My paper has quantum theory in mind in relation to relativity, mass and gravity.
In that case, though, physicists will have gained a better understanding of how the predictions of general relativity mesh with Newtonian gravity in the case of galaxies.
Instead of using Newton's theory of gravity to examine why fast-moving stars remain within their galaxies, the pair applied general relativity, Einstein's theory of gravity, to the problem.
Some physicists would rather fiddle with Einstein's theory of relativity, for instance by making gravity weaker at extremely long ranges.
Its fine-scale measurements will even permit scientists to conduct some strenuous tests of General Relativity - Einstein's theory of gravity.
Assuming this principle (without proving it) allowed Einstein to develop the general theory of relativity in 1916, and to describe gravity in purely geometric terms.
FORBES: Physicists Seek A Divorce: Prying Gravity ... From Inertia
Albert Einstein published his theory of general relativity in 1916, offering a description of gravity, space and time that transformed how scientists understand the physical laws governing the known universe.
WSJ: Researchers Spent $750 million��and 52 Years��Affirming Theory of Relativity
"From Einstein's theory of gravity, that is his general relativity theory, we believe mass curves space and this can cause light to follow a curved path, " he told BBC News Online.
One is Einstein's general relativity, which deals with space, time and gravity.
If an object floating through space passes near the line of sight between the earth and a distant star, its gravity should, according to the theory of relativity, bend and focus the light from that star.
Einstein's general theory of relativity states that objects with mass cause a curvature in space-time, which we perceive as gravity.
An anomaly in the orbit of Mercury provided one of the first clues that the laws of gravity as described by Newton were incomplete, which, in turn, led Einstein to general relativity.
