Science World ISSN 1367-6172

In February 1997, I launched the monthly and later weekly journal Science World, ISSN 1367-6172. The image above is from the spoof news site http://www.theonion.com/content/node/28269 which says:

'Stephen Jay Gould Speaks Out Against Science Paparazzi' August 22, 2001 Issue 37•29:

'... According to Gould, paparazzi often use illegal means to secure photos for such notoriously disreputable tabloids as Science World Weekly and Starz, which bills itself as "your most trusted source for astronomy celebrity news."

'Exacerbating the situation is the fact that paparazzi photos often accompany stories that are inaccurate or outright libelous.

'"The tabloids make little effort to ground their stories in reality," Gould said. "A recent Science World Weekly story claimed I was starting a project in organic stereochemistry and conformational analysis, which is preposterous.

'Another tabloid recently ran a contest offering the winner a romantic evening carbon-dating fossils with me in my lab. I never agreed to any such contest." '

This is totally false, it was never published in Science World Weekly!

Improved introductory gravity material










Empirical evidence and proofs of heuristic mechanisms for a simple mechanism of continuum field theory (general relativity and Maxwell’s equations) and quantum field theory, including quantum mechanics

Objective: Using empirical facts, to prove mechanisms that make other predictions, allowing independent verification

General relativity and elementary particles
Quantum mechanics and electromagnetism
Quantum field theory and forces
Fact based predictions versus observations

By Hubble’s empirically defensible and scientifically accurate law, big bang has speed from 0 to c with spacetime [‘The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.’ – Hermann Minkowski, 1908] of 0 toward 15 billion years, giving outward force of

F = ma = m.dv/dt = m(c - 0) / (age of universe) = mc/t ~ mcH = 7 x 1043 Newtons.

Newton’s 3rd law tells us there is an equal inward force, which according to the possibilities implied by the Standard Model, must be carried by gauge bosons, which predicts gravity constant G to within 1.65 %. Proof.

A simplified version of the proof so that everyone with just basic maths and physics can understand it easily; for two separate rigorous and full accurate treatments see Proof.

The radiation hits a mass almost equally from all directions, coming from other masses in the universe. The radiation is reflected back the way it came if there is symmetry that prevents the mass from being moved. The result is then a mere compression of the mass by the amount mathematically predicted by general relativity, i.e., the radial contraction is by the small distance MG/(3c2) = 1.5 mm for the contraction of the spacetime fabric by the mass in the Earth.

If you are near a mass, it creates an asymmetry in the radiation exchange, because the radiation normally received from the distant masses in the universe is red-shifted by high speed recession, but the nearby mass is not receding significantly. By Newton’s 2nd law the outward force of a nearby mass which is not receding in spacetime from you is F = ma = mv/t = mv/(x/c) = mcv/x = 0. Hence by Newton’s 3rd law, the inward force of gauge bosons coming towards you from that mass is also zero; there is no action and so there is no reaction. As a result, the local mass shields you, creating an asymmetry. So you get pushed towards the shield. This is why apples fall.

The universe empirically looks similar in all directions around us: hence the net unshielded gravity force equal to the total inward force, F = ma ~ mcH, multiplied by the proportion of the shielded area of a spherical surface around the observer (see diagram). The surface area of the sphere with radius R (the average distance of the receding matter that is contributing to the inward gauge boson force) is 4 pi R2. The ‘clever’ mathematical bit is that the shielding area of a local mass is projected on to this area by very simple geometry: the local mass of say the planet Earth, the centre of which is distance r from you, casts a ‘shadow’ (on the distance surface 4 pi R2) of its shielding area multiplied by the simple ratio (R/r)2. This ratio is very big. Because R is a fixed distance as far as we are concerned for calculating the fall of an apple or the ‘attraction’ of a man to the Earth, the only significant variable is the 1/r2 factor, which we all know is the Newtonian inverse square law of gravity. Varies as the inverse-square law. For two separate rigorous and full accurate treatments see Proof.
