Don't even think.

[C]osmologists claim that astronomers may have accidentally nudged the universe closer to its death by observing dark energy, a mysterious anti gravity force which is thought to be speeding up the expansion of the cosmos.

The damaging allegations are made by Profs Lawrence Krauss of Case Western Reserve University in Cleveland, Ohio, and James Dent of Vanderbilt University, Nashville, who suggest that by making this observation in 1998 we may have caused the cosmos to revert to an earlier state when it was more likely to end. “Incredible as it seems, our detection of the dark energy may have reduced the life-expectancy of the universe,” Prof Krauss tells New Scientist.

Ignorance, by this analysis, is not so much bliss as longevity. Or, at least it would seem so I suspect. It's a good thing that the singularity is near, or in progress, so that we can deal with these cosmic issues with brain power more equal to the task. Or will that make it even worse? Well, that's - by definition - beyond me.
