A recent study suggests that, at least in the quantum world, two versions of reality can coexist. Researchers have tested a theoretical physics question that was posed as a simple thought experiment decades ago.
Within the concept, two imaginary scientists are both deemed to be correct, despite arriving at totally different conclusions. It implies that there is no such thing as objective reality and raises fundamental questions about physics if this is proven in practice.
A British team at Heriot-Watt University published the findings on arXiv, a website for research that has not yet undergone full peer review.
They set out to explore “Wigner’s friend”, named after Nobel prize-winning physicist Eugene Wigner who came up with it 1961, which is based on the idea that a photon, or a particle of light, can exist in two possible states.

Two contradictory versions of reality exist simultaneously in quantum experiment, scientists suggest
The research, conducted by a British team at Heriot-Watt University, puts to the test a theoretical physics question known as "Wigner’s friend."
