Inside the Vainshtein radius

r V = l P ( m P 3 M m G 4 ) 1 5 with Planck length l P and Planck mass m P

the gravitational field around a body of mass M is the same in a theory where the graviton mass m G is zero and where it's very small because the helicity 0 degree of freedom becomes effective on distance scales r ≫ r V .
