The wormhole used by the Solar System, is a pseudo-wormhole, claimed to be their own technology. In fact, humans do not possess the ability to create wormholes. The leap to Kepler was not a creation, but a discovery. The latent wormhole has always been there, moving along with the Solar System, causing intense debates. The Solar System's eight major planets are constantly advancing in the universe following the Sun, and the wormhole coordinates also move along with it, the relative coordinates always unchanged. This positioning ability is something current humans cannot explain. However, mankind cannot stagnate due to the unknown.
From a different angle, it can also be seen as a target coordinate. When we discovered the Kepler coordinates, the conditions for opening the wormhole and making the transition were mature.
