A New Theory of Gravity by David Harvey

[bigview]

The universe is rapidly expanding, and as we know: for every action, there is an equal and opposite reaction. Gravity is a universal field effect generated as an equal & opposite reaction to the force of universal expansion. By analogy, an elevator car traveling upwards produces downwards G-force, pressing an occupant into the elevator floor. A jet accelerating forwards on a runway produces backwards G-force, which causes a passenger to be pushed into the seatback. So, upward thrust produces downward G-force, while forward thrust produces backwards G-force. An outwardly expanding universe produces inward G-force at every point within itself. This universal force pushes inwards upon all planetary bodies, giving rise to their gravity. Those bodies do not generate an attraction to one another at all. Rather, the curvature of space around planetary bodies is actually interference, or impingement, of a universal field.

 

In the previously mentioned examples of the elevator and the jet, those are material objects in motion. However, in the case of the expanding universe it is space itself that is expanding, not a material object. Most matter is atomically porous, because atoms are comprised primarily of empty space with less than 1% of their overall mass consisting of subatomic particles. Therefore, the universal G-force is able to flow through the empty space within atomic structures, and is obstructed only by the presence of the subatomic particles themselves. This largely porous quality of matter, including large planetary bodies, is responsible for the illusion that gravity is a relatively weak force.

 

Take for instance the case of neutron stars, which are not atomically porous. There is no empty subatomic space within them in-between the neutrons that form their mass. Therefore, these objects are more efficient at interfering with the all-pervasive pressure of universal G-force, resulting in gravitational force roughly 200 billion times stronger than that of the earth. From this example, we can see that universal Gravity is not weak at all when it is actually “blocked” effectively. Gravity has a reputation of being a weak force simply because atomically porous matter is inefficient at blocking it.

 

Viewing gravity in this manner, as a universal field effect rather than a local attraction between material bodies, explains away the dichotomy between the amount of known matter present in the universe that is insufficient to produce gravity by attraction. Therefore, there is no need for the hypothesis of dark matter to account for material attraction, because matter does not generate material attraction. Rather, in the case of gravity, matter serves as an obstruction in the flow of universal compression.

Great blurb, now can you give us some details of this theory and maybe some suggestions on how it could in principal be discriminated from general relativity.

The analogies presented in post #1 are logically inconsistent.

 

For example if I stand on a thick steel plate on the elevator floor, both the plate and I are pressed to the floor, the addition of the plate does not provide any shielding or interference effect.

 

Suppose further that gravity were a 'universal field'. Then in order to "interfere with this field" as stated, a massive object would perforce have to produce a counterfield of its own, contrary to the stated premise.

 

Actually I prefer the term interact, rather than interfere, which has some specifically different connotations.

 

Finally in suggesting that a massive object can interfere with the field to the side of the body and at a distance from it is contrary to the suggested notion that massive objects just block it by being in the way.

Note that we know light is deflected in passing massive bodies to the side.

Gravity cannot be an equal but opposite reaction to the expansion of the universe because the two forces would be equal. The equal but opposite reaction to the expansion of the universe has something to do with dark energy, something not well known about.

The bold part

Gravity is an effect generated as an equal & opposite reaction

Is something that crossed my mind too.

I am not sure if it is related to the expansion of the Universe. One should go step by step before jumping from a speculation to another speculation.

Stating that gravity is a reaction to something is enough, IMHO.

Where is David?

Hello-o

Who is David?

 

[EDIT]

Sorry, somehow missed the name in the headline, but still is bigview David Harvey or someone else?

Let's assume bigview and David Harvey are the same person, since the name is mentioned only once, in the title, with no citation link to a paper.
