All

George;
You have merely stated that which I have previously said.
I re-iterate: Newton explained the laws and showed the correct maths of the laws but he did not understand the mechanics.
It is the 'mechanics' which at our level of understanding of the laws, becomes the (only) vital issue.

Guillaume, I agree that the mechanics (as you say) or the root cause (as I say) of gravity is not understood. Apart from that, the Newtonian laws (corrected for Relativity) explain very well all gravitation phenomena. So we know how it works, but not why.

George Metaxas:

Newton gave us, correctly the 'laws' or "effects" (as you say) of gravity, he did not know the mechanics of gravity or if he did, he never explained the mechanics..

Please give your understanding of the precise and detailed mechanics with which the Moon has a pulling effect on the oceans. Include both oceans and solid matter. Show please the mechanics and not Newtons maths.

Gravity’s effects are well understood since Newton era, although the root cause of gravity is still escaping. Gravity is indeed a pulling only force (until proved otherwise), but electromagnetic forces can be either pulling or pushing. As about the oceans, moon pulls more on the water facing it, but pulls less on the water on the other side of the Earth, that’s why there are two high tides simultaneusly on opposite sides of Earth. Also, when moon pulls on the water, water pulls on the moon with just the same force (in magnitute).

The Science establishment has absolutely no idea, exactly, what gravity is.
Until 'they' know they will probe around in the dark looking for anti-gravity forever.

If the Moons gravity pulls on the oceans of the Earth creating the tides then I ask what, exactly reaches out and 'grabs' the ocean and pulls it towards the Moon.
I know of nothing in the particle physics world that can do this, pushing yes, pulling no.

CERN is looking for the particle that will prove the big bang as I understand its purpose, well let me tell you CERN you are wasting public money by keeping a lot of people in a fat salary by playing nursery games.
