The concept of traveling through dimensions is largely speculative and rooted in science fiction rather than established scientific principles. However, if we consider the hypothetical existence of extra dimensions beyond the three spatial dimensions we are familiar with (length, width, and height), there is no inherent requirement for time travel to be involved in dimensional travel.
In popular culture and fiction, traveling between dimensions is often depicted as involving some form of portal, wormhole, or other exotic means. These fictional portrayals often do not explicitly connect dimensional travel with time travel. Instead, they propose that by manipulating the fabric of space or accessing higher dimensions, one could move between different realms or parallel universes.
It's important to note that the understanding of dimensions and their relationship to time is still an area of active scientific investigation and theoretical exploration. The prevailing physics theories, such as string theory and M-theory, suggest the existence of extra dimensions, but the specifics of dimensional travel and its separation from time travel remain speculative.
Until there is concrete scientific evidence or advancements that provide a deeper understanding of extra dimensions and the possibility of dimensional travel, it is considered purely hypothetical.
