Quantum theory is remarkably consistent and beautiful. Yet, as a theory on an experimental science, it ought to tell us what is measurable and how to extract information about Nature from these measurements. It also ought to tell us how Nature produces correlations between disconnected regions that can’t be described using only local variables that propagated gradually and continuously through space. Staring at these two problems might not help to find the next theory. But it provides much inspiration to design experiments that illuminate the situation and might, some day, help in finding the limits of quantum theory. I’ll discuss these two problems and their different status. Next, I'll present several such experiments.
