[DBZ] So I take the dragon balls from earth to some far away planet I make my wish, then where do they go back to earth?

Great question! A few things to consider is the creator of the dragon balls.

It would depend on where the creator of the dragon balls is located. If not the creator, then whomever is spiritually tied to them.

Consider the time during the Frieza saga, when they called upon Porunga (the Eternal Dragon of the planet Namek), and after Guru died, he was later revived by the Shenron (the Eternal Dragon of Earth). The final wish was made to Porunga (Guru bestowed him with the power to grant three wishes, and two of which had been used to revive Piccolo and bring him to Namek).

Well, the third wish was used to transport everyone except for Frieza and Goku to Earth, where the titans Goku and Frieza were left to clash on the dying Planet Namek. Well, when the wish was granted, the dragon balls followed Guru to Earth. They go where their creator is

Given that the dragon balls in the DB universe follow a few guidelines such as not having the ability to grant wishes to exceed the power of their creator, limited by number of wishes, and maybe some other intricate details, and the only known creators of dragon balls have been Namekians, it is safe to assert that the dragon balls of Earth would also go where their creator is.
