Scientists from Harvard and the University of California in Davis predicted the existence of planetary objects called "synestia," huge, revolving bubble-like masses of hot melted rock that shaped objects the size of the planet as a result of collisions with each other. The study was published in the Journal of Geophysical Research: Planets, produced by the American Geophysical Union.
Moreover, according to researchers, this stage of formation has passed and our Earth. Sinestia occurs as a result of strong collisions of smaller objects with a high speed of rotation, when their substance melts and partially evaporates. With the passage of time, new objects cool and harden, transforming into now almost spherical planets with the accompanying separation of satellites. Sinestia is most like a donut, a bagel or red blood cell. The authors formed this name from the Greek words συν (together) and Eστια (Estia, goddess of architecture). For the study, they used their own program HERCULES (Highly Eccentric Rotating Concentric U (potential) Layers Equilibrium Structure).
