I recon this has been done before, but its not on any of the recent pages so I thought I'd give it another go.
So we know that Destiny is aiming for the centre of the Universe to find "The God Signal" Or as Rush would say a sign of intelgence at the time of the big bang.
How obvious is it that the signal they are going to find is them, as they will have no doubt completed Destiny's journey, been somehow present at the beginning of known time and space, and for reasons that will have been explained sent a signal to tell themselves something.
I'm usually pretty good at guessing outcomes of plots in novels and movies. And this seemed too obvious!
Guess we'll never know for sure though...... Dam it, I love being right!
