Does the 'Gravitational Field' really exist?
Does the 'Gravitational Field' really exist?
In the following discussion I am going to lay out the case that what has been called ‘the fourth force field of the universe' which is ‘the gravitational field' is a theoretical scientific fiction, which is to say that the ‘gravitational field' does not exist. Anyone who is familiar with problems in science over the course of the 20th century would know that the gravitational force field is sitting in isolation upon some shelf awaiting a solution which would somehow make this field consistent with Quantum Mechanics (the mathematics produces a kind of infinite loop which cannot be resolved using such techniques as ‘renormalization'). If the gravitational field is a scientific fiction then it follows from this that the endless fruitless search for a theory of ‘Quantum Gravity' is just a wild goose chase. http://www.awitness.org/unified/page...y_fiction.html A summary of the Unified Field Theory http://www.awitness.org/unified/pages/new_physics.html |

A "Unified Field Theory" would be nice, because that might better explain how a planet or a moon can become associated with another body other than whatever was originally created at the exact same time and place. Removing the "matter based field" of gravity would greatly help, even though a force of gravity might still coexist in much the same as secondary/recoil photons exist. ~ BG |

There is a litmus test for any viable theory of the *cause* of
gravity. Actually the test consists of two parts: 1.) Supernovae and hypernovae. Does the theory explain (not describe) the literal mechanism powering the stellar collapse that drives the fusion that rebounds as a SN (or HN) blast? (We're not talking about describing fusion processes which are well understood.) When the core fusion cascade abruptly shuts off at iron, what *very real*, ever- present force from without literally initiates and POWERS the collapse? 2.) Quasars. Does the theory explain (not just describe) the *very real* and continuous force that powers and sustains the far more energetic process of a quasar? Before the discovery of super/hypernovae and quasars, gravity could be described variously by its perceived *effects* like "curvature of space", "fictitious force", 'transfer particles' (gravitons) that mysteriously reach up and pull stuff down, etc. But now with the advent of SN/HN and quasars, those *descriptions of effects* can no longer suffice. What is the very real, causal mechanism behind those effects? oc |

A molecule of water or any other known element doesn't require or otherwise depend upon the weak force of gravity. However, like secondary/recoil photons, the extremely weak force of gravity should still have an affect, especially when trillions upon trillions of such molecules gather because of the strong forces that'll exist within any given volume. ~ BG |

First of all, I'm no physicist. Just thought I should make that clear. =) I think "the gravity field" exists, at least, in the sense that it is a useful and accurate tool for describing a system. It's 'reality' should matter little to us beyond this. Ultimately, though, I think Einstein's characterization that gravity is equivalent to a warping of space-time is most accurate. At any rate, both analogies agree with experiment, so the answer is essentially 'yes', it does in fact exist. |

Correct, the weak force of gravity could be nearly meaningless, though obviously a secondary/recoil reaction kind of force none the less. Once a given item such as Earth is comprised of enough bazillions upon bazillions of those atoms is where that otherwise extremely weak force takes on meaning. However, if Earth was a ball of hydrogen gas, or worse yet a thin shell of a hollow planet that's mostly displaced by an interior of hot hydrogen and helium gas is where the notions of gravity gets more than a little thin, and even reversed within that hollow sphere. Gravity Force Inside a Spherical Shell (is always zero) http://hyperphysics.phy-astr.gsu.edu...ell2.html#wtls The zero delta-V and extreme vacuum (thus minimal local gravity) of Selene L1 (earth-moon L1) is even more special. Too bad we still do not have any platform of science instruments within that zero delta-V location. ~ BG |

Try this physics-101 analogy out for size: When any volume of water is exposed to the lunar environment, and especially on the daytime heated portion that’s so physically dark, regardless of whatever local or self imposed gravity of Newtonian binding force that may or may not exist between those molecules of h2o, whereas these individual molecules will quickly vaporize and become purely individual atoms of hydrogen and oxygen (no chance of their forming into raw ice or remaining as liquid), shortly before those too seem to vanish by further breaking down into subatomic particles that are rather easily associated with all those other solar wind and cosmic particles that usually far exceed the lunar escape velocity, and thereby summarily blown/extracted away by the persistent flux of our solar and cosmic wind, all because of the insufficient local and molecular gravity, as well as there’s obviously too little surrounding pressure at 3e-15 bar. Within our Selene/moon L1 is where the extreme vacuum of that nifty Zero Delta-V location is likely worth 3e-21 bar or less (a millionth the pressure of what the lunar surface has to offer), that’s always assisted by the continuous 2e20 N/sec of tidal force. Obviously there’s always the passing solar and cosmic flux that’s continually populating this nearby Zero Delta-V location. If the Newtonian force from Earth didn’t exist, that same distance from the moon (roughly 34r) would only realize a pressure of 2.6e-18 bar. Also interesting to note, is if the moon had the same mass as Earth it would only amount to a surface atmospheric pressure of 1.81e-14 bar. Too bad that after a half century and counting, we still have nothing of any science platform interactively situated within that absolutely nifty and easily established location.
