Determinations of the motion of the sun with respect to the extra-galactic nebulae have involved a K term of several hundred kilometers which appears to be variable. Explanations of this paradox have been sought in a correlation between apparent radial velocities and distances, but so far the results have not been convincing. The present paper is a re-examination of the question, based on only those nebular distances which are believed to be fairly reliable. Distances of extra-galactic nebulae…

The expansion field: the value of H0
Any calibration of the present value of the Hubble constant (H0) requires recession velocities and distances of galaxies. While the conversion of observed velocities into true recession velocities
Slipher, galaxies, and cosmological velocity fields
By 1917, V.M. Slipher had singlehandedly established a tendency for 'spiral nebulae' to be redshifted (21 out of 25 cases). From a modern perspective, it could seem surprising that the expansion of
The age and size of the Universe
Modern distance determinations to galaxies were reviewed and placed on a uniform and self-consistent scale. Based on eight separate but not entirely independent techniques, the distance to the Virgo
REDSHIFT-INDEPENDENT DISTANCES IN THE NASA/IPAC EXTRAGALACTIC DATABASE: METHODOLOGY, CONTENT, AND USE OF NED-D
Estimates of galaxy distances based on indicators that are independent of cosmological redshift are fundamental to astrophysics. Researchers use them to establish the extragalactic distance scale, to
From magnitudes and redshifts of supernovae, their light-curves, and angular sizes of galaxies to a tenable cosmology
Early physical cosmologies were based on interpretations of the cosmic redshift for which there was insufficient evidence and on theories of gravitation that appear to be falsified by galactic
A NEW METHOD FOR MEASURING EXTRAGALACTIC DISTANCES
We have pioneered a new method for the measurement of extragalactic distances. This method uses the time lag between variations in the short wavelength and long wavelength light from an active
Inspecting the Cepheid Distance Ladder: the Hubble Space Telescope Distance to the SN Ia Host Galaxy NGC 5584
The current tension between the direct and the early-universe measurements of the Hubble constant, H 0, requires detailed scrutiny of all the data and methods used in the studies on both sides of the
The Origins of the Velocity-Distance Relation
Introduction In this paper we shall consider the establishment in the late 1920s and early 1930s of the linear relation between a galaxy's distance and the redshift of its spectral lines: the
A measurement of the Hubble constant from angular diameter distances to two gravitational lenses
TLDR
The angular diameter distance to strong gravitational lenses is used as a suitable calibrator, which is only weakly sensitive to cosmological assumptions, and the Hubble constant is measured to be H0.
Size and age of the universe.
The age of the universe based on abundances of isotopes is in the range 10 billion to 15 billion years. This is consistent with the age range 12 billion to 20 billion years calculated from the
