Scientific paper

Attention is given to the process whereby large-scale structure would form in a neutrino-dominated universe. Thermal velocities that had persisted in the neutrino gas since the big bang should have significantly limited the maximum neutrino density in the first 'pancake' structure to develop. It is shown that along the caustics, where the density should formally become infinite for a cold medium, the thermal-velocity dispersion should hold the density to no more than 10-20 times its mean value. It is pointed out that in a collisionless gas, such as the neutrino gas, one-dimensional contraction will cause the random 'thermal' velocities of particles to take on a decidedly antistropic distribution.
