Quantum gravity physics based on facts, giving checkable predictions

Time past T in Hubble's law v = HR = H(cT) is related to time t since the big bang by t + T = 1/H. => v= HcT = Hc[(1/H)-t] = c - (Hct) => a = dv/dt = d[c-(Hct)]/dt = -Hc, the outward acceleration. Force, F = ma. Newton's 3rd law gives a reaction force, inward directed gravitons. Since non-receding nearby masses don't cause this reaction force, they shield graviton exchange with more distant masses in that direction; an asymmetry which produces gravity.

Google falls for the wrongful bigotry of owner of Crank Dot Net...

http://www.crank.net/gravity.html:

Cause of gravity and mechanisms of forces 2005 Feb 12 ... gravitation . Big Bang ...
"As the big bang mass goes outward, the fabric of space must flow around each fundamental particle, filling vacated volume. The inward moving fabric exerts space pressure, increasing as it acts inward upon smaller areas, thereby causing the correct force of gravity where it is shielded by mass."

The extract above omits the maths and physics on the page linked to (http://members.lycos.co.uk/nigelbryancook/).

Let's first ignore the fact that the quotation is taken out of its mathematically and physically defended context, and just look at what they see as being crackpot.

They think the Higgs field of the Standard Model, the 'spacetime fabric' which fills three dimensional volume, is crackpot. Wrong. It is the basis for mass in the Standard Model. They are too chicken to be specific as to what they think crackpot, so let's assume that everything they quote is what they see as being crackpot: they think the Higgs field and thus the Standard Model crackpot, as well as the perfect fluid analogy to general relativity (Feynman-Lesage gravity, see my page), and the force of gravity itself... Now remind me why I'm crackpot?

Is the joke also on Benjamin Franklin, for drawing the arrow from + towards - ?

So the conventional current goes the other way to true current?

By the way, the first open publication of nuclear EMP was by the Russian, Dr Kompaneets, in 1959. It was in a peer-reviewed Soviet physics journal.

Dr Richard Garwin in 1965 published the fact Kompaneets had the sign of the EMP wrong!

All Soviet publications of the period show the EMP electric field from a surface or air burst starting with a positive electrif field pulse.

In fact, because of Franklin, the upward compton current pulse starts the EMP electric field with a negative pulse. Apparently the Soviets never measured the EMP waveform because they couldn't work out how to photograph a microsecond transient on an oscilloscope screen. The Americans simply fixed up polaroid cameras facing the screen, and added a circuit to make the beam stay off screen until the firing signal went to the bomb. It was turned off a second after burst. Nice EMP curves resulted. The Soviets by contrast "measured" the EMP using spark-gaps and fuses and by looking at their burned out electronics.

Perhaps you should ridicule the Russian peer-review system, PhD system, and the American discoverer Franklin, first.

So Ivor is not alone in worrying about signs. For my part, I think the big bang means outward motion, which leads to the physical mechanism. The maths follows the experimental facts, so I'm not too worried about being sloppy in early formulations...

Best wishes,
Nigel

In general relativity, the square of the differential element of time is used (details here Feynman gravity home page).

When you square any real number, you get a positive one. Hence -2 squared is +4, as is +2 squared.

Therefore, all your and Ivor's drievl about the sign of time is a waste fo time and is wrong.

Mathematical symbols in this blog: your computer’s browser needs access to standard character symbol sets to display Greek symbols for mathematical physics. If you don’t have the symbol character sets installed, the density symbol "r" (Rho) will appear as "r" and the "p" (Pi) symbol will as "p", causing confusion with the use of "r" for radius and "p" for momentum in formulae. This problem exists with Mozilla Firefox 3, but not with Microsoft Explorer which displays Greek symbols.

‘Dr Edward Teller remarked recently that the origin of the earth was somewhat like the explosion of the atomic bomb...’ – Dr Harold C. Urey, The Planets: Their Origin and Development, Yale University Press, New Haven, 1952, p. ix.

‘But compared with a supernova a hydrogen bomb is the merest trifle. For a supernova is equal in violence to about a million million million million hydrogen bombs all going off at the same time.’ – Sir Fred Hoyle (1915-2001), The Nature of the Universe, Pelican Books, London, 1963, p. 75.

