... the ... most literal take on quantum physics, often called the Copenhagen interpretation, is what you're most likely to encounter in a physics classroom. Yet it has rankled physicists as eminent as Albert Einstein. To these thinkers, the Copenhagen interpretation amounts to an argument that the world ceases to exist the moment you close your eyes, or that page 100 of the novel on your nightstand remains blank until the moment you turn over page 99. In other words: It just doesn't smell right.
So how did it fare in the poll? It came out on top, with 42 percent of the votes. The information interpretation, which suggests that information, not matter or energy, is the fundamental "stuff" of the universe, came in a distant second, with 24 percent. Close behind in third, at 18 percent, was that sci-fi favorite, the many-worlds interpretation, according to which every quantum measurement actually splits the universe into multiple, parallel universes.
"Other" and "no preferred interpretation" tied for fourth place, with 12 percent apiece. (Yes, eagle-eyed readers, something fishy is going on with the math here: Respondents were allowed to vote for more than one choice.)
You might say, then, that the Copenhagen interpretation is on the decline. Though Copenhagen has been around since the 1920s, the many-worlds idea didn't arise until the 1950s, and quantum information theory is an even later entry into the race, suggesting that physicists are hungry for new ways of thinking about quantum mechanics.
