Abstract. The mantle is the intersection of all ground models of the universe. By a result of Usuba, the mantle is a ground in the presence of an extendible cardinal. In his recent work, Goldberg argues that this large cardinal hypothesis cannot be weakened. I shall discuss these results in the context of the axiom of resurrection, outlining a plan for my research project. This is a project supervised by W. Hugh Woodin.
