Philip,
In saying, "Simplicity has its role but the only hard principles are logical self-consistency and consistency with observation" you certainly stand with me on common ground...
But would you also join me in the school of realism... e.g., that there is an objective reality independent of our observation of same, that a faithful representation of that external reality is presented to the mind by the senses,that what is presented to the mind by the senses has its foundation in reality, so there is nothing in the mind that did not enter through the senses?
Also, in a realistic metaphysics that includes the principles of non-contradiction and causality?
Causality may be a stumbling block, depending on whether 'emergent causality' refers to some causes of natural effects to be simply unknown... until discovered; or whether it refers to non-existent causes of such effects. If your position is the latter, then prediction with scientific laws is impossible.... Used in this sense 'emergent' becomes for science a fatal emergent-cy. Acceptance of the above means we have minimum common ground for discussion.
If the ground rules above are accepted, then consider:
I take GTR to be an extension of SR to include acceleration and gravitation, that reduces to STR in the 'neighborhood' of an observer. According to MTW, this is true in the tangent hyperplane to an observer's world line. IOW, space is locally flat near any observer.
But STR is an inconsistent system whose first axiom of covariant relative motion is experimentally refuted by the tests of Sagnac, Dufour&Prunier, Ruyong Wang et al, and the second axiom is logically disproved by light beams in opposite directions.... c c = c , with corollary 1 1 = 1. As logicians would say, "An inconsistent system is worse than just being wrong".. For by proving anything is true (or false), nothing can be proven true.
GTR is inconsistent .... whether linearized or not, whether energy is conserved or not, is moot.
Are black holes really credible, Phil? What solution to the Einstein field equations supports the existence of black holes in reality? Two issues to bear in mind are the following:
* All alleged BH solutions to the Einstein field equations pertain to a universe that is spatially infinite, is eternal, contains only one mass, is not expanding, and is asymptotically flat.
However, the hot big bang model pertains to a universe that is spatially finite (one case) or spatially infinite (in two different cases), of finite age, contains radiation and many masses (including some BH said to be primordial), is expanding, and is not asymptotically flat. Thus the BH model and BB cosmology contradict one another; they are mutually exclusive.
* There are no known solutions to the Einstein field equations for two or more masses and no existence theorem by which it can even be asserted that his field equations contain latent solutions for two or more masses.
Re: "...but the evidence for black holes is as good as anything we have in cosmology."
Is the evidence as good as the CMB anomalies in the recent Planck temperature survey that challenges the LCDM & Copernican principle with the Axis of Evil, the multiple multipole alignments with the local directions in space, etc?
Re:" the observation that the universe began from a hot dense state."
Not an observation, Phil, but an interpretation of data collected now, not when the universe began.
Re:"The laws of gravity, quantum mechanics and thermodynamics apply everywhere"
... if 'everywhere' means everywhere on Earth... Elsewhere is unknown. One example: The inverse square law of gravity does not seem to apply to galactic rotation predictions...
Re:"...non-locality does not violate the causality principle. More besides I do not agree that causality is an essential feature of predictive science." ......" Most people think that causality is fundamental. In these ways and others not covered in this essay my thinking is radically different from any other physicist."
To me causality is a self-evident principle of reality.... Give us an example of violation of causality, Phil, where a real event can have no cause.
Re:"I hope you will submit an essay that explains what you mean by that [aether] because it is not part of any theory I am familiar with."
The essay is on aether as an information channel, addressing the topic specified, not the nature of aether.
From other responses:
Re:"..but I don't think the answers require any kind of physical process like a soul to explain consciousness."
I'm wondering.... how would consciousness, memory and other activities of the mind be explained in physical and material terms?
All the best,
Robert
