Multiple Choice
Astrophysicists believe the dominant hot spots in the cosmic background radiation should be about 1° in angular size if the universe is flat.What do experimental measurements of this angular size tell us?
A) The measurements show angular sizes of less than 1°,which suggests that the universe is spherical.
B) The measurements show angular separations of about 1°,which suggests that the universe is flat.
C) The measurements show angular sizes larger than 1°,which suggests that the universe is hyperbolic.
D) The measurements thus far are inconclusive.
