Scientific paper

Some of the current hypotheses for the origin of structure in the universe are described along with calculations which have been made to predict the amplitude of the microwave anisotropy. The dipole anisotropy of the microwave background is described as extrinsic, and a solar motion is inferred which can be used to constrain both the large-scale density fluctuations in which the observer is embedded and independent determinations of the observer's motion relative to distant galaxies. It is concluded that observation and theory are coming very close to measuring the elusive anisotropy or to revealing that present ideas about the origin of galaxies and large-scale structures are in need of substantial revision.
