👉 In the context of science and technology, "predarkness" is a concept used in astronomy to describe the appearance or appearance of an object after it has been observed from a distance. Predarkness refers to the phenomenon where a star appears brighter than its apparent brightness due to atmospheric refraction. This occurs because as light travels through the atmosphere, it reflects off the surface of the Earth and back towards us. The longer the path taken by the light, the more it is reflected back into space
