The "flatness" problem arises because the curvature of space seems remarkably close to:
A)zero curvature, favoring a spherical cosmos.
B)exactly one.
C).5, suggesting we are split between open and closed universes.
D)2.73 K, in spite of the eddies and turbulence that led to galaxy formation.
E)infinity, suggesting an open universe is the only possible cosmology.

The flatness problem arises from the fact that the curvature of space appears to be extremely close to exactly one. This is problematic because if the curvature were even slightly different, the universe would either rapidly expand or collapse, making our existence and observation of the universe unlikely. The fact that the curvature is so close to one suggests a need for an explanation, such as inflation during the early universe.
