As bizarre as it may sound, a new quantum physics experiment by physicists from Heriot-Watt University in Edinburgh has suggested that objective reality may not exist after all. While this idea was once only a theory, it has now been taken into the lab and tested.
As Science Alert reports, the new experiment has shown that in the world of quantum physics, two different people can witness the same event occurring and note different outcomes, and neither of these two perceived events may be incorrect.
The physicist Eugene Wigner was the first scientist to hit on this topic when he suggested back in 1961 that one of the odder thought experiments in quantum mechanics involved the idea that two individuals, in this case Wigner and Wigner's friend, could observe two different realities, with neither individual technically being wrong.
Since this thought experiment in quantum physics was first proposed, physicists have called this theory "Wigner's Friend," and have sought to determine for themselves whether objective facts really exist in life. Because objective facts can theoretically be proven by scientists in a laboratory, it makes sense that they would be important.
However, according to this thought experiment, if two people see two different realities taking place, it would be quite impossible to agree on which one is seeing the correct reality.
