- 4,500,001,994: According to Senator Richard Matheson, the Sun will exhaust its fuel and swell to engulf the Earth. Unless intercepted, the Voyager spacecraft, which launched from the Kennedy Space Flight Center in 1977, will still be in space.
- In the episode "Little Green Men", Senator Matheson claims this will happen "four and a half billion years from now". As the episode is set in 1994, it can be assumed that he is referring to the year 4,500,001,994.
