We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

COLUMBIA, Mo. – Scientists have attempted to disprove Albert Einstein’s theory of general relativity for the better part of a century. After testing and confirming Einstein’s prediction in 2002 that ...

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

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...
