>>34099576To be fair Ult.N, kinda comes from another universe where those factors seem to hold no rules it follows considering multiverse theory make the concept of time pointless and space is utterly warped. So it may live outside those constructs where it can go anywhere with light bending to it's will. Light is also mass-less.
Dialga and Palkia's powers are probably only limited to their universe.
Giratina is limited to his own miniverse, which helps prove why Giratina is the star of the 3 because it too lives outside the factors of Palk & Dial's powers being a universe of a differing set of rules.
