Textbook Problem

In the past, many scientists believed the universe to be infinite. However, if the universe is infinite, then any Line of sight should eventually fall on a star’s surface and the night sky should be very bright. How is this paradox resolved in modern cosmology?

To determine

To explain:

The paradox as to why the sky doesn't appear very bright due to light emitted from all the stars in our universe.

Explanation

Introduction:

As our universe is expanding continuously, light from stars undergo a process called redshift. Redshift is a phenomenon where the light shifts towards the higher spectrum of red wavelength as the source of light move farther away from us.

If the universe is infinite, then the light from all the stars should reach us and illuminate the entire sky with brightness.

But as the universe is expanding, the stars are moving farther away from Earth...
