Question

why does repulsion does not take place in gravitational force

Answer 1

Answer:

The “gravitational force” is part of a theory of gravity that explains the phenomenon in terms of forces (so you can use Newton's Laws of motion to make predictions). The force is attractive because the phenomenon is one of “accelerating together”. There is no way a repulsive force describes that

Answer 2

Explanation:

If Sun burst up suddenly then it travels in the form of Gravitational waves which is also have speed of the light. If there be Gravitational Force then there be repulsive force. But if Gravitational Force is not right, Gravitational pull is right then there be not need of repulsive force.
