In #specialrelativity two events separated by a space-like spacetime interval are so far apart that even light can’t travel from one to the other in time to connect them causally. Because of this, different observers, moving at different velocities, will disagree about which event happened first, or may even see them as simultaneous. This doesn’t mean causality breaks down, though: events that can influence each other (those with time-like or light-like separation) maintain the same order in every reference frame, preserving the universe’s underlying cause-and-effect structure. #V6
