Does the world we live in exist? Scientists say no – at least not until it’s measured anyway, and this would pertain to small scale. For Australian scientists, recreating experiments confirmed quantum physics’ predictions. The existence of reality is questionable.
If this sounds complex, not to worry. This experiment poses one simple question: Since some elementary particles act as a particle or a wave, then when is this classification decided? This question pushes us to understand how reality is established.
Most people assume that objects such as electrons or photons either wave-like or particle-like just because that’s the way it is. They think that measurements aren’t necessary to come to either conclusion. Quantum theory disagrees and suggests that conclusions can only be made by measurements taken at the end of the object’s journey.
