Th e newest frontier turned out to be right beneath our feet the whole time. More importantly, we’ve come to understand that this new state of being is the key to exploring the cosmos. Our first attempts, while successful, were met with disaster. Unsurprisingly, when you shrink something with the mass of a human to a microscopic scale we tend to sink through most materials. Those early objects were all lost. We moved to make strong platforms for the reduced items to stand with success. When we moved to animal experiments, learning that the increased mass made basic body functions impossible.
