If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Researchers have adapted Bell’s theorem from quantum mechanics to help them predict financial crises before they happen.

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

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 ...

Testing Einstein: conceptual image showing S0-2 (the blue and green object) as it made its closest approach to the supermassive black hole at the centre of the Milky Way. The huge gravitational field ...

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 ...

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 ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

THE preoccupation of philosophers with relativity, to the exclusion of all other branches of science, is very puzzling to a physicist; but most puzzling of all is their continual assertion that ...
