The very small detected irregularities in the uniformity of the cosmic microwave background are considered to be very important in the study of the evolution of our universe because they:
A) show us that the Big Bang explosion was very nonuniform.
B) were the seeds of supermassive black holes around which the earliest superclusters of galaxies then formed.
C) are thought to have led to the development of the present concentrations of matter and energy in superclusters of galaxies.
D) are thought to contain most of the elusive "missing matter" in the form of energy concentration in the universe.

Quizplus · Accepted Answer

The small irregularities in the cosmic microwave background provided the seeds for the formation of present-day concentrations of matter and energy, particularly superclusters of galaxies. This is because the variations in density led to variations in gravitational attraction, which allowed for the clumping of matter and the eventual formation of galaxies and clusters of galaxies. The irregularities do not directly show us that the Big Bang explosion was nonuniform, nor do they contain most of the missing matter in the universe. While the formation of supermassive black holes may have played a role in galaxy formation, it is not directly tied to the small irregularities in the cosmic microwave background.
