- Small things go many paths, go as things or waves. What is the largest thing that has been observed or if not yet observed, is considered possible to observe.
Back when the world was experimenting with radio it took significant advances in technology to gain the benefits. As we are just getting into the Quantum world I wonder if we can ever see something with our own eyes. I wonder where the line must be drawn and how technology can move that line. We do not see which slit the wave travels, but it does. What happens in the larger world that we also do not see, but they happen.
