On Casimir Force - Scholarpedia i did find the following:
So i guess nobody knows how real ZPE is. :confused:
The casimir force is about 8 mN/mē for a plate distance of 1http://www.thephysicsforum.com/vlatex/pics/3_c9faf6ead2cd2c2187bd943488de1d0a.pngm, and about 5N/mē for a distance of 200nm.
This does not...
Unfortunately i can not read that link.
I also thought that the existence of ZPE was without doubt. But than i read that it could also be seen as a mathematical bookkeeping trick for explaining...
I understood that there is a huge difference between the measured value of the cosmological constant (almost zero) and the quantum field energy (when cut-off at planck length: about 1E120...
As an autodidact i always though that the Casimir effect showed the existence for zero point energy in empty space without doubt.
But then i read more about it and it looked like the existence the...
Sounds logical, so unless someone has another answer i would think that's it.
One possible configuration would be a series of parallel plates next to eachother:
phase [pi] 0 .33 .66 1 1.33 1.66 0 .33

For a far a i know it is the E-field that stores the energy in a capacitor (except that in high-Q materials the energy storage is a mix of chemical and E-field energy).
So lets assume a vacuum gap...
Suppose you have 2 parallel opposite charged metal plates, would the energy stored in the electric field have any momentum?
I suppose it does because:
E=mcē
So, when we assume E is the...
The "charge in the electromagnetic field" is exact the example that led to this topic in the first place.
For example: take a charged body A and an uncharged body B seperated by some distance d....
If i interprete Gravitational wave - Wikipedia, the free encyclopedia correct, a rotating symetric dumbell does indeed not radiate gravitational waves, but when it is asymetric it does.
I did make a small program to calculate the gravitational field of one accelerated mass (using dētau/dx). It nicely showed the expected result: a gravitational field slightly directed in the opposite...
That sounds quite logic. You're probably right.
However, when the action and reaction mass are sufficient seperated and the distance to 1 mass is much smaller than to the other, i would expect that...
In advance i would like to apologise for my poor english and the fact i am just a layman in physics, so i hope i get the terminology right.
The reason for this post is that i wondered how the...
