  First-order phase transitions can leave relic pockets of false vacua and
their particles, that manifest as macroscopic Dark Matter. We compute one
predictive model: a gauge theory with a dark quark relic heavier than the
confinement scale. During the first-order phase transition to confinement, dark
quarks remain in the false vacuum and get compressed, forming Fermi balls that
can undergo gravitational collapse to stable dark dwarfs (bound states
analogous to white dwarfs) near the Chandrasekhar limit, or to primordial black
holes.
