Does 'empty' space have mass which is displaced by matter?
So, does that mean 'empty' space itself has mass?
Well, it's not exactly mass in the traditional sense, but it does have energy. According to quantum field theory, even empty space is filled with virtual particles that pop in and out of existence. These fluctuations contribute to the energy density of the vacuum, which can be thought of as a kind of "background energy" that permeates the universe.
