significantly bigger than R we get:
F(dipole)= k*q² [ 6d²R² ]/[ R²( R)²*(R)² ]
Which gives:
F(dipole) = k*q*q* [ 6*d^2 / R^4 ]
So as I stated the force between 2 dipoles is indeed 1/R^4
And with a small d it gets very small due to the d^2
So with this basic maths explanation I have shown that the force between dipole and any charge
is always in the order of 1/R^3
and the force between two dipoles is in the order of 1/R^4
This makes dipoles worthless as a replacement of gravity,
which in the solar system works with the force of 1/R^2
So I look at dipole.se what in the heck is wrong, where I see that
Bengt has no distance between the dipoles in his gravity, but calculates the
force when dipoles are next to each other.
So instead of gravity bengt calculates forces similar to the vandewaals-force.
See: https://en.wikipedia.org/wiki/Van_der_Waals_force
Or electrostatic force. See: https://en.wikipedia.org/wiki/Electrostatics
This force can indeed overcome gravity, as we can see with water drops
that sting to surfaces. Or insects that stick on the ceiling.
The funny thing, is that they still only work at close distances, as
anyone who has seen drops falling from a glass can confirm.
I think this picture says enough:

Re: Thornhill's gravity model
How very convenient; dipole gravity permeates everything and is therefore impossible to shield or even detect. Yet you are certain it is there.Siggy_G wrote: The presumably shielding objects in some thought experiments will merely take part in this. It is not unlikely though, that certain material types of presumably shielding objects will create small offsets or fluctations in measured weight of internal free-to-move objects. However, weights and voltmeters will become polarized in the same manner as what it's supposed to measure, so this may be hard detect.
Are you just making this stuff up for fun?

NEVER use 1/r^3 or 1/r^4, they are special case approximations.Zyxzevn wrote:Ok, I missed the one on the top in your picture.Bengt Nyman wrote:There are four forces in total, two attract (+- and -+) and two repel (++ and --).Zyxzevn wrote: ...
ALWAYS go back to each individual charge and use Coulombs Law with 1/r^2 on ALL vectors involved, because Coulombs Law ALWAYS holds true.
The dipole to dipole forces are extremely small, on the order of 10^-18 of the charge to charge forces, so the slightest approximation totally invalidates your calculations.

Re: Thornhill's gravity model
what about the original position of the dipole?
the problem i have with most of these solutions is that there is no accounting for the stream. The stream is the default condition. You can only overcome it. You cant reverse or negate it.

Re: Thornhill's gravity model
Finding and measuring the inner workings of gravity has been a challenge in physics till this day, whether it is hypothetical warped space, gravitons or other proposals. It is mostly the effect of gravity that can be measured, and even that isn't settled science. It is a reason anti-gravity is a (speculative) field of science and engineering, and a reason why anti-gravity devices aren't around yet. It's not easy to do an autopcy on an effect that is omnipresent and always additive, and figure out how to shield or counter it. Of course, further work and attempts must be done to achieve this.willendure wrote:How very convenient; dipole gravity permeates everything and is therefore impossible to shield or even detect.

The main criteria for a scientific model is that it is internally consistent and that one can empirically verify mechanisms from observation, extrapolation and interpolation. Dipole electrogravity, and its variants, is in my view scoring high in this regard.
A neat contribution to electrogravity theory has been done by the Norwegian physician Nils Rognerud. In his paper «Free fall of Elementary Particles» (1989/1994) he summarizes:
«We have seen how it is possible for two hydrogen atoms to generate a non-shieldable force of similar magnitude to gravity. This effect is due to the motional electric field produced by each atom. The dielectric hydrogen atoms will attract towards each other because of the divergent electric fields, produced by each atom. The dielectric force equation in Eq. (5.5) between two hydrogen atoms has a similar magnitude to that of gravity and follows the same inverse square law of force.»

Re: Thornhill's gravity model
Agreed. It has not been much talked about because of the complexity involved.Webbman wrote:what about the original position of the dipole? ...
All dipoles in all materials have original positions including original directions of their dipole axes dictated by atomic and molecular bonds in the material. This pattern can appear scattered or random.
If you start with the directions of these original dipole axes without the influence of gravity, and add the influence of external gravity you will see a slight shift in the direction of these axes, not all the way toward the new source of gravity but in favor of it. The amount of angular shift is the result of the ratio between the dipole moments exerted by internal bonds and the added dipole moments from external gravitation.

Re: Thornhill's gravity model
What about the fact that only the Earth's dipoles that are in the correct orientation, namely, the ones JUST under an object, are the only ones that can attract the object? All of the Earth's dipoles which form the hemisphere *diametrically opposite* a gravitating object will *repel* the object , not attract it.Siggy_G wrote:The main criteria for a scientific model is that it is internally consistent and that one can empirically verify mechanisms from observation, extrapolation and interpolation.

Honestly, this is getting to be like arguing about whether the earth is flat.
