German researchers hoping to be the first to successfully measure quantum flickering directly in a completely empty vacuum are setting their sights on 2024.

If successful, the first-of-their-kind experiments are expected to either confirm the existence of quantum energy in the vacuum, a core concept of quantum electrodynamics (QED), or potentially result in the discovery of previously unknown laws of nature.
