Question about space-time continuum and other things

[Extreme123dz]

So, whats means space-time continuums? whats is exactly, destroy the Space-Time Continuum is a 4D feat and if is, why?


Also:

- if a Character can destroy the Universe and The Time-Lines (Linear, or branched) disapear or cease to exist as a Side effect/Cause fo the UNiverse is destroyed, what AP/DC is?

- If a Character Destroy the Universe whit The Time-Lines (Linear, or branched and each is independent), what AP/DC is?

- If a Character destroys the UNiverse/s (Linear, or branched and each is independent) and the same times, all parallel UNiverses/Dimensions (what ever the size) caese to exist as an Side Effect / Casualitie, What is on AP/DC?

I'm sorry if my questions are not well understood e.e
