Amazing Scientific facts about life on the sun and stars
In 1979 the scientist and the nanotechnologist Robert Freytas Jr. assumed possible, not biological life. He declared that possible metabolism of live systems is based on four fundamental forces — electromagnetism, strong nuclear interaction (or quantum chromodynamics), weak nuclear interaction and gravitation. Electromagnetic life is a standard biological life that we have on Earth. Chromodynamic life could be based on strong nuclear interaction which is considered the strongest of fundamental forces but only at extremely short distances. Freitas assumed that such an environment can be possible on a neutron star, the heavy rotating object of 10-20 kilometers in the diameter with a mass of a star. With an improbable density, the most powerful magnetic field and gravitation in 100 billion times are stronger, than on Earth, such star would have a kernel with a 3-kilometer crust of crystal iron. Under it, there would be a sea with incredibly hot neutrons, various nuclear particles, protons, and atomic nuclei and possible “microkernels” rich with neutrons. These microkernels in the theory could create large sverkhjyadr, similar to organic molecules, neutrons would act as a water equivalent in the fancy pseudo-biological system. Freitas saw life forms based on weak nuclear interaction as improbable as weak forces work only in the subnuclear range and aren’t especially strong. As often shows beta radioactive decay and free disintegration of neutrons, life forms of weak interaction could exist in case of careful control of weak interactions in the environment. Freitas provided the beings consisting of atoms with excessive neutrons which become radioactive when die. He also assumed that there are regions of the Universe where weak nuclear force is stronger, and, so chances of emergence of such life are higher. Gravitational beings can exist too as gravitation is the most widespread and effective fundamental force in the Universe. Such beings could receive energy from the gravitation, receiving unrestricted food from collisions of black holes, galaxies, other heavenly objects; it is less being — from the rotation of planets; the smallest — from the energy of falls, wind, inflows and oceanic currents, perhaps, earthquakes.
