In the perennial search of the meaning of life and the fundamental laws that govern nature, man was always faced – for millennia – with the mysterious concept of emptiness. What is emptiness? Does it really exist in nature? Is emptiness the non-being, as theorized by Parmenides?
Until the early years of the last century, technology had not yet been able to equip scientists with the necessary tools to investigate the innermost structure of matter, so the concept of emptiness was always faced with insights and metaphors that led, over the centuries, to a broad philosophical debate.
For the ancient atomist Greek philosophers, the existence of emptiness was not only possible but had become a necessity, becoming the ontological principle for the existence of being: for them, actually, the emptiness that permeates the atoms is what allows movement.
