If there is no inherent left or right in the universe, determining the "correct" side of a wormhole becomes a challenge. However, it's important to note that wormholes are purely speculative structures in theoretical physics, and their properties and behavior are not yet fully understood or proven.
In theory, a wormhole is a hypothetical tunnel that could connect two distant regions of spacetime, potentially allowing for shortcuts or travel between them. If we were to consider the possibility of using a wormhole as a time-tunnel, determining the correct side would depend on the specific properties of the wormhole and the nature of time travel within it.
One approach might be to establish a reference frame or coordinate system within the wormhole itself. By defining a consistent set of coordinates or using a specific method of navigation, travelers could determine which side of the wormhole corresponds to their intended destination in time.
However, it's important to recognize that the concept of time travel and the behavior of wormholes are still highly speculative and theoretical. The current understanding of physics does not provide a definitive framework for using wormholes as time tunnels, and many fundamental questions and challenges remain unresolved.
