What would have happened if Peter had not gone to the tomb of Jesus?
In fact, Peter only went to the tomb of Jesus in Luke and John, which are interdependent gospels. In Matthew, Jesus told the women to tell the disciples to go to Galilee, where he would meet them. Peter did not go to the tomb. In the "Long Ending" to Mark, the women told the disciples that Jesus had risen, but they did not believe. None of the disciples went to the tomb.
