Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

Humanity has achieved remarkable feats, yet 95% of the universe remains invisible and unexplained. Our theories, general ...

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

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, ...

Question: I read a brief history of time by hawking and I am interested to know why Einstein’s theory of relativity and quantum physics can’t come together to come up with a theory of everything?” ...

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 ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

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 ...

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

In physics, Albert Einstein is famous for two things: developing the theory of relativity, and hating quantum mechanics. Relativity is a colossal achievement, with the special theory of 1905 putting ...
