Theodore Hm... It isn't activating... It's almost as if it requires a special access code in order to activate the gate, and unfortunately, you don't have it. You can walk and try to enable it manually, however that will probably take a few months, since the tech is so advanced (not out of reach, though) that it will take your scientists a few months to understand how to activate it properly and not blow it up.
However, it seems you won't need to do that because while you were waiting, SOMEONE transmitted an access code to your end of the gate. You don't know who, but you won't have to wait long to find out, as the mechanisms of the gate started activating and a bridge through space and time started forming, and you can see it slowly becoming larger in front of your very eyes.
