The James Webb telescope peers through a warped bubble of space-time to study galaxies from the first billion years after the ...

In a new study published in Classical and Quantum Gravity, researchers have revisited the concept of Einstein-Rosen bridges, the theoretical structures often associated with wormholes. This study, ...

Dark energy revived Einstein’s discarded cosmological constant and reshaped the leading model of the universe.

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, fluctuating in brightness for over 17 minutes before fading away. About an hour ...
