  The discovery of the cosmic microwave background (CMB) in 1964 by Penzias and
Wilson led to the establishment of the hot big-bang cosmological model some ten
years later. Discoveries made in 1998 may ultimately have as profound an effect
on our understanding of the origin and evolution of the Universe. Taken at face
value, they confirm the basic tenets of Inflation + Cold Dark Matter, a bold
and expansive theory that addresses all the fundamental questions left
unanswered by the hot big-bang model and holds that the Universe is flat,
slowly moving elementary particles provide the cosmic infrastructure, and
quantum fluctuations seeded all the structure seen in the Universe today. Just
as it took a decade to establish the hot big-bang model after the discovery of
the CMB, it will likely take another ten years to establish the latest addition
to the standard cosmology and make the answer to ``Cosmology Solved?'',
``YES!'' Whether or not 1998 proves to be a cosmic milestone, the coming
avalanche of high-quality cosmological data promises to make the next twenty
years an extremely exciting period for cosmology.
