Re: The Causal Identity of Gravity - 07-17-2007, 02:56 AM

---Quote (Originally by RascalPuff)---

1.. Gravity on or near a major coordinate system is the omnidirectionally
accelerating expansion of the coordinate system itself; constituting the 4-D
space time continuum of matter-energy.

2.. This generates a repelling force, causing objects to be pinned to the
earth's surface, and the apparent 'descent' of objects in free fall...

Rascal ......

Point 1 seems to re-state Einsteins Principle of Equivalence. I have never heard
anyone on this forum disagree with this principle.

Point 1 does restate Einstein's Principle of Equivalence.

*From the Wiki* ... The equivalence principle proper was introduced by Albert
Einstein in 1907, when he observed that the acceleration of bodies towards the
center of the Earth at a rate of 1g (g = 9.81 m/s2 being the acceleration of
gravity at the Earth's surface) is equivalent to the acceleration of an
inertially moving body that would be observed on a rocket in free space being
accelerated at a rate of 1g. Einstein stated it thus:

"we [...] assume the complete physical equivalence of a gravitational field
and a corresponding acceleration of the reference system." (Einstein 1907)

What I am not quite clear on is your Point 2. Why do you claim that acceleration
*generates* a repelling force. Do you disagree with inertial mass? Can you
extroplate this part ?

Are you not familiar with the example of Einstein's elevator thought problem? I ask, because you seem to be familiar with the principle of equivalence at the same time that you question it's results.... When you accelerate in your car and are thrown back in the seat, you are experiencing the results of a repelling force. Your body's negative inertia is resisting acceleration against it. I don't understand your quandary at these facts...

Regarding the neutron star proximity you speak of, since we aren't near any neutron stars it isn't presently tenable to speculate on how that would effect Point 2.
