Oops, our bad: by observing the universe, we may have doomed it

DarkMatterPie-590 One of the weirdest aspects of quantum theory is the role of the observer: particles exist only as probabilities until they are observed, at which point they become definite. (Schrödinger’s neither-alive-nor-dead cat is the most famous thought experiment along these lines.) (Via EurekAlert!)

Now New Scientist is reporting that a pair of physicists at Case Western Reserve University in Cleveland, Ohio, suggest that when, in 1998, astronomers observed the light from supernovae and from that deduced the existence of dark energy, we may have reset the clock of the university universe to the state it was in early in its history, when it was more likely to just as suddenly cease to exist as it suddenly sprang into existence in the first place.

We’re still here, so the universe hasn’t winked out of existence just yet. But any second now…
