Astrophysical Observations: Lensing and Eclipsing Einstein's Theories

I found the following that might be of general interest, particularly
given the large number of alternative gravity hypotheses posted here,
often by people who I fear do not understand GR.

Title: Astrophysical Observations: Lensing and Eclipsing Einstein's Theories
Authors: Charles L. Bennett
Journal-ref: Science, vol. 307, pages 879 - 884 (11 February 2005)

Albert Einstein postulated the equivalence of energy and mass,
developed the theory of special relativity, explained the
photoelectric effect, and described Brownian motion in five papers,
all published in 1905, 100 years ago. With these papers, Einstein
provided the framework for understanding modern astrophysical
phenomena. Conversely, astrophysical observations provide one of the
most effective means for testing Einstein's theories. Here, I review
astrophysical advances precipitated by Einstein's insights, including
gravitational redshifts, gravitational lensing, gravitational waves,
the Lense-Thirring effect, and modern cosmology. A complete
understanding of cosmology, from the earliest moments to the ultimate
fate of the universe, will require developments in physics beyond
Einstein, to a unified theory of gravity and quantum physics.
