The accelerating expansion of the Universe, first observed in 1998, remains one of the most profound mysteries in modern physics. It challenges long-standing assumptions about the cosmos and has ...

Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

To square Albert Einstein’s General Theory of Relativity with quantum mechanics requires some currently unknown physics, and that’s led some scientists to question if Einstein’s theory could use some ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

A theoretical proposal published in the journal Reports on Progress in Physics is making some bold claims about our previous understanding of quantum physics. Mainly, that we were wrong. The proposed ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

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.
