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

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

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

Black holes themselves emit no light, but the matter spiralling into them forms a hot, dense accretion disc that radiates ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Recent discoveries show that runaway black holes, moving at extraordinary speeds, are tearing through galaxies, leaving ...

New simulations show flickering black hole signals arise from unstable shocks inside accretion discs, revealing how matter ...

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...
