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 2
The currently accepted reasoning for why the cosmic background radiation is so uniform in temperature is because
A) this temperature uniformity was achieved in the moments before cosmic inflation.
B) as the universe has had time to cool, the hotter parts transferred their heat to the cooler regions.
C) microwaves can only function at a certain very limited range of temperature.
D) space is a vacuum and thus cannot retain heat very well.
