Teleportation is a good point. How could we possibly get a spaceship that close to a pulsar? Maybe our spaceship is made out of diamonds to begin with?
Hmm... It would be an ideal place for a planetary computer. You have a diamond, or maybe "metalic carbon" substrate for a planet the size of jupiter.
Then you have a pulsar clock, and powersource.
Perhaps that's really what we are looking at?
