In the interstellar realm, this is undoubtedly extremely clumsy and sluggish.
In the war that led to the extinction of the Worren Civilization, even the expedition teams they sent out failed to transmit any messages back before losing their civilization.
Yet, even for civilizations that have initially mastered space teleportation technology, teleportation is not possible anywhere at any time; they must first reach the points of spatial weakness, known as "nodes."
Cosmos space is not flat; rather, it has a certain curvature, which can be imagined as a large curved membrane. This is the basic principle of curvature navigation.
However, this "membrane" is not only a single curve.
It possesses continuous, irregular undulations.
Once a curvature becomes too large, it may make contact with another space with equally large curvature.
These points of contact are the "nodes."
They are the distance units used in interstellar society.
