Solar Systems and Wormholes

• Solar Systems
  Everything that you see on a map is in the same solar system. To travel to another solar system, you will have to slide your ship through a wormhole. All objects in a solar system orbit the sun in an XY plane, there is no Z (up/down) movement.
  
  
• Wormholes
  According to Stephen Hawking, a wormhole is a thin tube of space-time connecting distant regions of the universe.
  
  
  • Sliding your ship through a wormhole will take you to another solar system, or possibly another point within the same solar system. Sliding through the wormhole a second time should take you back to your point of origin.
    
    
  • Wormholes move, which means that there is no permanent map of the Star Exodus universe; the geography is changing continuously. The ends of wormholes can move in two different ways: within the XY plane of a solar system, or to another solar system.
    
    
  • Wormholes can move rapidly, or move so slowly that they appear stationary. Wormholes can also move at different speeds within a solar system than they do between solar systems. In other words, a wormhole might move rapidly within a system, but remain in that system, or a wormhole might remain at a specific distance from the sun, but move from system to system rapidly.
    
    
  • If a wormhole moves away from you, you may have to find another route home.
    
    
  • Most wormholes can be used by any spaceship, but some wormholes can only be detected by a specific race's ships. This means that each race travels in the same universe, but using a separate geography.
