Research institutes have been testing Albert Einstein's theory of special relativity and general relativity.

Eclipses in a unique system of two dead stars, called pulsars, has shown that one of the pair is 'wobbling' in space - just like a spinning top. The effect, called precession, is precisely as predicted by Albert Einstein and is thus a new and exciting confirmation of his theory.

This discovery supports the implication of Einstein's relativity theory that black holes of all sizes have similar properties, and will be useful for predicting the properties of a conjectured new class of black holes.

An new analysis has shown that no more than 4 percent of the energy loss of the pulsar is caused by the emission of gravitational waves.

The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics. But this requires much more interaction between astronomical theory and observation, and in particular the development of a new breed of astronomer who understands both.

The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking.

Researchers say: "This extra dimension would be curled up, in a state similar to that of the entire universe at the time of the Big Bang."

The deformation prediction instrument uses the technology of optical interferometry to make precise measurements that identify weak spots in a wide range of materials, including metals, plastics and other products.

After testing and confirming Einstein's prediction in 2002 that gravity moves at the speed of light, a professor has spent the past five years defending the result, as well as his own innovative techniques for measuring the speed of propagation of the tiny ripples of space-time known as gravitational waves.

The main question is: if, according to the principles of curvature development in the theory of relativity, can a time machine be created? In other words, can we cause space-time to curve in such a way as to enable travel back in time? Such a journey requires a significant curvature of space-time, in a very special form.

String theory emerged 40 years ago as one of the most promising candidates for such a theory, and has since slipped in and out of favour as new innovations have occurred. Now Europe is fortunate to have one of the world's leading experts in string theory working on an ambitious project that could make significant progress towards a unified theory, and at least help resolve two mysteries. One is how the universe emerged in the beginning as a random fluctuation of a vacuum state, and the other is a common explanation for all sub-atomic particles.

A physicist recently argued in a paper that the interpretation of the results of Lunar Laser Ranging, which is being used to detect the gravitomagnetic field, is incorrect because LLR is not currently sensitive to gravitomagnetism and not effective in measuring it.

UC Berkeley's Dean Toste attributes these properties to relativistic effects in the gold atom, the same effects that give gold its yellow luster.

The comparisons at NIST may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.

This inflationary phase, after only a trillionth of a second, concluded with a violent conversion of energy into hot matter and radiation. This "reheating" process also resulted in a flood of gravitational waves.

Now, researchers at Carnegie Mellon University; the University of California, San Diego; and The University of Texas at Austin have developed a test of string theory. Their test, described in the January 26 Physical Review Letters, involves measurements of how elusive high-energy particles scatter during particle collisions.

The new data shows that vacuum energy is the most likely cause and the expansion history of the universe can be explained by simply adding this constant background of acceleration into the normal theory of gravity.

No one has observed such a phenomenon so far, but University of Washington researchers believe it is possible to detect such waves coming from strange wispy structures called cosmic superstrings.

Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate.

The team used supercomputers to perform the most precise energy calculations ever made for these atoms and their properties. As a result, astronomers -- in particular, those hunting black holes -- will have a better idea of what they are looking at when they examine faraway space matter using X-ray telescopes.
