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.

ECONOMIST: Cosmology

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.

ECONOMIST: The dark side of cosmology

From inspiring Newton's theory of gravity to the wassail ceremonies that drive evil spirits from the trees each January, the orchard has long been a place of quiet contemplation and a very British kind of magic.

Physicists would love to develop a way of unifying the forces of nature (electromagnetism, gravity and so on) to produce a Theory of Everything.

ECONOMIST: Particle accelerators

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.

And we might be provided with clues that reveal the trail to unraveling the ultimate holy grail of fundamental particle physics -- a quantum theory of gravity.

CNN: Higgs and the holy grail of physics

With a quantum theory of gravity, we may be able to trace the Big Bang expansion back to its very beginning, and understand precisely how our universe arose, presumably from nothing.

Though Einstein's framework remains intact so far, "the study is significant for the way observations by astronomers are helping to identify new, extreme cases" to test his general theory of gravity, said Dr. Wang.
