The artist of the empty space is Salvatore Garau from Italy. This is what he said about the expensive void:
The successful outcome of the auction testifies to an irrefutable fact: The void is nothing but a space full of energy, and even if we empty it and nothing remains, according to Heisenberg’s uncertainty principle that nothingness has a weight. It, therefore, has an energy that condenses and transforms itself into particles, in short, in us! When I decide to “exhibit” an immaterial sculpture in a given space, that space will concentrate a certain quantity and density of thoughts in a precise point, creating a sculpture that from my title alone will take the most varied forms. After all, don’t we give shape to a God we have never seen?
