Persistent Universe

Antarix universe is made up of many sectors that are dynamic, it's not hard coded in game, so planets can be harvested fully, terraformed or fully destroyed with large weapons that can be created by empires/factions only. Divided in sectors, each sector is a solar system in itself. Its persistent that means whatever changes you make to the universe like make a base somewhere, this base can be seen and visited by other players, in the later releases of the game other players can also loot your bases if they want, so you have to also defend those, even if you are not playing your bases remain there. Same goes for ships, if you don't park your ship to safety it's basically a sitting duck when you leave them in open, It's recommended to make a base somewhere on a planet and park your ships, vehicles there.
