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:
“A sense is what has the power of receiving into itself the sensible forms of things without the matter, in the way in which a piece of wax takes on the impress of a signet-ring without the iron or gold.”
—Aristotle (384–322 B.C.)
“The star is the ultimate American verification of Jean Jacques Rousseau’s Emile. His mere existence proves the perfectability of any man or woman. Oh wonderful pliability of human nature, in a society where anyone can become a celebrity! And where any celebrity ... may become a star!”
—Daniel J. Boorstin (b. 1914)
