Abstract

Ten years ago this week, the two authors had an email conversation about black holes, ER bridges, and EPR entanglement. This brief note contains a verbatim translation of these emails. While the ideas expressed in this email dialogue linking [1] and [2] are more mainstream now than they were back then, there are still many unresolved puzzles, some of which are discussed in this old correspondence.
