Iron star

In astronomy , an iron star is a hypothetical, compact star that could appear in the universe in the extremely distant future after about 10 ¹⁵⁰⁰ years .

Due to cold fusion through the tunneling effect of quanta, all light nuclei of normal matter become iron -56 nuclei after extremely long periods of time . Nuclear fusion and alpha particle emission will then break down any heavier particles into iron. As a result, even objects of stellar mass become cold spheres of iron.

However, the formation of such stars will only take place provided that there is no proton decay .

Although the surfaces of neutron stars are made of iron, they are not iron stars .

When the steady-state theory was still prevalent in astrophysics, it was assumed that the Milky Way would also contain iron stars.
