Abstract: The symmetry-breaking phase transition that is believed to have occurred 10 s after the dawn of time at the Big Bang would appear to lie forever beyond the reach of experiment. This is unfortunate, because topological defects in space-time created during the transition may perhaps have provided the primordial density inhomogeneities that later gave rise to galaxy formation. Arguably, however, the physics of this remote event can be investigated in the laboratory  through studies of mathematically analogous but more accessible phase transitions. One such experiment  involved the fast adiabatic passage of a small volume of liquid He through the lambda (superfluid) transition. The results, and new experiments currently being planned, will be discussed.
