According to theory, there are countless electric dipoles created by virtual particles in any given volume of the quantum vacuum.
这个理论告诉我们，在任何给定体积的量子真空中都存在数不清的由虚粒子产生的电偶极子。

According to quantum physics, empty space is not actually barren but is a boiling sea of so-called virtual particles and antiparticles constantly popping in and out of existence.
量子物理学认为，真空并不是真正是空的，而是沸腾的海洋——被称作虚粒子与反粒子的东西不停出现与消失。

The virtual particles spontaneously created in the quantum vacuum appear and then disappear so quickly that they can't be directly observed.
