Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond.

We know that Einstein’s general relativity is, strictly speaking, wrong. That’s because it doesn’t account for quantum effects despite the fact that those e ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

Friedmann accepted this new term but pointed out a radical alternative: the universe did not have to be frozen. He argued that Einstein’s static universe was merely a special case and that the cosmos ...

Time is a straightforward concept - or is it? The passing of minutes and years isn't as easy to explain as many assume.

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...

Vladimir Fock occupies a distinctive place in the history of twentieth-century science, not only for his profound ...

Since decades quantum gravity tries to close the gap to general relativity, but all attempts remain pure theory without empirical test. The present study now extends loop quantum gravity to a verified ...
