Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

Technologies for energy storage as well as biological systems such as the network of neurons in the brain depend on driven ...

On 2 July, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose brightness varied rapidly during a routine sky survey. Its unusual signal ...

For more than a century, a single metal cylinder in a Paris vault quietly defined what a kilogram was. After 130 years, ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

The atmospheric scientist Eric A. Kort has accepted the appointment as new director of the Atmospheric Chemistry Department at the Max Planck Institute for Chemistry in Mainz.

Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...

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, ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...
