If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

As companies explore AI technologies they can deploy right away, Retrieval Augmentation (RAGs) are emerging as a quick and easy win.

Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with ...

Astronomers have identified an enormous "growth spurt" in a so-called rogue planet. Unlike the planets in our solar system, these objects do not orbit stars, free-floating on their own instead. The ...

A gravitational singularity refers to a point in spacetime where density and curvature become infinite, and the equations of general relativity no longer provide meaningful predictions. Theoretically, ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...

Alexander Grothendieck was a titan in his field, making deep connections that fuelled a revolution in mathematics, before giving it all up and disappearing. Jacob Aron explores what his work meant ...
