Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Scientists say fragments of energy may be the fundamental building blocks of the universe—not particles and waves.

We can design tests to check if the universe obeys the rules of Einstein’s theory. General relativity describes gravity as the curving or warping of space and time, bending the pathways along which ...

According to Albert Einstein's theory, the Universe is deformed by matter, like a large, flexible sheet. These deformations, caused by the gravity of celestial bodies, are called ''gravitational ...

The pair put their new theory to the test by evaluating two prominent astronomical observations that were used to confirm Einstein's theory of general relativity. The first was Mercury's unusual ...

Infinite Beginnings Pushing the limits of theory and imagination in true Einsteinian fashion, cosmologists are daring to speculate that ours is not the only universe. The big bang that created ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.
