The universe is bustling with matter and energy. Even in the vast, apparent emptiness of intergalactic space, there’s one hydrogen atom per cubic meter. But is there such thing as a total absence of everything? Is it possible to make a completely empty space? Rolf Landua and Anais Rassat explain the science behind vacuums.
