The macroscopic gauge theory of gravity is applied to the so-called cosmological problem of uniform-density gravitational collapse. In this theory, gravity itself is considered as a basic manifestation of the hadronic and leptonic world, a current with a hadronic part and a leptonic part is introduced for the coupling, and lepton pair creation strongly affects the lepton current and always decelerates the contraction of a hot collapsing system provided the hadronic photon entropy is sufficiently high. The elements necessary to describe the collapse of a uniform density distribution are summarized, and general properties of the gauge-type collapse equations are examined. It is shown that in the gauge theory of collapse, physical processes can actually terminate the gravitational collapse of a uniform matter distribution. One such process is analyzed: electron-positron and muon pair creation in a hot collapse at temperatures of 5 billion and 800 billion K. The collapse equations are then applied to the case of hot collapse of a nonrelativistic hadronic plasma, where lepton dominance in the structure function may occur.
