# Are gravitational waves effected by the curvature of space time (gravitational lensing)?

I have a basic question I can't seem to find anything on (I keep hearing about how gravitational waves and gravitational lensing were both predicted by Einstein).

We all know about the gravitational lensing effect as it relates to light. Would a gravitational wave also be subject to having its path "bent" around massive objects/following the curvature of space-time, or would it be able to pass "straight" through? (Or do we know?)

• This paper analyses strong gravitational lensing effects on gravitational waves: arxiv.org/abs/1309.5731 – user106422 Feb 13 '16 at 2:35
• Roughly speaking, a gravitational wave carries energy and momentum and gravitation acts on everything that has energy and momentum, so a gravitational wave should be deflected similarly to light. – Robin Ekman Feb 14 '16 at 2:02
