James Webb Telescope discovers an isolated massive black hole in the early universe challenging galaxy formation theories.
The James Webb Space Telescope has discovered a massive black hole weighing 50 million times the sun’s mass, existing alone without a surrounding galaxy just 750 million years after the Big Bang. This challenges existing theories that black holes form only after galaxies and stars develop.
Why it matters: This finding contradicts the traditional model where galaxies form before black holes, suggesting black holes might arise independently or even before galaxies.
The big picture: Hundreds of similar "little red dots" hint at a chaotic early universe where black holes and galaxies formed simultaneously or independently.
The stakes: Understanding these "naked" black holes could rewrite cosmic history and impact theories about the universe’s formation and evolution.
Commenters say: Many highlight JWST’s revolutionary role, debate possible origins like primordial black holes or direct gas collapse, and appreciate the reminder that science constantly evolves with new data.
