yes, to put it simply. if you look in your civ research tree, there is a wormhole travel item. this must be researched before you can use wormholes. to use a wormhole itself, right click the center of the wormhole - anywhere in inside the interior ring - to move your ships through it. if you are tracking a ship (zoom into one or double click the icon - not the ship - so you are following it w/out you moving the screen) then you will folllow the ship through the wormhole. after it has been used once, you can click the wormhole and a thick line will lead to the other wormhole it goes to.
