A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

Imagination has never been the most intractable problem in the physics of warp drive; it has been bookkeeping. The Alcubierre concept of 1994, the celebrated one, fits in the general relativity theory ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

Proposals offering alternatives to Einstein’s relativistic theory of gravitation are almost as old as the theory itself. Einstein even saw them as the beginning of a path that could lead to quantum ...

A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

A millimeter might not seem like much. But even a distance that small can alter the flow of time. “This is fantastic,” says theoretical physicist Marianna Safronova of the University of Delaware in ...
