	Yes. This is possible. It requires that the universe be 
continuous with laws that apply irrespective of scale. Einstein 
was not too far off the track, according to many current 
theories, is stating that the universe was finite and unbounded, 
and spherical in shape. The current theories indicate that the
universe is curved, ( the known universe, that is ) but is not 
curved enough to completely curve in on itself. The comparison 
between the known universe and black holes are compelling. It
is possible that black holes are actually smaller universes that 
are exploding, but virtually unobservable because of the time 
dilation effect. This introduces the idea of a force opposing 
gravity that, because of time dilation, causes the universe to be 
an unstable oscillator in certain regions, regardless of scale.

	In other words, the curvature of space in the known 
universe is simply a localized region in the grander scheme of 
things.
