Explosions in the early universe will send shock waves through the intergalactic medium, which sweep up matter and compress it into thin, cold shells. If a shell becomes gravitationally unstable it may fragment into bound objects which themselves explode. This sequence, proposed by Ostriker and Cowie (1981) for amplifying galaxy formation, may in principle repeat itself many times, resulting in a cosmological detonation wave. Two models are presented here for cosmological detonation waves. The first is a perfect-gas model, where a shocked gas element instantaneously releases heat and thereafter evolves adiabatically. The second model includes cooling and fragmentation processes, and assumes that explosions are discrete. In both cases isolated explosions can, for a wide range of initial energy and epoch, process mass up to cluster (100 trillion to 1 quadrillion solar mass) and perhaps supercluster (10 quadrillion solar mass) scales. Fragmentation of the swept-up shells leads to preferred mass scales for globular clusters (1 million solar masses) and galaxies (1 trillion solar masses).
