Life of universe shortened by observing dark energy?

Article in the Telegraph reports on scientists' thoughts on the idea that the life of the universe might come to an end sooner because people are studying it.

New Scientist reports a worrying new variant as the cosmologists claim that astronomers may have provided evidence that the universe may ultimately decay 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 determined that the cosmos is in a state when it was more likely to end. "Incredible as it seems, our detection of the dark energy may provide evidence that the universe will ultimately decay," says Prof Krauss.
