Wigner's Friend paradox
It's Impossible To Tell If This Story Exists, According to Quantum Physics
Blame it on the Wigner's Friend paradox.
This paradox is well-known in physics circles as the Wigner's Friend thought experiment, and it supposedly proves that you cannot assume the knowledge of other observers as your own. But a team of researchers from the University of Vienna, the Austrian Academy of Sciences, and the Ontario-based Perimeter Institute for Theoretical Physics have proven that the full story is even more complicated: you cannot even trust your own eyes.
