Do gravitational waves exsist?

Yes.
The question was settled once and for all last week, when scientists at the Advanced Laser Interferometer Gravitational-Wave Observatory (Advanced LIGO) reported that they had detected gravitational waves emanating from the violent merger of two black holes more than one billion light-years away. Picking up the signal — a tiny flurry of contractions and expansions in space-time called a “chirp” — required extraordinary technical finesse. But it also took 100 years for scientists to determine what, exactly, Einstein’s theory predicts: not only that gravitational waves exist, but how they look after crossing the cosmos from a coalescing pair of black holes — inescapably steep sinkholes in space-time whose existence Einstein found even harder to swallow.

Yes, they do. I remember reading about this from another source. I'm sure from one of your posts.
In my opinion, they may be more complex than implied in the piece. Like ripples in water, waves from multiple sources could encounter one another, cancelling some out, but others could create an interference pattern, and still others could intensify a wave. I believe they call those rogue waves.
I'm betting that one day they'll find that to be true.
