Laniakea and other super clusters are moving towards shapely super cluster . Even the Great Attractor is moving towards it. Isn't it all about the Big Crunch?

    $\begingroup$ No. the classic definition of the big crunch is the big bang in reverse (kinda/sorta), where it's all the stuff coming back together. Many galaxies may collide given enough time, I'm not sure how many. Perhaps some galactic clusters will collide. I can't give you a good answer on how many or how long until it happens, but I wouldn't call it a crunch because galactic collisions will be periodic, one here, one there, hundreds of millions or billions of years apart. $\endgroup$ – userLTK Mar 31 '18 at 20:13
