**We all know that the quantum world is weird, but just how weird is it that the future can affect the past?**

**Indeterminacy is the fact that in quantum mechanics, no matter how much you know about a quantum particle, you can't predict its quantum state until you measure it. Instead, what quantum mechanics provides is the statistical probabilities of a particular state.**

**This is best summed up by Schrodinger's famous cat in a box, who is in a superposition, being both alive and dead, until the box is opened.**

**A particle's state is not just unknown, it is truly undetermined until it is measured. It is the act of measurement itself that forces the particle, or cat, to collapse to a definite state.**
