Background information

• Going by Data's statement that the The energy ribbon from Star Trek Generations passes through the Milky Way Galaxy every 39.1 years, it can be expected to return in 2410, 2449, and 2488.

Apocrypha

• In the game Star Trek Online, Humans reach the Delta Quadrant in the year 2410, along with the Romulan Republic and the Klingon Empire, through the use of Dyson spheres and Iconian gateways. This contradicts the Q's prediction of Humans reaching the Delta Quadrant in 2472. This year also sees the Iconians return from exile in the Andromeda Galaxy and engage in a massive invasion of the Milky Way, forcing all the major powers of the galaxy to join together to fight them.
