Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

What are the little red dots discovered by the James Webb Space Telescope? These X-rays may offer a clue.

"The dark structures shaping galaxies today could be relics from a time before the Big Bang." The post Physicist Proposes ...

Black holes are usually framed as the ultimate dead ends of the universe, but a new mathematical proposal suggests they might instead be raw material for building shortcuts through spacetime. In this ...
