3. Classical problems of the Standard Big Bang Model
 

Summary: 3. Classical problems of the
Standard Big Bang Model
and an inflationary solution
I. Aretxaga
2010
· Horizon problem:
­ Why is the CMB so smooth?
· The flatness problem:
­ Why is ~~1 ? Why is the universe flat ?
· The initial fluctuation problem:
­ Where do the very initial fluctuations that seed the
fluctuations we observe in the CMB come from?
· The monopole problem
­ Why aren't there magnetic monopoles, why is there
more matter than antimatter?
The four classical problems of the BB model:
The horizon problem
Why is the CMB so smooth at scales > 2o if these regions were
not causally connected? Why do they have the same T?
(From M. Georganopoulos' lecture lib)
