Large nucleation distances from impurities in the cosmological quark - hadron transition

, in a first order cosmological quark-hadron phase transition. For homogeneous nucleation we find that self-consistent inclusion of curvature energy reduces

d_{nuc}

to

\lesssim 2

cm. However, impurities can lead to heterogeneous nucleation with

d_{nuc}

of several meters, a value high enough to change the outcome of Big Bang nucleosynthesis.
