  While quantum gravity is not solved yet, a screening mass for the graviton
remains theoretically possible. If such a mass would screen gravity at
distances of the order of the cluster galaxy radius, it could account for the
universe expansion. The modified Newtonian dynamics model also could be related
to a screening graviton mass at inter-galactic scales. Moreover, massive spin-2
theories constitute a very active theoretical topic. We briefly show how the
very recent LIGO gravitational wave observation GW150914, emitted by a binary
black hole merger distant $\sim 1.3 \times 10^9$ ly from the Earth, tightens
the phenomenological bound on a massive graviton or on the screening of
gravity.
