what makes the bodies to exert gravitational force?

Question

we all know that two bodies will exert gravitational force on them.but what makes them to exert such a force

Answer 1

Mass....bodies with greater mass exhert greater gravitational force.
Mass constantly attact one another.

Answer 2

We now have a very convenient law, which tells us exactly how much force a body exerts on another due to the masses of the two interacting bodies, but we still don't know the answer to the eternal question "What inside or around a body makes it exert a force on another body?"

We have theories like fields, and potentials, but these are more mathematical tools than physical explanations.

So to answer your question, we don't know.

Answer 3

I think Einstein said that the greater the mass, the greater the distortion of the space-time continuum. Like a bowling ball on a matress, is how I've heard it. Of course, I'll believe it when I see it...

Answer 4

I think
kram
is right there is an unknown property of masses that allows it to attract any other body with mass ;
it is yet to be discovered
