Definition: Acrophony is a term used in astronomy to describe the phenomenon where light from one object can be seen while not being directly illuminated by another object, due to the Earth's shadow. In physics, acrophony refers to the phenomenon of an observer experiencing two images simultaneously and as if they are coming at them from different points. The phenomena is most commonly observed in the night sky, but it may also occur in other environments such as the ocean or on a surface that is not directly visible through the Earth's shadow. In astronomy, acrophony can be caused by a number of factors such as atmospheric distortion or reflection, and it often occurs when light from one object is blocked or blocked by an obstacle. The phenomenon can also occur in conjunction with other phenomena such as the Moon passing overhead. To define 'acrophony', we would need to know more about acrophonics (or "the effect of the Earth's shadow" - not a word used here), which refers to the phenomenon where light from one object is seen, but not directly illuminated by another object. However, without this information, it is impossible for me to provide an accurate definition or understanding of 'acrophony'.
