Astronomers tried and failed to find a flaw in the famous physicist’s theory of gravity

Chalk up another win for Einstein’s seemingly invincible theory of gravity. A new study shows that the theory of general relativity holds true even over vast distances.
General relativity prevailed within a region spanning a galactic distance of about 6,500 light-years, scientists report in the June 22 Science. Previously, researchers have precisely tested the theory by studying its effects on the solar system (SN Online: 8/15/17). But experiments on larger scales are more difficult. The new test is the most precise one yet across such great distances.
According to general relativity, the force of gravity is the result of matter warping spacetime (SN: 10/17/15, p. 16)
