[Rant] *sighs* Who told you I have portals? No we use traditional luminal spacetravel (closer to 2.5 million mps, not to be confused with going at constant c) and superluminal, we accelerates though spacetime in an vacuum, going boosting and calculating every close and safe route with multiple fortresses in the vast space, moreover our starships has sort like mechanical system that cheats the speactime fabric into causing the ship to house it's own realitivistic time, kind of like outside is storming while the ship inside is normal as usual. How do we accelerate towards light? Using gravity and Krasnikov tubes. An average Jansanian starship typically navigates through stellar systems, utilising gravitational assists from nearby stars to gain acceleration and cover short distances, particularly within inner star systems. However, as superluminal space travel technology continues to advance, Jansanian quantum physicists and metaphysicians are increasingly captivated by cutting-edge spacetime metrics, leading them to explore the potential of Krasnikov tubes. Since the era of Jansan II, numerous tests have demonstrated varying degrees of success, allowing researchers to gradually evolve from conceptualising affordable transportation to establishing a network spanning the entire galaxy. Although Krasnikov tubes present the challenge of requiring exotic matter with negative energy density to effectively warp spacetime and maintain their structural integrity, they represent a significant leap forward in facilitating nautical space travel, enabling humanity to explore the vast cosmos with greater efficiency. In the case of communication, we use quantum entanglement by encrypting a string of information to a series of quantum entanglement machines. Seven decades ago, quantum physicists, after countless years of analysis, figured out the encryption key of quantum entanglement, and it's no longer a paradox. Along with Bell's theorem, long distance communication is possible.
Concrete postulate you have to consider: I. Relative long distance and time consuming not the same theoretically. II. The Jansanian treasury is vast. (The rest is personal) III. I can anathematize if you are in the files. IV. I have biceps and triceps. V. Please join my blu app fanbase server. Server code: AZfWaWPum
