In the past, solar eclipses have helped test such things as Albert Einstein's theory of relativity.
This proved a key part of Einstein's theory of relativity for the first time.
In 1905, Albert Einstein's theory of relativity showed that there is no such thing as absolute time.
Some physicists would rather fiddle with Einstein's theory of relativity, for instance by making gravity weaker at extremely long ranges.
The discovery of quantum mechanics and Einstein's theory of relativity, vital to much of modern technology and economic activity, including the transistor, the laser and the atomic bomb.
One example of which the White House is fond is the atomic clock the Pentagon helped Harvard to develop so that scientists could test Einstein's theory of relativity.
Einstein's theory of relativity unified these and created a four-dimensional space that is an analogue to our three-dimensional space, except that the "distance" between two points need not be positive.
In fact, the relativistic offset correction Easton applied to that satellite is still used by every GPS satellite now in orbit, and it also helped to experimentally verify Einstein's theory of relativity for good measure.
ENGADGET: GPS pioneer Roger L. Easton inducted into National Inventors Hall of Fame
The author cannot get through a discussion of Einstein's special theory of relativity without a reference to his own precocity.
This exploits one of the predictions of Einstein's general theory of relativity: that the path of a beam of light (which is a straight line in empty space) is bent inwards by the gravity of a massive object.
ECONOMIST: Cosmology: I spy with my little gravitational lens | The
The SKA will join the hunt for gravitational waves ripples in the structure of space predicted by Albert Einstein's general theory of relativity.
The effect is a direct consequence of Einstein's theory of general relativity which tells us that space is warped by the presence of mass.
BBC: Planck telescope: A map of all the 'stuff' in the cosmos
Although Riemann, who died at the age of only 39, also laid the foundations in geometry for Einstein's general theory of relativity, his paper on prime sattracted little attention in the decades after it was first published.
Einstein's general theory of relativity states that objects with mass cause a curvature in space-time, which we perceive as gravity.
The gravitational field between the two black holes was so strong that it had never been possible to test Albert Einstein's theory of General Relativity in such an extreme situation.
The structure remains the third largest steerable telescope in the world and plays a key role in global research on pulsating stars, testing extreme physics theories including Einstein's general theory of relativity.
One of his great achievements since then, together with mathematician Roger Penrose, has been to prove that Einstein's General Theory of Relativity means space and time has a beginning in the "Big Bang" and ends in black holes.
"Einstein's theory of general relativity tells us that mass bends space and time, so when light comes toward us through the Universe, if it passes some dark matter, its light gets bent and the image we see gets bent and distorted, " Dr Heymans told the meeting.
Its fine-scale measurements will even permit scientists to conduct some strenuous tests of General Relativity - Einstein's theory of gravity.
"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.
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.
Einstein's special relativity theory that says energy equals mass times the speed of light squared underlies "pretty much everything in modern physics, " said John Ellis, a theoretical physicist at CERN who was not involved in the experiment.
It may, as John Learned of the University of Hawaii (another of the team's leaders) suspects, merely show how to extend the current theory in the same way that Einstein's discovery of relativity improved upon, but did not invalidate, Isaac Newton's mechanics.
