As most who have read my posts know that I believe that they could dial Destiny from the Ori gate.
Now someone correct me if I'm wrong, but has it not been stated all through out the Stargate Franchise that while matter can only travel one way through a worm hole, energy such as a radio signal or even explosive force can be translated in both directions through the Gates. With this in mind I'm think I've come up with a way to bring the crew back via the Ori gate being dialed from the MW side.
The Asgard transport beam converts matter in to energy for transport, so they could beam the crew back through the gate even if dial from the Milky way since they would be converted to energy before hand and converted back after they arrived on the ship in the Milky way.
What do you guys think of my idea?
