"First explored by Robert R. Caldwell, Marc Kamionkowski, and Nevin
Weinberg"....
No, it wasn't first explored by these gentlemen. See for example

http://arxiv.org/abs/hep-th/0112066

Which, in fact, they cite. Note too [from this paper] that phantom
cosmologies *do not* have to be singular.</description>

		<description>1. Feynman diagrams, the physics behind the maths of quantum field theory, show that forces arise from the exchange of gauge bosons (coming from distances at light speed, hence coming from times in the past).

2. The big bang mass has an increasing speed, in our observable spacetime, from 0 toward speed of light c with times past of 0 toward 15 billion years (or distances of 0 to 15 billion light-years), giving outward force by Newton's 2nd empirically based law: F = ma = m.dv/dt = m(c - 0) / (age of universe) = mcH, where H is Hubble's constant (based on v = HR, where R is distance).

3. Newton's 3rd empirically based law suggests equal inward implosion force, carried by gauge bosons, which shielded by mass, proves gravity and electromagnetism to within 1.65% (proof below). This mechanism also predicts particle masses and other observables, and eliminates most of the unobserved 'dark matter' speculation and the need for a cosmological constant / dark energy (the latest data suggest that the 'cosmological constant' and dark energy epicycle would need to vary with time!

These are all existing accepted facts; the Feynman diagrams are widely accepted, as is the spacetime, the big bang, Newton's laws of motion. The result, that apples fall at the measured acceleration, is apparently 'only a personal pet theory that should be suppressed from arXiv.org and ignored'. Drs Lee Smolin and Peter Woit could sit under an apple tree to verify that existing 'string theory' gravity is 'speculative gibberish': it is an effort to destroy science using untestable hocus pocus 'string theory'!



Update: Lee Smolin has now kindly acknowledged the possibility of using this type of argument (that quantum field theory gauge boson exchange process predicts magnetic moments and Lamb shift, so an attempt to unify the spacetime fabric with Feynman path integrals is an empirically defendable physical reality, unlike 'string theory' speculation). This applies for some kind of spin foam vacuum in loop quantum gravity, as mentioned on Peter Woit's blog. Smolin is committed to the very difficult mathematical approach, but was decent enough say:


Nigel Says: January 14th, 2006 at 2:18 pm

Some kind of loop quantum gravity is going to be the right theory, since it is a spin foam vacuum. People at present are obsessed with the particles that string theory deals with, to the exclusion of the force mediating vacuum. Once prejudices are overcome, proper funding of LQG should produce results.

Lee Smolin Says: January 14th, 2006 at 4:41 pm

... Thanks also to Nigel for those supporting comments. Of course more support will lead to more results, but I would stress that I don't care nearly as much that LQG gets more support as that young people are rewarded for taking the risk to develop new ideas and proposals. To go from a situation where a young person's career was tied to string theory to one in which it was tied to LQG would not be good enough. Instead, what is needed overall is that support for young scientists is not tied to their loyalty to particular research programs set out by we older people decades ago, but rather is on the basis only of the quality of their own ideas and work as well as their intellectual independence. If young people were in a situation where they knew they were to be supported based on their ability to invent and develop new ideas, and were discounted for working on older ideas, then they would themselves choose the most promising ideas and directions. I suspect that science has slowed down these last three decades partly as a result of a reduced level of intellectual and creative independence avaialble to young people.

Thanks,

Subject: Your_manuscript LZ8276 Cook
{MECHANISM OF GRAVITY}
Physical Review Letters does not, in general, publish papers on alternatives to currently accepted theories.... Yours sincerely, Stanley G. Brown, Editor, Physical Review Letters

'... the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them. Thus it happens that whenever those who are hostile have the opportunity to attack they do it like partisans, whilst the others defend lukewarmly...' - http://www.constitution.org/mac/prince06.htm

'(1). The idea is nonsense. (2). Somebody thought of it before you did. (3). We believed it all the time.' - Professor R.A. Lyttleton's summary of inexcusable censorship (quoted by Sir Fred Hoyle in 'Home is Where the Wind Blows' Oxford University Press, 1997, p154).</description>
