These fluctuations in energy often take the form of matter/antimatter pairs of particles spontaneously “popping” into existence from otherwise empty space. These pairs of particles, called virtual particles, travel finite distances through space during their brief lifetimes and have repercussions that may influence the ultimate fate of the universe.
