The Galactic Nexus is the vast web of tachyonic networks that is essentially a large-scale "internet" of the galaxy. Local Internets done via electromagnetic communications send signals to local tachyonic communication arrays that relays the messages across the numerous relays in the galaxy, allowing communication to other civilized races and territories. The Nexus has sparked a unique culture shift as people across the galaxy could communicate, leading to the creation of many websites indexed by search engines. The most popular search engine, NexSearch, was created by a Hylotl communications company called Ryujias Conglomerate, and uses an advanced form of the search algorithm created by the Human company “Google” over a millennium ago to rank Nexus searches based on links and popularity. Many user-created servers have emerged since the establishment of the Nexus; most Civspace sites utilize standardized domains, followed '.nex' to indicate their presence as a galactic website, though typically the Civspace domain is omitted.
The Nexus utilizes a series of standardized protocols that must be utilized by every relay in its vast tachyonic network. These protocols function similar to the TCP/IP protocol used in real life internet. The Nexus is designed to be as decentralized as possible so that any tachyonic relay can be made and used in the network.
A tachyonic relay is necessary for a device to communicate with the nexus. Devices such as phones, computers, drones, etc. utilize advanced radio transmitters and receivers to establish a connection with the tachyonic relay like your device establishes a connection with your home's router. The relay acts as an interface between you and the Nexus, receiving radio packets from your phone and beaming them out across various relays until the tachyonic packet reaches its destination. It works the other way around as well, decoding tachyonic packets and sending them back to your device's radio receiver. It should be noted that devices may not necessarily connect directly to tachyonic relays, and may sometimes do so through a colony's local ‘intranet’ of electromagnetic communications, much like the global internet today.
Much like modern communications, each device has an assigned ‘IP’ address that is used to direct packets to it (in the 33rd century, it is called a ‘NP' address for ‘Nexus Protocol’.) Unlike modern devices however, NP addresses are dynamically assigned upon a successful connection to the local tachyonic relay, which has its own static NP address that it uses to receive packets from other relays. NP addresses are designed to be of arbitrary length due to the potentially vast number of addresses that must be assigned by a relay, and are designed to be easily converted to quantum bits. Most relays utilize quantum computers due to the vast computational requirements they need to process a vast number of packets from any given source; quantum computers also allow relays to index a device's assigned NP address in quantum memory for instantaneous access where there may be the addresses of potentially millions of different devices in memory.
