Multiple Realities Confirmed At A Quantum Level In A New Experiment

It appears that the multiple realities theory is, in fact, right, at least when it comes to quantum physics. According to researchers, two versions of reality can exist at the same time at the quantum level.

Physicists conducted experiments to test this theory. They tried to discover whether two individuals can observe the same photon and have different conclusions about its state. The results of the experiment were published in the preprint journal arXiv.

The experiment confirmed that two states of the same photon could be observed at the same time by two persons, both observations being correct. “You can verify both of them,” said study co-author Martin Ringbauer, who is a postdoctoral researcher with the Department of Experimental Physics at the University of Innsbrück in Austria, told Live Science.

A new experiment proved the existence of multiple realities at a quantum level

This idea was formulated in 1961 by Eugene Wigner, who is also the winner of a Nobel Prize for Physics. The thought experiment was known as “Wigner’s friend.” Nonetheless, this remained simply a thought experiment for decades, up until now. “Theoretical advances were needed to formulate the problem in a way that is testable. Then, the experimental side needed developments on the control of quantum systems to implement something like that,” Ringbauer explained.

Ringbauer had two laboratories for the experiment and doubled everything by introducing two pairs of entangled photons, which would mean that the state of one of them would also be the state of the other. There were also four participants, two in each lab, namely, two experimenters and two “friends,” or observers.

The experiment proved that the results described by Wigner held. “It seems that, in contrast to classical physics, measurement results cannot be considered absolute truth but must be understood relative to the observer who performed the measurement. The stories we tell about quantum mechanics have to adapt to that,” Ringbauer concluded. In short, scientists proved that multiple realities exist at a quantum level.
