In some moment lost in time, the Sun could not have been this silent and lifeless sphere. Some scientists believe that it already had intense geological activity. Tremors. Internal heat. Maybe...something more. The lunar surface bears marks that do not correspond to the calmness we see today. Mysterious trails. Giant grooves
