Gravitational motion transitions into universal expansion over distance

In summary, the paper discusses how the recessional motion experienced by masses over large distances is similar to the attractive gravitational motion experienced by masses over short distances. It is based on the similarities of the two motions that a transition from gravitational attraction to universal expansion is observed.

I’d like to know if anyone has heard of anything along the lines in this article (abstract and link are below) before - that gravitational atractive motion sort of fades into universal expansive motion as distance increases…and how that relates to Chernin's concept of a “zero gravity shell”.

Thanks

Abstract
A comparison of the attractive motion experienced by masses due to gravitational interaction over relatively short distances with the recessional motion of masses at relatively large distances (that adhere to the velocity increases described by Hubble's v = Hr relation) is presented to demonstrate the similarities between the two motions. Based on the similarities of the two motions, and the observation that gravitational acceleration decreases as distance increases while recessional acceleration decreases as distance decreases the distance at which the two accelerations are equal in magnitude but in opposite directions resulting in zero net acceleration is calculated and compared to similar results provided by Chernin et al. [1]. The summation of the attractive gravitational acceleration and the recessional acceleration is presented and plotted depicting a smooth, continuous transition from gravitational attraction to universal expansion. The underlying cause of these accelerations is not addressed.

That paper is nonsense. It starts assuming that Hubble's constant is constant over time which is wrong.

Note: This paper is deposited on the vixra.org site, which allows anyone to deposit papers, partly in protest at what is seen as censorship by arxiv.org. I've nothing against this, and am thinking of launching a similar site myself, but I think using the domain name rxiv.org is downright deceptive.

Yes – the Humble’s parameter H changes with time. But treating H as a function of time would only make the some of the math a bit more cumbersome – dv/dt would be equal to H*dr/dt + r*dH/dt instead of just being eqaul to H*dr/dt - the similarities between gravitational motion and universal expansion would remain the same in that v=rH(t) would still result in an inertial accelerative expansion of some magnitude. Or would they? Maybe H(t) could vary just enough to keep v(t) constant. Any evidence of that? Or to the contrary?
Accurate point about vixra.

No other comments? Any interest in the independent derivation of Chernin's "zero gravity surface"?
Thanks

I am familiar with the concept that gravitational motion transitions into universal expansion over distance. This idea has been explored and studied by many researchers in the field of cosmology. In fact, the abstract and link you have provided seem to be discussing a specific comparison between gravitational attraction and recessional motion, and how they both decrease with distance. This is a well-known phenomenon and has been observed through various experiments and observations.

In terms of Chernin's concept of a "zero gravity shell," this refers to the distance at which the attractive gravitational force and the expansive recessional force are equal in magnitude, resulting in a net zero acceleration. This concept has been proposed and studied by many scientists, and the abstract you have provided seems to be discussing a similar idea.

Overall, the idea that gravitational motion transitions into universal expansion over distance is a well-established concept in cosmology. However, the underlying cause of these accelerations is still a topic of ongoing research and discussion. I would recommend further exploring the research and studies on this topic to gain a deeper understanding of the mechanisms behind these motions.
 

1. What is gravitational motion?

Gravitational motion refers to the movement of objects due to the force of gravity. This force is caused by the mass of the objects and the distance between them.

2. How does gravitational motion transition into universal expansion over distance?

As objects move further apart, the force of gravity between them decreases. This allows for other forces, such as dark energy, to become dominant and cause the expansion of the universe.

3. What evidence supports the transition from gravitational motion to universal expansion?

The observation of redshift in the light from distant galaxies is a key piece of evidence for universal expansion. This redshift is caused by the stretching of light waves as they travel through expanding space.

4. Is the transition from gravitational motion to universal expansion a continuous process?

Yes, the transition from gravitational motion to universal expansion is a continuous process. As the universe continues to expand, the force of gravity becomes less and less significant in comparison to other forces.

5. How does this transition impact the movement of objects in the universe?

The expansion of the universe causes objects to move further apart from each other. This can impact the motion of galaxies, clusters of galaxies, and other structures in the universe.
