Shadows of the sky

Thinking about neutrinos, I also came across this:

This light tells us much, but I think in the course of time still more delicate and subtle mediums will be found to exist, and through these we shall see into the shadows of the sky.

A new idea of reality

Richard Feynman once suggested that nature is like an infinite onion. With each new experiment, we peel another layer of reality; because the onion is infinite, new layers will continue to be discovered forever. Another possibility is that we’ll get to the core. Perhaps physics will end someday, with the discovery of a “theory of everything” that describes nature on all scales, no matter how large or small. We don’t know which future we will live in. But the observation of neutrino masses tells us that the adventure of discovery in which we are currently involved will not end here. There are still fundamental mysteries to be resolved.
