DESCRIPTION:Inflation solved the cosmic homogeneity problem. But does Infl
 ation itself require a homogenous patch to begin? We investigate this prob
 lem in full 3+1 numerical relativity. We show that while large field infla
 tion is very robust to inhomogeneities\, small field inflation fails in th
 e presence of sub-dominant gradients. We also show that\, for large field 
 inflation\, attempts to stop inflation by forming a black hole spacetime w
 ill fail as long as the initial hyperslice is roughly flat.
