The simple Big Bang theory does not solve all of the problems that we observe (or hope to observe) in our universe. These problems include all of the following EXCEPT:

a. the existence of magnetic monopoles.
b. the explanation for the observed flatness of our universe.
c. the explanation of the extreme homogeneity of direction of our universe.
d. the explanation of why our universe appears to be expanding at an accelerating rate.
e. the explanation of why the universe was so hot at the beginning and has cooled off.


e.
The Big Bang does explain that the universe used to be very dense and therefore very hot. The expansion of the universe explains the cooling
