As far as i understand the gravity is described as being a space "curvature" around any "mass". So should be a kind of "stress" in the space (just like the rubber sheet analogy) which is higher near the mass and decreases with the distance. In case of Earth's gravity, I imagine that an object had different relative dimensions at different altitudes. What i don't understand is why objects are falling toward Earth and why they just don't change dimensions (elongate). A droplet of liquid in free falling will fall apart after reaching a certain speed (and other causes). Shouldn't the droplet just elongate in the view of a stationary observer basically with no change in shape and structure from the point of reference of the falling droplet? With other words...Isn't the presence of gravitational acceleration violating the "space curvature" theory?..I hope its not so confusing as i am...! Another stuff that i don't get is the two synchronized clocks situation, one on a spaceship speeding with relativistic speeds, the other one on Earth. On the speeding ship the time will slow down and the story say, that an observer on Earth will be older than the astronaut when he will return with the ship... I just have the feeling that the relative time difference is happening only when the ship is accelerating and will reverse itself when the ship will decelerate, so, should not be any time difference on the two clocks at the end.....Am i in clouds with relativity?
