Empty

/ˈɛmpti/adjective / verb
ELI5 Mode🧒

Empty describes something that lacks contents, substance, or occupants, like an abandoned room or a blank page waiting to be filled. In modern contexts, it can extend to emotional or digital realms, such as feeling an inner void after a loss or dealing with an empty file in computing, reminding us how absence can be as powerful as presence.

In quantum physics, what we call 'empty' space isn't truly empty at all; it's buzzing with virtual particles that briefly appear and vanish, as demonstrated by the Casimir effect, which measures the force between two uncharged plates in a vacuum. This revelation from the 1940s experiments challenges our intuitive grasp of emptiness and shows that even nothingness is full of activity.
