	The Universal Laws of Gravity and Repulsion
		The flow rate of gravity particles in close proximity and on the surface of a cosmic object is determined by the size and average radii of the mass, the effects of any nearby mass and the density in which the mass resides in.
		Gravity deflects incoming photon particles due to pressure from a crowded field of gravity particles, the higher the concentration of gravity particles the greater the deflection of photon particles.
		Gravity particles, now subjected compression from new arrivals are pushed further into the center of the core, where their original static charge is overwhelmed by the opposite polarity charge at the center that attracted them.

	Quantum gravity: progress from an unexpected direction
		Quantum gravity, the as yet unconsummated marriage between quantum physics and Einstein's general relativity, is widely (though perhaps not universally) regarded as the single most pressing problem facing theoretical physics at the turn of the millennium.
		In contrast, the general relativity community views the geometrical nature of Einstein's gravity as sacrosanct, and would by and large be quite willing to do a little drastic surgery to the foundations of quantum physics if they felt it unavoidable [2].
		On the other hand, ``Lorentzian lattice quantum gravity'' has irritated both brane theorists and general relativists (and more than a few lattice physicists as well): It does not have, and does not seem to require, the complicated superstructure of supersymmetry and all the other technical machinery of brane theory/ string theory.

		Gravity is widely used with magnetics in geological mapping and exploration, and has prime application in base metal, gold and diamond exploration.
		Induced Polarization (IP) is an electromagnetic method that uses electrodes with time-varying currents and voltages to map the variation of electrical chargeability (dielectric constant) in the Earth at low frequencies.
		Induced Polarization is observed when a steady current through two electrodes in the Earth is shut off: the voltage does not return to zero instantaneously, but rather decays slowly, indicating that charge has been stored in the rocks.

	Aristotelian theory of gravity - Wikipedia, the free encyclopedia
		The Aristotelian theory of gravity was a flawed theory that stated all bodies move towards their natural place.
		Isaac Newton was the first to mathematically codify the newer theory of gravity according to which any mass, not only the Earth, is attracted to other masses according to a function of their mass and the inverse square of their distance.
		In 1915, Newton's theory was overthrown by Albert Einstein, who developed a whole new picture of the nature of gravity, in the framework of his general theory of relativity.

	MESO's CAFE --- Gravity Waves
		Gravity waves are one of many methods the atmosphere uses to transfer momentum (as well as temperature and moisture), and in the process, attempt to establish an energy equilibrium.
		Some of the fundamental physical characteristics of gravity waves are not well-understood or well-documented, but in general, here are some basic guidelines: they typically have a 1-15 millibar amplitude (vertical displacement), a 50-500 kilometer wavelength, and a period of 1-4 hours.
		Gravity wave-induced condensation ripples were traveling SSE across Texas, and by the early afternoon, they encountered a substantial dryline.

	PowerPedia:Anti-gravity - PESWiki (Site not responding. Last check: 2007-10-15)
		In quantum gravity theories, either the graviton is the postulated carrier of the gravitational force, or time-space itself is envisioned as discrete in nature, or both.
		Gravity was no longer a force at all, but simply the consequence of the local slope of the universe in a direction the human eye cannot see: a fourth spatial dimension.
		In common usage "gravity" and "gravitation" are either used interchangeably, or the distinction is sometimes made that "gravity" is specifically the attractive force of the earth, while "gravitation" is the general property of mutual attraction between bodies of matter.

	Induced gravity - Wikipedia, the free encyclopedia
		Induced gravity (or Emergent gravity) is an idea in quantum gravity that space-time background emerges as a mean field approximation of underlying microscopic degrees of freedom, similar to the fluid mechanics approximation of BEC.
		Developments in AdS/CFT correspondence after 1997 suggest that the microphysical degrees of freedom in induced gravity might be radically different.
		The bulk space-time arises asan emergent phenomenon of the quantum degrees of freedom that live in the boundary of the space-time.

	Gravity and antigravity (1)
		Her equation for ‘circular’ force (including gravity) is F = aA, where a is the acceleration and A is the area of a circle with a radius equal to the mean distance of the orbiting body from the central body.
		Spolter believes that her gravity equation solves the mystery of Kepler’s third law of planetary motion: this law states that the ratio of the cube of the mean distance (r) of each planet from the sun to the square of its period of revolution (T) is always the same number (r³/T² = constant).
		Various conventional explanations have been put forward to explain gravity anomalies during eclipses, such as instrument errors, gravity effects of denser air due to cooling of the upper atmosphere, seismic disturbances caused by sightseers moving into and out of a place where an eclipse is visible, and tilting of the ground due to cooling.

	Earthquake-Induced Base Sliding of Concrete Gravity Dams (Site not responding. Last check: 2007-10-15)
		Analytical procedures are developed considering hydrodynamic effects to determine the response history of earthquake-induced sliding of a gravity dam monolith supported without bond on a horizontal, planar surface of rock.
		The results presented indicate that the permanent sliding displacements of dams induced by ground motions with peak acceleration of 0.5g may range from a few inches to a couple of feet.
		Also examined in this work is the possibility of estimating the sliding displacement of a flexible dam due to ground acceleration by analyzing the sliding response of a rigid dam due to an average (over height) acceleration computed from linear analysis of the flexible dam without sliding at the base.

