Would forces such as the Casimir effect fall under this heading? Btyner 21:08, 23 July 2006 (UTC)[reply]

No. Traditionally only forces that "couples to" (are proportional tp) mass-energy are considered are counted as "difth force". The Casimir effect is an important difficuly in the short range experiments looking for a fifth force. --Pjacobi 22:34, 6 October 2006 (UTC)[reply]

Experimental evidence?

Randell Mills has published a paper that purportedly describes experimental confirmation of his theory regarding the fifth force anti-gravitational effect of so-called hyperbolic electrons. The experimental setup seems fairly straight forward - create hyperbolic electrons by shooting a beam of free electrons of the correct energy through a perpendicular beam of neutral atoms (e.g. He, Ne, Ar, etc.). He then measures the upward (anti-gravitational) deflection of the electrons by the ratio of current densities at two grounded electrode plates, one above and one below the electron beam, both positioned about 100mm behind the atomic beam. He varies the electron energy and sees deflectional peaks that correspond, roughly, to quantum modes predicted by his theory. This seems like a pretty interesting phenomena - particularly because it should be easy to replicate. Anyone else think this is worth mentioning on this page?

Michael Martin Nieto (of the Greenland experiment) suggested such an experiment as a means of testing the Fifth Force over metre length scales. I know he was trying to get an experiment together; unfortunately I did not hear what became of it (I am not a physicist; my interest was in measuring ice thickness). --APRCooper (talk) 16:20, 24 June 2009 (UTC)[reply]

Greenland experiment

I have added information about the Greenland experiment to determine Big G. I also reformatted the references to the conventional standard. I may not have correctly located the references in the text.

An aside, that would violate NPOV and so isn't for the main article, but the Greenland experiment, although it COULD be explained by geological bodies, requires such an extreme geology that it seems unlikely! --APRCooper (talk) 16:17, 24 June 2009 (UTC)[reply]
