This article in wired describes the efforts of some scientists to grapple with perhaps the biggest problem in modern physics - the total disconnect between General Relativity and Quantum Mechanics. Both are immensely successful theories - tested and confirmed to the limits of accuracy each within their respective domains. Both provide useful theoretical predictions, and in the case of the latter, are the basis for literally the entirety of our modern technology.
Yet, they don't match up. At all. What these intrepid researchers are doing is dropping a Bose-Einstein condensate - a gas so cold that it acts as a single particle, and thus behaves with all the quantum strangeness we've come to know and love. So far, they've just been doing proof-of-concept drops, to reassure themselves that the only thing acting on the condensate in the test capsule is gravity. Soon, though, they hope to start poking at relativity.
What interested me, aside from the general peachy-keenness of the idea, was the implications in terms of the whole plasma cosmology idea. The basic concept that Wal Thornhill, one of the plasma cosmology bigwigs, has outlined is this:
What is Gravity?
Sansbury argues that gravity is due to radially-orientated electrostatic dipoles inside the Earth's atomic nuclei, with the inner pole more positive and the outer pole more negative [36]. The force between any two aligned electrostatic dipoles varies inversely as the fourth power of the distance between them and the combined force of similarly aligned electro-static dipoles over a given surface is squared. The result is that the dipole-dipole force, which varies inversely as the fourth power between colinear dipoles, becomes the familiar inverse square force of gravity for extended bodies. The gravitational and inertial response o f matter can be seen to be due to an identical cause.
Sansbury struggled with a cause for the initial and sustained electrical polarisation within celestial bodies. The initial cause is due to the birth o f stars and planets (see later) in powerful plasma discharge events. Once established, gravity itself provides a weak radial atomic polarisation by drawing the heavy nucleus away from the centre of each atom toward the centre of a planetary body. The resulting radially-orientated dipoles form an electret in the non- conducting minerals of the planet. Surface charge on the planet contributes to the strength of the orientated-dipole electret. This global 'electret' may provide the radial electrostatic field required by Sansbury's model. The electrical model may explain the anomalous gravity readings taken down mineshafts, where Newton's constant, G, was measured to be 1.7 - 3.9% lower than in the laboratory [37]. Rather than invent a 'fifth force' or 'modified Newtonian dynamics' (MOND) [38] to complicate things, it seems we simply need to understand the electrical nature of matter and gravity.
There is another important effect of the orientated-dipole model of the interior of a planet to consider. At some depth where pressure ionisation becomes significant and conductivity increases, charge separation will occur as electrons drift up towards the electret inner boundary. Like charges repel and tend to offset the gravitational compression within celestial bodies. Therefore, changing the surface charge on a celestial body may have a significant orbital effect.
Antigravity?
Conducting metals will shield electric fields. However, the lack of movement of electrons in response to gravity explains why we cannot shield against gravity by simply standing on a metal sheet.
If gravity is an electric dipole force between subatomic particles, it is clear that the force 'daisy chains' its way through matter, regardless of whether it is conducting or non- conducting. Sansbury explains:
... electrostatic dipoles within all atomic nuclei are very small but all have a common orientation. Hence their effect on a conductive piece of metal is less to pull the free electrons in the metal to one side toward the center of the earth but to equally attract the similarly oriented electrostatic dipoles inside the nuclei and free electrons of the conductive piece of metal. '[40]
This offers a clue to the reported 'gravity shielding' effects of a spinning, super-conducting disc [41]. Electrons in a superconductor exhibit a 'connectedness', which means that their inertia is increased. Anything that interferes with the ability of the subatomic particles within the spinning disc to align their gravitationally induced dipoles with those of the Earth will exhibit antigravity effects.
Despite a number of experiments demonstrating anti-gravity effects, no-one has been able to convince scientists attached to the theory of general relativity that they have been able to modify gravity. This seems to be a case of turning a blind eye to unwelcome evidence. Support for antigravity implicitly undermines Einstein's theory [42].
'Instantaneous' Gravity
A significant fact, usually overlooked, is that Newton's law of gravity does not involve time. This raises problems for any conventional application of electromagnetic theory to the gravitational force between two bodies in space, since electromagnetic signals are restricted to the speed of light. Gravity must act instantly for the planets to orbit the Sun in a stable fashion. If the Earth were attracted to where the Sun appears in the sky, it would be orbiting a large empty space, because the Sun moves on in the 8.3 minutes it takes for sunlight to reach the Earth. If gravity operated at the speed of light, all planets would experience a torque that would sling them out of the solar system in a few thousand years. Clearly, that doesn't happen. This supports the view that the electric force operates at a near infinite speed on our cosmic scale, as it must inside the electron [43]. It is a significant simplification of all of the tortuous theorising that has gone into the nature of gravity and mass and I believe Einstein's postulates to be wrong [44]. Matter has no effect on empty space. Space is 3- dimensional - something our senses tell us. There is a universal clock, so time travel and variable aging is impossible - something that commonsense has always told us - but most important, the universe is connected and coherent.
If all that, or something like it is true, poking at the quantum behavior of elements in free fall could shed some light. I'd be interested to see if differently charged condensates behaved differently - especially considering that since they're acting as a single particle, that dipole effect might not apply, or not in the same way.
