3x23 - Dragon Ball Z: Dragon Box

Using the Dragon Balls, it is possible to bring Goku and Kuririn back to life in the same place where they died. However, now that Planet Namek no longer exists, the place where they died is in the vacuum of space. The hopes of bringing them back to life are dashed in an instant. But then, Vegeta proposes that they can summon their souls to Earth and then bring them back to life. Just how will that idea turn out?
