After this point, it would collapse into something like a sputtering white dwarf or neutron star, and thenif its mass kept increasingeventually become a black hole.

Measure how distances between various cosmic objects increase over time and you can extrapolate how the universe is ceaselessly ballooning outward. Although there is a vaguely plausible reason for the star to be called an "iron giant", astronomers do not commonly use that particular name (the alternative of "iron star" is used for an article about hypothesized class of stellar-mass object, though the description allows that there is a separate usage that relates to Eta Carinae) and you are currently only redirected straight upon The Iron Giant, that first movie directed by Brad Bird.
