flux capacitor

DeLorean's temporal core

A flux capacitor is the fictional device that enables time travel in the *Back to the Future* film series.

Doc Brown's DeLorean requires the flux capacitor—along with 1.21 gigawatts of power—to break the time barrier.

The term has become a joking reference to any mysterious or nonexistent component: The mechanic said my car needs a new flux capacitor.
