The universe does not exist if no one perceives it any longer. That suggests at least one popular theory in quantum mechanics. According to the theory, the state of a particle changes as soon as it is detected.
Scientists have done an experiment to prove this theory correct. According to the laws of quantum mechanics, there is no clear boundary between the outside world and our subjective consciousness.
When physicists look at photons or atoms, their perceptions will be affected by their experiment. To test this, physicists at the Australian National University recently did the thought-experiment by John Wheeler.
During the experiment, the moving object was given a choice in order to behave like a particle or as a wave. At what point the object makes the choice? You could say that the state of the object is not dependent on the measurement done by the scientists.
Quantum mechanics, however, predicts that the behavior of the object will depend on the way it is measured at the end of his trip. “Everything is about the measurement,” said Professor Andrew Truscott. “At the quantum level, the reality does not exist if you do not look at it.”
If you assume that an atom takes a certain path you must accept that a future measurement is influenced by the history of the atom, said Truscott.
“The atoms did not go from A to B,” he said. “Only when we did a survey at the end of the ride they acted like wave or as a particle.” The research was published in Nature Physics.