‘In fact, physicists find plenty of interesting and novel physics in the environment of a nuclear explosion. Some of the physical phenomena are valuable objects of research, and promise to provide further understanding of nature.’ – Dr Harold L. Brode, The RAND Corporation, ‘Review of Nuclear Weapons Effects,’ Annual Review of Nuclear Science, Volume 18, 1968, pp. 153-202.

‘It seems that similarities do exist between the processes of formation of single particles from nuclear explosions and formation of the solar system from the debris of a [7*10²⁶ megatons of TNT equivalent, type Ia] supernova explosion. We may be able to learn much more about the origin of the earth, by further investigating the process of radioactive fallout from the nuclear weapons tests.’ – Dr P. K. Kuroda, University of Arkansas, ‘Radioactive Fallout in Astronomical Settings: Plutonium-244 in the Early Environment of the Solar System,’ Radionuclides in the Environment (Dr E. C. Freiling, Symposium Chairman), Advances in Chemistry Series No. 93, American Chemical Society, Washington, D.C., 1970, pp. 83-96.

How would a 10⁵⁵ megaton hydrogen bomb explosion differ from the big bang? Ignorant answers biased in favour of curved spacetime (ignoring quantum gravity!) abound, such as claims that explosions can’t take place in ‘outer space’ (disagreeing with the facts from nuclear space bursts by Russia and America in 1962, not to mention natural supernova explosions in space!) and that explosions produce sound waves in air by definition! There are indeed major differences in the nuclear reactions between the big bang and a nuclear bomb. But it is helpful to notice the solid physical fact that implosion systems suggest the mechanism of gravitation: in implosion, TNT is well-known to produce an inward force on a bomb core, but Newton's 3rd law says there is an equal and opposite reaction force outward. In fact, you can’t have a radially outward force without an inward reaction force! It’s the rocket principle. The rocket accelerates (with force F = ma) forward by virtue of the recoil from accelerating the exhaust gas (with force F = -ma) in the opposite direction! Nothing massive accelerates without an equal and opposite reaction force. Applying this fact to the cosmological acceleration of matter in the universe which was predicted accurately in 1996 and later observationally discovered in 1999 (by Perlmutter, et al.), we find an outward force F = ma and inward reaction force by the 3rd law. The inward force allows quantitative predictions, and is mediated by gravitons, predicting gravitation in a checkable way (unlike string theory, which is just a landscape of 10⁵⁰⁰ different perturbative theories and so can’t make any falsifiable predictions about gravity). So it seems as if nuclear explosions do indeed provide helpful analogies to natural features of the world, and the mainstream lambda-CDM model of cosmology - with its force-fitted unobserved ad hoc speculative ‘dark energy’ - ignores and sweeps under the rug major quantum gravity effects which increase the physical understanding of particle physics, particularly force unification and the relation of gravitation to the existing electroweak [SU(2) x U(1)] section of the Standard Model of fundamental forces.

Richard Lieu, Physics Department, University of Alabama, ‘Lambda-CDM cosmology: how much suppression of credible evidence, and does the model really lead its competitors, using all evidence?’, http://arxiv.org/abs/0705.2462.

A type Ia supernova explosion, always yielding 7*10²⁶ megatons of TNT equivalent, results from the critical mass effect of the collapse of a white dwarf as soon as its mass exceeds 1.4 solar masses due to matter falling in from a companion star. The degenerate electron gas in the white dwarf is then no longer able to support the pressure from the weight of gas, which collapses, releasing enough energy as heat and pressure to cause the fusion of carbon and oxygen into heavy elements, creating massive amounts of radioactive nickel-56. Type IA supernovae occur roughly once every 400 years in the Milky Way galaxy. When the solar system formed 4,540 million years ago, a supernova occurred 100 light years away from the solar system, and the heavy radioactive debris expanded at 1,000 miles/second. On 4 July 1054, Chinese astronomers observed in the sky (without optical instruments) the bright supernova in the constellation Taurus which today is still visible as the Crab Nebula through telescopes. The Crab Nebula debris has a diameter now of 7 light years and is still expanding at 800 miles/second. The supernova shock wave triggers star formation; bright stars are observed in the Orion Halo, the 300 light year diameter remains of a supernova. Essentially all of the heavy elements including iron, silicon and calcium in the Earth are products from a supernova explosion.
