Question

Is Quantum Foam real?

Answer 1

Answer:

There is no such thing as empty space; there is only 'quantum foam,' everywhere. Such is space-time for a quantum physicist. “Because these bubbles are so small and last for such a short time, they can never be observed directly,” says Perlman. “But they would affect light in an interesting way.”

Explanation:

That something is a roiling collection of virtual particles, collectively called quantum foam. According to quantum physicists, virtual particles exist briefly as fleeting fluctuations in the fabric of spacetime, like bubbles in beer foam. The quantum foam would exist both between the plates and outside of them.
