The yuuzhan bong use it

[i]No, they didn't. Now you're just making things up. [/i]

No they use something other than hyperspace. Also what is the difference between hyperspace and slipspace

[i]Can you prove they use Slipspace, though? No, you can't, because Slipspace doesn't exist in Star Wars. Hyperspace is essentially making your ship travel really fast along a predetermined Hyperspace lane. Ships cannot enter Hyperspace while they are close to a gravitational field, and they can smash into another object, like a planet or a star, while traveling. Slipspace travel involves tearing a hole in reality and moving through an 7-dimensional plane. Ships utilizing Slipspace are not limited by gravitational fields, and so can enter Slipspace within a planet's atmosphere. Furthermore, ships traveling through Slipspace are not in our reality, and so they don't need to worry about running into celestial bodies. In short, Slipspace is better than Hyperspace. [/i]

WHY THE -blam!- ARE YOU TYPING IN ITALICS!

They do the same thing. Forerunner slipspace can tear a hole in reality but not something like the UNSC engine which shortens the physical distance. It takes months to cross across the galaxy with a slipspace engine yet it takes hyperspace only a few days. The Rakatans created hyperspace feuled on a planet's force potential. A missile able to go as fast as to bend reality with hyperspace would go strait through a ship in slipspace.
