The reason behind people thinking there was blackness between the stars.
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.

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion?
