Exploring the Interplay between Human Perception, Astrophysics, and the Nile River: Unravelling the Significance of Sirius

Abstract

The Sirius star holds a significant historical significance and has captivated numerous civilization and individuals throughout time. Understanding the human perception and physics of Sirius can provide insights into the evolution of astronomy and its impact on the flora and fauna. Prehistoric astronomers believed that the appearance of Sirius in the sky was a signal for the Nile River to flood, and many cultures have depicted the star in their art and literature. Despite its significance, there is a lack of research on the connection between Sirius and the Nile River, and the impact of human perception on the study of astronomy. The aim of this study is to investigate the interactions between human cognition, astrophysics of Sirius, and the Nile River. Therefore, measurements of the wavelength, temperature, and brightness of stars as well as human impressions of their colors and patterns can influence physics (science). The results showed that 68 (45.33%) disagreed with the connection between the filling of the Nile River and the calendar and 82 (54.67%) believed that the Ethiopian calendar had a connection with the filling of the Nile River. Therefore, the majority of respondents agreed that 146 (97.33%) out of 150 respondents knew that the appearance of the star in the Northern Hemisphere is a signal that winter is coming. The mass of the star Sirius is about twice that of our Sun, while its diameter is about 1.7 times larger. Additionally, through image editing method, we improve star images by reducing noise. The results of this study will show that human perception and physics have played a significant role in shaping our understanding of Sirius and its impact on the world's flora and fauna.
