            Abstract

            In this article, the strong equivalence principle is analyzed by the gravitational mechanism of etheric pressure, and the conclusion is drawn that an object at rest in a uniform gravitational field of a certain strength is equivalent to moving in a straight line in a uniform etheric space with a certain speed (not a certain acceleration). According to this gravitational mechanism, gravitational field is a scalar (energy) field, and gravity is caused by the asymmetric density distribution of space energy, resulting in the asymmetric etheric pressure on the object at rest in space. The experimental fact of equivalence between gravity fields and velocity (rather than acceleration) in terms of time dilation has proven the equivalence between uniform gravity fields and inertial systems with uniform motion. It further deduces that gravity fields are equivalent to velocity in terms of the increase in the inertial mass effect of objects, and gravity fields are equivalent to velocity in terms of the contraction effect of the electron orbit radius of atoms. The Ether (energy) field with a gradient of field strength generated by a fluid whose flow velocity decreases perpendicular to its motion is equivalent to the gravitational field with a gradient of field strength. Using these modified and extended equivalence principles, the author explains Newton's bucket experiment, the Casimir effect, and explains what reference system the flow rate of fluid in Bernoulli equation is relative to, and why the higher the flow rate is relative to the reference system, the lower the pressure.

            Review of the article "The Modification and Extension of the Equivalence Principle" submitted to the ScienceOpen Preprints for open peer review

            1. The authors presented a well-organized paper that was easy to read and follow.

            2. In this paper, the authors have analyzed the strong equivalence principle by the gravitational mechanism of etheric pressure.

            3. The authors have shown that an object at rest in a uniform gravitational field of a specific strength is equivalent to moving in a straight line in a uniform etheric space with a certain speed.

            4. The authors have also shown that the gravitational force received by an object at rest in a gravitational field with a field gradient is equivalent to the inertial force the object gets in a linear acceleration motion in ether.

            5. The authors have concluded that the ether field with field gradient produced by a fluid whose velocity decreases in the direction perpendicular to the motion is equivalent to the gravitational field with field gradient.

            6. There is a clear methodology. There is an extensive explanation of the method and a discussion of the results.

             

            However, I suggest the authors consider the following issues.

            1. The abstract is relatively long. I suggest the authors present shorter abstract of the revised copy of the manuscript.

            2. The language of the article has to be slightly revised. The attached file includes many suggestions and comments on the first two pages of the manuscript.

            3. The list of references is relatively short. I suggest the authors enhance the introduction of the manuscript to cover more related work in the literature.
