Question about Basics of Gravity

Gravity doesn’t work that way, so I don’t see how that aids in conceptual understanding. Your drawing says a gap is no gravitational attraction. You also say gravitation toward the center but that’s not what the lines say.. Gravitational field lines are supposed to tell you the direction of the field at that point.

The actual field was solved and is figure 2 in this paper

Thanks for the link.

A visual gravity diagram I developed, see attached. Just the gravity aspect. 

Let me know if my understanding of the gravity layman definition is correct or also wrong.

In my opinion this thread has wandered way off topic in the last couple of years and for several of its 5 pages.

 

I have been looking back over it and you don't seem to have progressed very far and I have some serious and fundamental comments to make about your diagram especially in the light of the one you posted recently on the previous page.

 

After all this thread is called Basics of Gravity.

So I would like you to think about several points before I post my comments.

 

First and foremost you need to realise that the are two separate aspects of 'gravity'.

1. The are the objects which cause gravity or the gravitational  field or the gravitational potential.
    
2. There are the effects of gravity on susceptible objects.

Each aspect has its own terminology and, which are often confused between on aspect and the other.

 

As to the causes the effects can be divided into two parts.

1. The nature and distribution of the gravitational field outside the surface of a body.
    
2. The nature and distribution of the gravitational field intside the surface of a body.

Related to these categorisations are the terms Centre of Mass and Centre of Gravity which often coincide, but not always.

Ok, thanks.

I'll look into and think about it a bit more in order to learn a bit if it make sense.

Great then I suggest you re-read page 1 as it contains much useful information.

I'm sorry if you felt then that I was pushing alternative models or explanations. I did say that there are several models and suggested you stick to the basic one first.

After all you introduced quantum gravity. GUT and TOE etc and I have trying to play these down.

An update (see attached image). I'm in some degrees of aware that it might be approximately close to right, wrong, or both. I think this is for time being, at least for me.

Thanks to you and other posters for participation in this thread so far. Seems more further physics and mathematics would be a step in understanding gravity and etc more better.
