I'm sure you already know that a paragraph I could write here could never do it justice. But, as a coincidence, there is a favorite magazine that I subscribe to, and it's from the UK. It's called: "How It Works". I particularly enjoying more about Biology, which is not my major. But, relative to your inquiry about gravity, the newest issue that I just received has a front cover "What If There Was No Gravity?" I have not read it thoroughly yet, [we've just begun our new semester, leaving all a lot of "paperwork", all due tonight], but when I saw the formula: F = G(m1xm2)/r^2, which I teach in my second semester course, it really caught my attention. I also noticed a number of other facts, necessary to develop that formula. By the way, the "F" on the left side of the equal sign is the ""force of gravitational attraction"". Must of us know that as our ""weight"" seen when you get on a scale. But, actually, it's the force of attraction, and the m1 and m2 would be: our body mass & the mass of the earth. Just so I can peak your interest even more, there is a force of attraction between ANY two objects of mass. So, when you sit at your desk, there is a gravitational attraction between *the mass of your body, and *the mass of your desk. Pick ANY two objects of mass, around you per chance, and consider that must be a gravitational force between any two of them.
Oh, by the way, the article I mentioned is "Issue 179" and sells for 5.50 British pounds. I'm hoping you might have an extensive "book store and newspaper store" near you. It's worth every penny, or should I say pence?

You, like so meany others, speak in terms of manifestations of gravity and not its root origination. Even the equation you refer to, and the examples you give, defines how it works, not why it works.
Thank you sir for your time.
