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:
“Should the German people lay down their arms, the Soviets ... would occupy all eastern and south-eastern Europe together with the greater part of the Reich. Over all this territory, which with the Soviet Union included, would be of enormous extent, an iron curtain would at once descend.”
—Joseph Goebbels (1897–1945)
“I have drunk ale from the Country of the Young
And weep because I know all things now:
I have been a hazel-tree, and they hung
The Pilot Star and the Crooked Plough
Among my leaves in times out of mind....”
—William Butler Yeats (1865–1939)
