when i view images of the cmbr, i see possible evidence of a cyclical expansion. the temperature gradiant appears to swirl in a fairly consistant manner and direction.  now, consider this cyclical expansion an oscillation of an expanding universe, a universe that is expanding and then rescinding, as described by the cyclic model. if the universe experiences periods of oscillation, then the oscillations must be examined for causation, with gravity being undoubtedly a component. so if, gravity plays a part in the contractions of the universe. how does this comport with its infinite or finite reach?

in the cyclic model each oscillation is followed by an expansion. the size of the expansions and contractions remain uniformed to the previous expansion. so that when a contraction takes place an increase in matter ensues, followed by an increase in gravity. when an expansion cycle takes place, the universe expands proportionally in response to the increase in gravity via a repeller/attractor model for dark matter. in this case dark matter constites the hidden atractor that forments the expansion cycle. 

if the above is represenative, gravity is reduced to a secondary status during the expansion phase, which in essence limits it's effect. can anything that is limited, truly be infinite? logic dictates, it cannot.
