'Dragon Ball Super' Explains the Real Rules Behind Time Travel

The Dragon Ball series is no stranger to outlandish science fiction concepts and ideas, and this definitely comes to a head in the Future Trunks arc in Dragon Ball Super. The English language broadcast of the series is midway through the arc, and it's clarified how time travel works within the series.

Naturally, only some characters are allowed to time travel freely lets they tear apart the fabrics of reality.

When Whis and Beerus find out that Future Trunks used a time machine (that Future Bulma built), Whis mentioned that time travel was against the law of the universe and that humans should not be able to do it. Beerus only refuses to destroy Trunks after Bulma treats him to fish sausages, but Goku Black showing up through a time rift throws a wrench into everything.

Whis explained that time travel is indeed allowed, but only to the Gods. Even his power to turn back time is allowed, but only because it goes back three minutes. Any further than that would ruin the flow of a universe. Which is why Gods are the only ones allowed to go back with the use of a Time Ring.

The Time Ring is a divine artifact that allows a Supreme Kai to monitor a universe or sense disturbances in the time stream (which is why Black was brought to the present temporarily). But even then, Kais aren't allowed to interfere.

So there are definite rules in place for time travel, rules that Bulma and Trunks have broken on multiple occasions. There's also a distinct, proper way to time travel, but as long as Beerus and Whis refuse to interfere Bulma's going to have to be a little tricky.
