How is it possible that today's diverse universe was able to arise from that which was very homogeneous at its first moments?
A)Inflation magnified ultrasmall quantum variations in position and momenta.
B)There is evidence of a second,slightly smaller Big Bang that took place very shortly after the initial Big Bang,which would account for the variation in structure.
C)The rapidly cooling universe created massive quantities of hydrogen,and then helium,which interacted with each other to create regions of relative structure.
D)Entropy immediately came into effect,slowing down some areas of expansion,while increasing others.

Question

Quizplus · Accepted Answer

The theory of cosmic inflation proposes that in the early moments of the universe, a rapid expansion occurred, during which quantum fluctuations were amplified, leading to the generation of density variations that became the seeds of galaxies and large-scale structure.

Answer: C
 As the universe expanded and cooled, the first atoms formed – mostly hydrogen and helium – and gravitational forces pulled matter closer together in some regions, creating regions of higher density that eventually led to the formation of galaxies and clusters of galaxies.

Therefore, the best choices are A and C.
