“The Universe Knows It Is Being Watched”

University of Vienna Professor of Physics Anton Zeilinger is working on quantum experiments that demonstrate the influence of observers in shaping reality. He believes physicists have only scratched the surface of something much bigger and says, “Maybe the real breakthrough will come when we start to realise the connections between reality, knowledge and our actions.”

Zeilinger and others working in the field have shown that widely separated particles can somehow have quantum states that are linked: by observing one, the outcome of the other is affected. But as New Scientist magazine says, “No one has yet fathomed how the universe seems to know when it is being watched.”
