Heres what i don't understand, a massive body in space causes the space around it to warp in accordance with its shape, fine i understand that.
What i don't understand is why the massive body would warp the space beyond the close surface of it's body. Which, according to einstein it does and causes other planets near it to follow the path of this warped space.
I tried likening it to a ball placed in a bath, the water (like space) wraps itself around the ball to accommodate its shape. But the water isn't displaced beyond the ball's shape...unless the ball is rotating like a planet, in which case it would create a swirling current around it.
Maybe a bad analogy but...is this what einstein meant? that planets by rotating create ripples and swirls in space-time, and it is these that the other near by planets 'follow' and are carried along by?
Hope someone can help, as this model of gravity has never really made much sense to me...