	Studies of gravity wave–induced fluctuations of the sodium layer using linear and nonlinear models
		Simulations indicate that a stable gravity wave induces large perturbations to the atomic sodium distribution at the bottomside of the sodium layer and that the perturbations are in phase with those of temperature.
		The response of the sodium layer to gravity waves is largest around 86 km, in the bottomside of the sodium layer, where the vertical gradients of sodium are larger.
		For a large amplitude gravity wave the nonlinear simulation of the sodium layer evolution is reasonable, while the linear simulation gives an unphysical solution at the bottom side of the sodium layer.

	Researchers to Use Satellite Duo to Measure Earth's Gravity Field
		With gravity, that omnipresent force that keeps humans firmly on the Earth and prevents planets from careening out of their orbits, it's the little things that researchers are interested in.
		Such studies led to the discovery of lower than normal gravity off India's shores, apparently due to the structure of mantle material beneath the Earth’s crust.
		Researchers with the European Space Agency hope to launch the Gravity Field and Steady State Ocean Circulation Explorer, a one-year mission to map the planet’s gravitational field and physical shape, by 2005.

		The induced gravity restrains the Sun's plasma from further outward expansion, and it is the struggle between the inhibiting induced gravity and the repulsive magnetic properties of the plasma which cause the solar shell to radiate.
		As with gravity, the attraction to the eye falls off with the square of the distance from its center.
		If suns can induce gravity - make more gravity than the corresponding quantity of mass allows - then they will have sought a way to do so, for it is the nature of all life-forms to seek an excellence of efficiency.

		The gravity wave drag parameterization used at NMC is a fairly crude approximation of gravity waves forced by flow over topography.
		Otherwise the stress is not absorbed with height until either 1) a critical level is encountered at which point the momentum flux vanishes or 2) the gravity waves break and generate turbulence from shear or convective instability or 3) from wave saturation.
		The gravity wave drag-induced velocity tendency change is computed as the vertical divergence of the momentum flux as described above in eqns.

	Sensing probe for gravity induced flow liquid level regulator - Patent 4108201
		Such liquid level regulators are essentially barometric systems in which the flow of liquid from the reservoir to the sump is controlled by the pressure differential existing between the atmospheric or air pressure exerted on the liquid in the sump and the air pressure present above the oil level in the reservoir.
		When the liquid level in the sump is at the desired level the liquid covers and seals that end of the sensing conduit within the sump and prevents the flow of air to the reservoir.
		A sensing probe for a gravity induced flow fluid level regulator has a shield which enables the probe to sense an average liquid level at the probe tip.

	Key to Test #2 (7/3/00)
		This observation indicates that the time during which gravity fixes the polarity of rhizoid emergence and growth must occur during the first 24 h after light initiates germination.
		Ans.: The genes are nph1, which encodes the photoreceptor protein for phototropism, and cry1, which encodes the photoreceptor for the blue light induced inhibition of hypocotyl elongation.
		If the return of shaded light (namely, FR light) when the wind subsided could not reverse this process, the seed would be irreversibly induced to germinate even though it would still be at a competitive disadvantage.

	Paradoxes Resolved, Origins Illuminated - Antigravity Research
		Another is to develop a physics that describes inertia, gravity, or the properties of spacetime as a function of electromagnetics that leads to using electromagnetic technology for inducing propulsive forces.
		So, if Mel is correct that spin might be reversed to redirect gravity, then what we may be seeing is the normal patterns of dominance of forward time quarks change under a redirection of the geometry of the electromagnetic fields creating a greater frequency stream of modulation of the reverse time antiquarks within the proton.
		In conclusion, the explanation by Mel Winfield that the proton reverse spin causes repulsion within gravity field may be accurate in regards to the antiquark becoming the dominant force in maintaining a new field geometry that is out of phase and in dissonance to the relativity of earth’s electromagnetic forces.

	Storm-induced sediment gravity flows at the head of the Eel submarine canyon, northern California margin
		BBL measurements revealed that during intensifications of the wave orbital velocity, sediment transport at the head of the canyon occurred as sediment gravity flows directed down-canyon.
		Rather, liquefaction of sediment deposited at the head of the canyon (induced by wave-load excess pore water pressures during storms) combined with elevated slopes around the canyon head appear to be the mechanisms initiating sediment transport.
		Results from this study reveal that storm-induced sediment gravity flows occur periodically in the Eel Canyon head, and suggest that this kind of sediment transport process can occur in other submarine canyons more frequently than previously expected.

	Space Habitat Design Considerations Related to Different Gravity Environment (Site not responding. Last check: 2007-10-15)
		Reduced and artificially induced gravity levels relative to the Earth’s have major influences upon human operations, health and safety that must be carefully considered throughout all habitat planning and design processes.
		These considerations include influences upon astronaut/cosmonaut mobility, task performance, bone and muscle deterioration, fluid loss, psychological and spatial adaptation, and in the case of artificially induced gravity, impacts of Coriolis forces and cross-coupled accelerations.
		In designing for different gravity environments, architects must address both physical and psychological adaptation and operational problems for humans who exist beyond their natural environment.

	CFT and black hole entropy in induced gravity
		We present a derivation of the entropy of fl holes in induced gravity models based on conformal properties of induced gravity constituents near the horizon.
		We demonstrate that in the vicinity of the horizon constituents of the 2D induced gravities are described by conformal field theories (CFT) with specific central charges depending on spin and non-minimal couplings and with specific correlation lengths depending on the masses of fields and on the momentum p.
		The sum of partial entropies correctly reproduces the Bekenstein-Hawking entropy of the 4D induced gravity theory.
