Forum:Galaxy to Galaxy Gate Travel

I'm just catching up on the last 3 seasons of Atlantis and something is niggling at me. If there is already an answer in the wiki I apologise but here is what I am not sure of.

The Gate Bridge between the Pegasus and Milky Way galaxies was built for fast travel between galaxies without the need for a ZPM or a ship capable of inter-galactic travel. I already know that the Atlantis gate is the only one in Pegasus capable of dialling earth becuase of the additional control crystal in the DHD.

Was this a design element that the Ancients/Lanteans built into the Pegasus gates to protect the Milky Way (and other galaxies) as already seen on SG1 twice the SGC, a Milky Way Network gate is capable of utilising the 8th Chevron without a problem to get to ther galaxies without the need for a special additional control crystal or dialling command(once to get O'Neill to the Ida Galaxy and the 2nd time to geth the Atlantis Expedition to Atlantis itself)85.189.162.25 21:08, 16 March 2009 (UTC)
