ABSTRACT
In the previous chapter, we saw that rather than thinking about reality as a static state, it may be helpful to think of it as a process, and perhaps even a process in which the observer participates: she has an active role in determining what is observed. This is certainly true in quantum physics, where quantum superposition is not resolved until a measurement is made. Our classical way of viewing the world leads us to interpret it as being much more absolute at the (larger) scale at which we live our lives. But, as we saw in Chapter 4, quantum processes play much more of a role in our daily lives than we typically realise. For example, entanglement, where two quantum systems interact immediately irrespective of their distance, is a central concept in quantum physics. Yet it appears to defy causality, as we are used to defining it (where one event causing another must always precede it). Erik Verlinde said the following about quantum entanglement:
