The reason behind people thinking there was blackness between the stars.
![Check Mark](/static/check-mark.png)
Answer to Problem 1RQ
The reason behind people thinking there was blackness between the stars is because stars are distant from each other, and the space between them is empty and dark.
Explanation of Solution
Looking at the sky at night, a person can observe the black sky with plenty of stars. Before the early 20th century, people concluded that the universe consisted of millions of stars with a vast area of emptiness. The sky consists of billions of stars, and together they are called a galaxy.
According to the researcher, there are several numbers of galaxies in the universe. The space between the stars or galaxies is almost empty, which may range from a few light-years. This empty space between the stars, when observed from the Earth, seems to be black and dark. This is the reason people assume that there was complete blackness between the stars.
Conclusion:
Therefore, the reason behind people thinking there was blackness between the stars is because stars are distant from each other, and the space between them is empty and dark.
