Gravitational waves can penetrate regions of space that electromagnetic waves cannot. They allow the observation of the merger of black holes and possibly other exotic objects in the distant Universe.
Nothing ever seems to stop gravitational waves, with the only alterations we see coming from the effects of distorted spacetime due to the presence of masses and the expanding Universe. But on the other side of the coin, we have black holes, which have an event horizon: a region from within which nothing can escape
