Casimir Force pushes 2 metal plates together.
Finally proven in 2003 to within 5% of values predicted
by Casimir back in 1948.
My theory is that the "abnormal space" between
the plates thins out the miniscus of the virtual particle sea by a factor
proportional to how close the plates are braced. an electron is free
to twist partially out of the normal space by the low density of the
miniscus on either side of it. these membranes represent past and future
direction and will soon be traveled just like regular space using hydrinos
or any molecules that twist then get locked by forming covalent bonds
The Casimir effect
Based on the idea that the 'vacuum' of space is actually a seething foam of quantum fluctuations of different frequencies, Casimir proposed that if two electrically conducting, but uncharged parallel plates were mounted a small distance apart in a vacuum, they would tend to be drawn together. An important point is that the plates carry no electrical charge so that any interaction between the plates must come from some other source.
Casimir predicted the value of this force and in 1996 Steve K Lamoreaux, then at Washington University, measured the force to within an accuracy of five per cent of Casimir's prediction for that configuration of plate separation and geometry.
Over the range measured the force is directly proportional to the area of the plates and inversely proportional to the fourth power of their separation.
As far as I know only a very limited number of experiments have been carried out over a very limited range of plate separations, so it is only possible to conclude that the force is inversely proportional to the fourth power of the plate separation for a very limited range of separations. It may be possible to show that, depending on the shape of the quantum fluctuation, the force may appear to be proportional to the inverse fourth power of the separation at one distance but proportional to some other ratio at a greater or smaller distance.

Large scale Casimir effects
In the 8 June 1996 issue of New Scientist magazine an article entitled Physics unpicks a sailor's yarn, by Paul Guinnessy, reported on the phenomena noticed in the days of the square rigged sailing ships that, under certain sea conditions, ships lying close together would be mysteriously drawn together until there was a danger of their riggings clashing.
Only conditions of practically no wind but with waves on the sea would result in the phenomenon occurring and then the force was so small that the ships could be pulled out of danger by rowing boats.
So it seems that the Casimir effect applies at levels from sub-nuclear to at least the human scale. I believe that future experiments will show that the Casimir effect operates at all levels from sub-nuclear to cosmological scales.
