Casimir effect - Does it fit? Or NOT?

In summary, the Casimir effect is a real phenomenon that has been proven through numerous experiments. It is a result of electromagnetic field quantization in various geometries and is related to the four fundamental forces in physics. The Casimir effect can also be manipulated to potentially reduce friction in nano-machines. Despite some skepticism, the effect has been measured to have a pressure equivalent to 1 atmosphere over a distance of 10 nanometers.

I just heard about the Casimir effect:
http://en.wikipedia.org/wiki/Kashmir_effect

Is this for real? Or is it just speculation?
If it's real, then how in the name of science does it fit into the four fundamental forces?!
http://hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html

I think it's just a fancy name for friction. I think friction is an example of electromagnetic force, same
as the pressure of standing on the floor. But I could be wrong! The pressure of standing on the floor could be a result of gravity! So which is it? EM or Gravity ? Or both?! We can't even talk about the Casimir effect (if it even exists) until we can clear up something as simple as standing on the floor. :!)

Casimir effect is very real and there have been numerious experiments attesting the existence of that macroscopic force. That's not something new, it can be interesting, but it's a just a mere effect of EM field quantization in various geometries. As for the 4 forces, well they go hand in hand, since the theory of 4 forces is based on (gauge) field quantization which also explains the existence of the Casimir force.

Here is page by Ulf Leonhardt explaining how manipulating the Casimir effect may allow advances in the reduction of friction in nano-machines.

the wiki page must be in error, there is no way that this could be true:

Indeed at separations of 10 nm — about a hundred times the typical size of an atom — the Casimir effect produces the equivalent of 1 atmosphere of pressure (101.3 kPa)

1 atm over a separation as large as 100 angstoms? no way
 

What is the Casimir effect?

The Casimir effect is a physical phenomenon in which two uncharged plates, positioned very close together in a vacuum, experience an attractive force due to quantum fluctuations in the vacuum energy.

What is the cause of the Casimir effect?

The Casimir effect is caused by the presence of virtual particles in the vacuum, which constantly pop in and out of existence. These particles create a force between the plates, resulting in the Casimir effect.

Does the Casimir effect fit with our current understanding of physics?

Yes, the Casimir effect is well-supported by the theory of quantum electrodynamics, which describes the behavior of electromagnetic fields at the quantum level.

Are there any practical applications of the Casimir effect?

Yes, the Casimir effect has been utilized in the development of tiny mechanical devices and in the study of nanotechnology.

Is there any evidence that the Casimir effect does not exist?

No, there is currently no evidence to suggest that the Casimir effect does not exist. It has been observed and studied in numerous experiments, and its effects can be accurately predicted by the theory of quantum electrodynamics.
