According to the canon movie Star Trek Generations, the Nexus is an extra-dimensional realm in which time and space have no meaning. The main antagonist of the film, Tolian Soran, wants to enter the Nexus so he could be reunited with his deceased family. His plan
succeeds initially, but using the Nexus, Captain Picard stops him, leading to Soran's death.
However, if time is irrelevant in the Nexus, and Soran
succeeded in one version of the plan,
does that mean that he is technically in the Nexus with a version of his deceased family?
