Have we inadvertently killed Schrodinger’s cat? No, it’s much, much worse. Cosmologists at Case Western Reserve and Vanderbilt speculate that mankind may have hastened the end of the universe by observing dark energy in 1998. “[Q]uantum theory says that whenever we observe or measure something, we could stop it decaying due what is what is called the ‘quantum Zeno effect,’ which suggests that if an ‘observer’ makes repeated, quick observations of a microscopic object undergoing change, the object can stop changing – just as a watched kettle never boils…Prof Krauss says that the measurement of the light from supernovae in 1998, which provided evidence of dark energy, may have reset the decay of the void to zero — back to a point when the likelihood of its surviving was falling rapidly. ‘In short, we may have snatched away the possibility of long-term survival for our universe and made it more likely it will decay,’ says Prof Krauss.” D’oh! But wouldn’t this presume that at no other place or time in our unfathomably gigantic universe did any other civilization make the same observations? Given the odds of intelligent life out there, that seems unlikely. (And, if you think this all sounds goofy and ridiculous, just wait until we get to the multiverse…)
