A. The cosmic microwave background radiation is expected to contain spectral features due to hydrogen and helium, and it does.
B. The cosmic microwave background radiation is expected to have tiny temperature fluctuations; such fluctuations were found in the COBE data.
C. The cosmic microwave background radiation is expected to have nearly a perfect black body spectrum; observations from the COBE spacecraft verify this prediction.
D. The cosmic microwave background radiation is expected to have a temperature just a few degrees above absolute zero; its actual temperature is about 2.7 K.
E. The cosmic microwave background radiation is expected to look essentially the same in all directions, and it does.
