Does the truth exist when we are not looking?

The standard interpretation of quantum mechanics places a lot of emphasis on the act of measuring. Before scaling, quantum systems exist in many states simultaneously. After a measurement, the system “collapses” to a set value, so it’s only natural to ask what’s really going on when measurements aren’t made. There is no clear answer, and the different ideas can go in some really wild directions.

One of the first lessons physicists learned when they began examining subatomic systems in the early 20th century was that we do not live in a deterministic universe. In other words, we cannot accurately predict the outcome of each trial.
