The weird & the wonderful

Quantum Mechanics is based on probabilities and duality whereby a subatomic particle can be a wave or a particle depending on how said entity interacts with its environment, including on whether said entity is measured or not because measuring it (which requires energy) determines whether it's a particle or a wave at the time it's being measured.

Our general logic would assume that the object is either wave-like or particle-like by its very nature, and our measurements will have nothing to do with the answer. But quantum theory predicts that the result all depends on how the object is measured at the end of its journey. And that's exactly what a team from the Australian National University has now found.

"It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it," lead researcher and physicist Andrew Truscott said in a press release.

To yours truly, the experiment is wonderful but saying reality does not really exist is misleading as the entity does exist as a duality and only by applying energy to it by the act of measurement do we assign a specific state of the entity to either being a particle or a wave. This fact has been known for a long time but this elegant experiment proves this to be true without question.

Weird & wonderful indeed. :)
