hi and yes i have read all other threads and news about the discovery of ring of dark matter. i was just wondering would the ring of dark matter would consist of the same composition (materials, matter etc)????? because i was just wondering...if the collision of 2 galaxies clusters and cause a ripple of dark matter showing the ring ..wouldn't that ring is make up of the same stuff as dark matter.. like ripple of water in a pond...that ripple ring is still water right?? any idea?? and sorry, for jibburishing.. i just type what comes out of my head. because i am very lost and confuse LOL.
