But as I understand it from what I've seen from R;N thus far:

Spoiler:

The show is hinting that the sun is about to explode or at least the main character is uncovering top secrete documents that suggest this...so how the hell would Okabe manage to create a world line where the sun is predicted to explode? lol No wonder there are no time machines in the Steins;Gate world line. The sun explodes before they get the chance to. :P
