Utilitarianism
In the situation where the world will end but there's a way to stop it, and most people don't believe the world will end except one person who knows it will, actually also knows how to save it and they're the only one that can do it. Now, add in the fact that everyone else in the world thinks they'll be fine and happier if the person doesn't save the world (possibly becuase the process involves something weird/unpleasant), and hence, don't want them to save the world, which is the more utilitarian? Listening to these people and letting them all die (unbeknownst to/ignored by them), or ignoring these people and letting them all live (in the sense that they believe they will regardless becuase the end of the world is hokum to them)?
Assume everyone wants to live (in general).
Edited for clarity.

Huh?
There are so many conditions in your hypothetical situation, and only two answers to choose from, that it seems you want others to come to only one conclusion.
Why don't you just tell us which conclusion it is, and let us get on with the discussion?

The title of the topic is utilitarianism, so the answer is quit simple from that perspective. Namely save them all, since in that scenario the most humans survive. Also nothing has been written about how the world would be saved, only that it might be weird or unpleasant. And these kind of scenarios it is usually more established what needs to be done, like kill one person to save two. So there is not really a dilemma here.
