[Stargate] why don't they use the time travel ship to return to the time of the Ancients?

I haven't finished the series, however you would think the first mission they would use it for would be to return to the Ancients time and acquire knowledge and technology. The entire purpose of an SG team is to acquire advanced technology and nobody is more advanced than them.

Well, firstly, you don't fuck with time travel. They have fucked up the present several times, and only use time travel if they really really need to. Secondly, the time machines themselfs are often unreliable, considering they are 10 000 years old.
Thirdly, the ancients wouldn't react kindly to it. We have seen the times ancients have returned, they didn't care much about the tauri. If you go to the past they might not let you leave.
