Essentially gravity is not a force in the traditional sense; what really happens is that space is bent by mass, and then objects travel through this bent space. The most popular analogy is of placing a heavy ball like a bowling ball on a rubber sheet so that it bends, and then pushing a marble across the rubber sheet so that it orbits the bowling ball. In the traditional Euclidian model space would just be some kind uniform straight grid which the ball would intersect without resistance and then it would pull the marble by a 'force'.

There is no known 'reason' for this, it is just how nature works; in a non-Euclidian fashion.

All the questions I can see are repetitions of things I've already explained a couple of times or just nonsenses (like 'I was just taking a guess at what you could possibly be talking about since you are not telling me' - when I'd already explicitly told you that it was general relativity, not special relativity. You clearly just didn't know the difference.).
