Could ``ROC'' Support My Hypothesis of The Dark Matter Ring

A new observation of ``odd radio circles" has a structure which likes my hypothesis of the ring structure of the dark matter. he dark matter is a spacetime (backgroundwave) which has close-ring structureand center structure, a density of the spacetime (spacetime/massenergy), and a negative gravit. And the spacetime field can cause the Hubble's Red Shift. If the``ROCs'' are some high density structures of the spacetime (field) which can Redshift the high frequency radiations to low frequency radio waves, ``ROCs''can be observed by the radio telescope.
