A question about gravity
OK, here we go...
I understand how the Higgs particle is supposed to give objects their mass. Massive matter interacts with the Higgs field and that's what "slows it down", "gives it mass"... Like an object passing through a dense liquid - it feels "heavier", "more difficult to pass through, (than in a vacuum, for example)"...
Also, I can understand that massive objects warp spacetime around themselves. I can imagine curved space around a star and the effect it has on planets, light, etc... They follow the shortest way around the star.
Using a 2-D analogy... When you put a billiard-ball (planet Earth) on an elastic surface (spacetime), the surface becomes curved and if you push a pebble (the Moon) in the right direction at the right speed, it will circle around the billiard-ball (well, before friction slows it down and it falls into the hole created by the billiard-ball).
But the 2-D analogy is flawed, because here Earth's gravity is what pulls the ball and pebble down...
So I understand why the moon follows the path it follows, the spacetime is curved... But what I don't understand is, what PULLS the moon to the earth.
In our analogy, if you were to stop the pebble in orbit around the billiard-ball, it would not fall onto the billiard ball, were it not for the Earth's gravity to pull it down.
So once again, to sum it up... I understand how an objects is supposed to get its mass, I understand that the massive objects warp spacetime around themselves, I understand why smaller objects orbit in circles (ellipses) around massive objects... But I still don't get how gravity "PUSHES/PULLS" an object onto another massive object. And since gravity and acceleraction are equivalent according to Einstein, what causes a massive object to accelerate towards another massive object.
Am I even making sense with this question?
