Groundbreaking new study claims to prove more than one reality exists

Express UK | April 27, 2019 | By Carly Read

Scientists claim to have proven there is more than one reality thanks to a groundbreaking new study.

A new piece of research suggests that at quantum level there are actually two versions of the same realty. It also touches on the complex idea two people are capable of coming to different conclusions about the same photon, a particular type of particle, and that both can be correct in their observations, as Fox News reports. The theory attempts to prove that the resulting statements of the two observers are unable to contradict one another. The study reads: “In quantum mechanics, the objectivity of observations is not so clear, most dramatically exposed in Eugene Wigner’s eponymous thought experiment where two observers can experience fundamentally different realities.

“While observer-independence has long remained inaccessible to empirical investigation, recent no-go-theorems construct an extended Wigner’s friend scenario with four entangled observers that allows us to put it to the test.

“In a state-of-the-art photon experiment, we here realise this extended Wigner’s friend scenario, experimentally violating the associated Bell-type inequality by 5 standard deviations. This result lends considerable strength to interpretations of quantum theory already set in an observer-dependent framework and demands for revision of those which are not.”
