The astronauts successfully passed through the wormhole. However, their ship's transmission fails to reconnect and nobody knows where the five astronauts are.

The last message sent to the command base here on earth featured four creatures that looked to be made of the universe itself: stars and planets are visible on their "skin" and their bodies were probably once humanoid but now have began to disintegrate. The text of the message merely said "Vacivus has arrived!"

Neither the astronauts nor this "Vacivus" creature were ever seen on any other space mission to where the wormhole was. Although the wormhole allegedly closed up after the ship passed through because of the instability of the rift. Some believe, due to the matching numbers, that the Vacivi are the distorted and corrupted bodies of the astronauts, doomed to live trapped between universes forever.
