if there is repulsion in micromasses that the wouldnt the same rules would also apply for macromasses=note didnt Einsteins postulate of relativity indicate that all rules of physics apply to all frames of refernces?

More confusing nonsense?

Gravity has never been observed to repel. Although anti gravitons are theoretically possible (according to some models), these fundametal messenger particles have never been observed.
The reason Earth stays away from the Sun, rather than falling into it, is because Earth would really rather travel in a straight line. According to one of Newton's laws, all mass bodies, like Earth, want to travel in a straight line and when something like the Sun tugs at them with gravity to make them turn, centrifugal force results. Centrifugal force is a reaction force that pulls the Earth away from the Sun. "Centrifugal" literally means "flee the center." The Sun in this case is the center...the center around which the Earth revolves.

Gravity alweays Pull.
The earth has 2 velocties. One normal to sun and another tangential . SUn has control obver the normal velocity. But this tangential velocity which is constant pushes away from the sun at the lowest point and saves the earth not falling in to the sun.
Read about orbital mechanics for more about orbits.

Well i am not sure if earth tries to move towards sun as i am of the opinion that the earth revolves around the sun. And any body that revolves round an object tends to move outwards.

What made you think the sun is repulsing the Earth? Is the Earth moving away from the sun?

it never repels it. it acts on it and earth due to inertial continues to move closing its orbit . if it was completely circular it would act like the CENTRIPETAL force. since it is an ellipse it is quite close to the circular movement. speed is very important to this phenomeneon.
if it is too large to might go off the orbit and continue to travel with out control. if it is too smal it will collide to the center such as an satellite that orbits the earth

The gravitational pull of the sun holds all the planets in orbit.

The sun is playing hard to get, it's way too hot for the planet earth and it knows it. Earth is just way out of it's league!!!(Thee-hee-he)
