The article discusses the lack of causality in quantum mechanics, suggesting that a measurement made a certain type of action after a certain object was sent through a device that could either be seen as a particle or a wave. This raises questions about whether causality even exists in quantum physics. Researchers have been exploring this issue further in detail using an experiment that suggests it is possible to create quantum superposhes between two events, making the question of whether A or B happened first. The researchers believe these loopholes could be eliminated.
