What does imploding mean?
Imploding means collapsing or exploding inward. The physical sense describes a material force or object moving toward its centre, as with an imploding star, an imploding container, or a structure that caves in. In figurative contexts, it applies to rapid and severe contraction, such as a market imploding as prices fall or an organization imploding when its financial and institutional support disappears. The word is also used attributively, as in “imploding universe” or “imploding finances.” Compared with the more general word collapsing, imploding suggests an especially sudden, concentrated, or explosive inward movement. It is usually negative or alarming in tone, although astronomers also use it neutrally to describe stars and other astronomical objects whose inward collapse has important physical consequences.
To explode or collapse inward.
"The hollow structure imploded under the pressure."
Often transitive when something makes the object or system collapse inward, as in “the scandal imploded the organization”; it can also be intransitive.
Collapsing or contracting sharply inward, especially as a result of extreme pressure or loss of support.
"Astronomers observed an imploding star in a nearby galaxy."
Common in technical and figurative descriptions such as “imploding universe,” “imploding market,” and “imploding finances.”
An imploding star does not blow apart in the ordinary sense: it collapses inward, briefly becoming extraordinarily bright before vanishing.

Where does imploding come from?
The word is formed from the prefix in-, meaning “into” or “inward,” together with exploding, from the Latin explodere, literally “to drive out with noise.” Implosion and its related forms developed on the model of explosion by replacing the outward sense with an inward one. English also has the closely related words explode, explosion, and explosive, all sharing the same Latin root.

How imploding is actually used
The physical sense is especially common in astronomy and descriptions of containers, structures, or materials under inward pressure. In figurative use, it often suggests a sudden, severe contraction or collapse, as of a market, organization, or personal situation.
Easily confused with imploding
An object explodes when its contents move forcefully outward, whereas an object implodes when they move or collapse inward.
An imploding star collapses inward under its own gravity, while an exploding star ejects material outward with great energy.
