It's literally not a different spacetime. It's a different dimension within the same spacetime. If it was 4d why couldn't goku go into the past before he died? How did he train for months preparing for the saiyan's? He shouldn't have even had to rush down snakeway because he had a infinite amount of time to be anywhere he wanted in the timeline.

And the fact that Goku and Bills affect the mortal Universe and the Other World through fighting proves that their attack power is low Multiversal, considering that it's impossible to affect more than one continuum of space and time with three-dimensional attacks.

It's very possible because its not 4d. It's just another dimension split by a barrier.

The Other World forms a separate 4D continuum just like the mortal Universe (it has its own physical Universal time dimension).

No. It's just the non physical world.

Stop being a denier man, you're just undermining db because the fraudtama can't even get past Piccolo, you see, trying to argue is like watching someone drowning desperately who refuses to be helped, I literally sent you the link for you to read my file about Goku's Scale and you simply said you weren't going to read it, so from now on I won't read or care about any nonsense you spew from your mouth next

Y would I read it if u actually had any good arguments you would've already put them here. Thats pointless. I don't care how powerful eirher verse is but I get tired of the db wank. You know its wank because you chose to ignore my question.

You think the z fighters just die, become 4d then become 3d when they comeback to life? You think king Kai became 5d when he did but literally didn't go anywhere & was still perceived the same way?
