Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

This stunning image reveals a distant galaxy cluster teeming with energy: galaxies shine in visible light (white), ghostly red clouds unveil a newly discovered radio mini-halo—the most distant ever ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

Using gold flakes, salt water, and light, scientists have made the universe’s invisible binding forces visible in color. The discovery opens new possibilities for studying how matter organizes itself ...
