Vainshtein radius

From Wikipedia, the free encyclopedia

Inside the Vainshtein radius[1]

with Planck length and Planck mass

the gravitational field around a body of mass is the same in a theory where the graviton mass is zero and where it's very small because the helicity 0 degree of freedom becomes effective on distance scales .[2]
