Multiple Choice

Suppose the expansion of the whole universe began only about 2 billion years ago, and before that the universe was static and not expanding. What should we expect in such a situation?

• A) We would see redshifts increasing with distance until a distance of approximately 2 billion light years.
• B) We would see a universe that was isotropic but not homogenous.
• C) Distant galaxies would be much smaller than our own, since they have not been expanding for 13 billion years.
• D) The cosmic microwave background would be perfectly uniform in temperature.
• E) We would not expect evidence for a Big Bang.
