Can someone with some astronomy knowledge explain why the center of the images has a bunch of concentric-ish smudges? What does it mean?

    So, are the smudges' light coming from behind the objects in the center?

      Yes, they are being warped and magnified by the central cluster of galaxies.

  The smudges are proof that Einstein was correct
