when an entity is having properties of both particle and a wave you cannot use classical mechanics to calculate things like momentum and so one. there is a mathematically proven instance where that even mass doesn't exists for very small time period(yang mills mass gap). in every qunta moment energy levels changes, property of the entity changes, so basically you cannot predict the next stage of an entity when it comes to quantum world. some particle doesn't even exist for even quanta mili seconds, if you know about higgs bososn you will know what im talking about. in switzerland they are spending 8 billion to observe unidentifiable entity. that's some other story. scientists are trying to develop a method to to these classical world calculation in this quantum world. it is called second quantization.
but basically it is like this as lord buddha told there are no constants everything changes in every mili nano quanta second. nothing is connected. there no me or you. what we have is constantly changing energy flow.
