The evolution of a shock wave generated by explosions of primordial supernovae, creating the large-scale structures of the universe, has been studied by various authors through analytic approximations or numerical hydrodynamic codes. After the first results of the COBE satellite, some authors concluded that the single explosion scenario was incompatible (e.g., see the 1992 work of Levin, Freese, & Spergel) with the upper limit on the Compton y-distortion (y <~ 1.5 x 10-5). In this work, we compare the single-cycle explosion model with a multicycle explosion model for the generation of voids. We show that the multicycle explosion scenario produces large voids with y lower than in the single-cycle explosion scenario. In comparing the two scenarios, we study the cases of initial explosions at redshifts 20 and 40 for initial masses of 1010--1013 M&sun;.
