Maybe it was the Justice Robot's "death" that was a fixed point of time and space.
River Song and Amy's ragtag group of soldiers were trying to alter a fixed point of time and space. The fixed point of time and space (that they were trying to alter) would by the Justice Robot's "death" (which they presumed to be the Doctor's death.)
In this case, altering the fixed point of time and space (Justice Robot's "death") was disintegrating the Universe!
But then... how would the Doctor and River touching make time move forward? (Of course, presuming that my theory is correct.)
I think that was the uncontroversial point of the gimmick. That all that was fixed was what we saw back at the start of the season: what appears to be the Doctor goes out to Lake Silencio and gets shot by someone in an Astronaut suit, and who or whatever gets shot is burned in a funeral pyre etc etc. So long as those observables occur, the event has not been changed; we've just learned more about the event than we did the first time we saw it. I was honestly expecting the dead Doctor to be a Ganger from the moment those were introduced, especially since as I recall there is still a Ganger Doctor possibly (though not necessarily) in existence somewhere in the timey-wimey ball.
What strikes me as a bigger discrepancy is that in The Impossible Astronaut
the Doctor who died was 200 years older than the Doctor in his present timestream. Which either means that the Doctor's "farewell tour" between the last three episodes lasted over 200 years of his subjective time (and that's a lot of untold adventures), or that the Doctor fake-died 200 of his subjective years earlier than he was supposed to have died. Or, I guess, rule #1* on the Doctor's claim of his age in The Impossible Astronaut
None of that is to mention the nonsensical paradox involved in "creating" a fixed point in time as the Silence did (or tried to do and failed, mayhaps?). If it's fixed, it has always will have be that way (to use the hyperperfect transpresent tense-aspect). It can't ever have not will have been for you to make it always will have be as is implied in the concept of making it fixed; it must not will have been fixed at some time (not necessarily the past) in order for you to make it will have be fixed. (I'm beginning to suspect that someone in the Whoniverse want so get time itself so confused that it just gives up
And the Doctor and River touching makes time move forward because timey-wimey-the-power-of-love-wibbley-wobbley. Would it really make any more sense if the Doctor's real death was what was fixed? River piloted some rigged up astronaut suit and the Doctor piloted some weird time-travelling-shape-shifting-robot-spaceship-with-tiny-people-in-it-thing and one of them made their suit shoot the other suit with a ranged energy weapon. Why should them touching have anything to do with it? What difference would it make if one of them hadn't been wearing said suit?
