Is there any evidence that the great attractor isn't just gravitationally lensed gravity? It seems odd that it would be directly on the other side of the black hole at the center of our galaxy and not just be a distortion of what we see while every time we find a way to look a little further in that direction we find something apparently bigger.

  • $\begingroup$ Equating gravitional waves and gravity does not work. You are looking for an attractor, not for infinitesimal fluctuations of the metric. $\endgroup$ – Stéphane Rollandin Mar 1 '18 at 17:30
  • $\begingroup$ @StéphaneRollandin something made of gravity is gravity. $\endgroup$ – CoryG Mar 1 '18 at 17:54
  • $\begingroup$ This depends on the context. In the context of your question, no, obviously. Gravitational waves are not in any way responsible for the motion of galaxies, they can't even move an atom in a noticeable way, so there is no way they can behave as the great attractor, lensed or not. Doing physics is not playing with words. Without an understanding of orders of magnitudes and domains of validity, you only get sloppy thinking. $\endgroup$ – Stéphane Rollandin Mar 1 '18 at 19:02
