Gravity

From Academic Kids


The popular model of general relativity, as causing a flat surface like a rubber sheet to curve into a manifold is unhelpful to further progress in unifying quantum space with gravitation, since physical space fills volume, not surface area. This ‘obvious’ fact is obfuscated by jargon in physics! Instead of 11 dimensional and ‘multiple universe’ speculation (http://www.math.columbia.edu/~woit/blog/), consider what physics can do with experimentally-proved properties of space: real space is in physics as electric impedance (mc = 377 ohms for a vacuum, allowing radio transmission), electric permittivity, magnetic permeability (m), it forms a vacuum foam and causes particle-wave duality (Dirac ‘space sea’).


Fact 1: the big bang is receding galaxies with observable speed increasing linearly with time past, v/t = constant acceleration

Fact 2: by Newton’s 2nd empirical law, F = ma, the mass of the galaxies times acceleration is outward force of the big bang

Fact 3: by Newton’s 3rd empirical law, forces have equal and opposite reaction: so equal inward force is proved, thus gravity


This inward force is carried by the fabric of space around accelerating matter, so the inward pressure (force/area) gives rise to the inverse-square law of gravity (see illustrations), causing gravitation where shielded by mass (http://cdsweb.cern.ch/search.py?recid=706468&ln=en).

‘In many interesting situations… the source of the gravitational field can be taken to be a perfect fluid…. A fluid is a continuum that ‘flows’... A perfect fluid is defined as one in which all antislipping forces are zero, and the only force between neighboring fluid elements is pressure.’ – Bernard Schutz, General Relativity, Cambridge University Press, 1986, pp. 89-90.

The correct force of gravity is proved below: F = mMG/r2, where G = (3/4) H2/( p r local e3 ) = 0.0119H2/r local = 6.7 x 10-11 Nm2kg-2. This is not speculative: all 3 facts above are hard experimental results. Electromagnetism and nuclear forces are well-known energy exchange processes, but gravity is not.
