The universe contains more than matter. Did every last photon ever emitted end up in a black hole too? Or is the universe losing energy with every cycle? This is besides the empirical evidence against a cyclical universe. Cosmological expansion is accelerating, rather than slowing down, as you would expect if gravity were to slow everything down enough to eventually contract.
