    Gravity
AI Thread Summary
The discussion centers on the interpretation of gravity, challenging the traditional view of it as a force. Participants argue that gravity should be seen as a stress within the fabric of space-time, rather than a simple force with magnitude and direction. They highlight that general relativity (GR) describes gravity as a property of space-time, emphasizing the importance of reference frames and the distortion of space-time caused by mass. The conversation also touches on the need for a four-dimensional perspective and the role of the Stress-Energy Tensor in understanding gravity. Overall, the thread explores the complexities of gravity beyond classical Newtonian physics.

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.

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe.
