Discussion Overview

The discussion revolves around the conceptual understanding of gravity, particularly in the context of Einstein's theory of general relativity (GR). Participants explore whether gravity should be considered a force or a property of space-time, and how this relates to classical and modern physics perspectives.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that gravity should not be classified as a force, proposing that it acts more like a stress with magnitude, direction, and volume.
  • Another participant agrees that gravity is not a force in the Newtonian sense but emphasizes that general relativity treats gravity as a property of space-time, incorporating time into the discussion.
  • A different viewpoint describes space as a fabric and time as a pattern that gets distorted by mass, suggesting that gravity is the stress in the space-time grid caused by this distortion.
  • One participant questions whether their thinking is too classical, indicating a concern about aligning their understanding with modern interpretations of gravity.
  • Another participant acknowledges the classical nature of general relativity but points out the necessity of considering four dimensions and the role of the Stress-Energy Tensor in describing gravity.

Areas of Agreement / Disagreement

Participants express differing views on the nature of gravity, with some agreeing that it is not a force while others emphasize the importance of time and space-time properties in understanding gravity. The discussion remains unresolved, with multiple competing views present.

Contextual Notes

There are references to classical and modern physics concepts, including the Stress-Energy Tensor and the metric signature used in general relativity. The discussion includes assumptions about the nature of gravity and the interpretation of space-time that may not be universally accepted.

Feel free to entertain the following idea. Please feel free to poke holes in my thought
process, but keep in mind there are other ways to tell whether a balloon is filled with water
or air other than popping it. I’ve taken a few college level engineering physics classes so feel
free to post your replies as technical as you want.

Gravity isn’t a force. Forces have two dimensions, magnitude and direction, while gravity

appears to act more like a stress, which has magnitude and direction along with an area but

in this case it’s a volume of space.

Can this be interpreted as Einstein’s Gravity?

If you mean general relativity then no, why has the time not been taken into consideration ? GR essentially proposes gravity to be a property of space-time.Gravity is not a force,you're right that was the idea of Newtonian physics.GR is all about reference frames... one of the postulates is that: If a reference frame is uniformly accelerated relative to a Galilean one,then the body would be considered at rest due to uniform gravitational field.

The way I see it is that space is the fabric and time is the pattern that forms a uniform grid when mass isn’t present. When mass is present it distorts the uniform pattern, kind of like if a vat of molten metal solidified at the center of the vat first creating tension on its surroundings.

Gravity isn’t the force two objects exert on each other; it’s the stress in the space/time grid created by the tension of the distortion. Space/time gravitates matter in a reverse osmosis pattern, moving from volumes of less density to volumes of higher density, in order to keep as much equilibrium (i.e uniformity of the space/time grid) as possible. Almost like space/time is trying to isolate the disturbance created by masses.

thanks for your last response

GR is a classical theorem (i.e. not quantum). You are kind of right but you need 4 dimensions and a (- +++) metric signature. The Stress-Energy Tensor which describes the source of gravity is a rank 2 tensor (4 X 4 in 4D) the T00 element is the energy density, and the diagonals are momentum flow, which is a pressure.
