Universe, I'm Back!

Three factors were of paramount importance for a space jump.

The most important factor was naturally the coordinates of the destination, which was a series of information sets made of hundreds of parameters.

Not only had they elaborate on the relative position of the destination in the universe, they would also have to illustrate the speed and trajectory of the star and even the galaxy nearby, which made them extremely sophisticated.

Even if only one of the thousands of parameters was missing or wrong, those who were teleported could be sent somewhere not even close to the original destination.

The second factor was the star beacon.

The star beacons were equivalent to lighthouses in the sea of stars. To sail on a vast ocean, it would be useless to only know the location of the 'port'. In the stormy, dark, or foggy days, only with the continuous guidance of one or more lighthouses could a ship expect to arrive at the destination successfully.
