In astronomy, an iron star is a hypothetical type of star that could occur in the universe in 101500 years. The premise behind iron stars states that cold fusion occurring via quantum tunnelling would cause the light nuclei in ordinary matter to fuse into iron-56 nuclei. Fission and alpha-particle emission would then make heavy nuclei decay into iron, converting stellar-mass objects to cold spheres of iron. The formation of these stars is only a possibility if the proton does not decay.
Famous quotes containing the words iron and/or star:
“Let us roll all our strength, and all
Our sweetness, up into one ball:
And tear our pleasures with rough strife,
Thorough the iron gates of life.
Thus, though we cannot make our sun
Stand still, yet we will make him run.”
—Andrew Marvell (1621–1678)
“A brush had left a crooked stroke
Of what was either cloud or smoke
From north to south across the blue;
A piercing little star was through.”
—Robert Frost (1874–1963)
