However, I'm performing a time travel experiment by orbiting close to a black hole for a month. I leave orbit 500 years later, thanks to relativistic effects, after all writing sites have been restored, so I don't get bored.
The next user tries the same experiment, but accidentally crosses the event horizon, so they fall into the black hole.
The flame is extinguised because I am on the moon.
the next person is under the influence of trance music and cannot controll themselves.
