The James Webb Space Telescope has discovered galaxies forming just 300 million years after the Big Bang that are too large, bright, and organized to exist that early, including one galaxy (JADES-GS-z14-0) that formed when the universe was only 2% of its current age and producing stars at rates exceeding our Milky Way, as well as supermassive black holes billions of times the sun's mass when the universe was less than a billion years old, forcing scientists to reconsider fundamental models of galaxy formation and the early universe.

JWST Just Found Galaxies That Shouldn't Exist — You Won't Believe This #shortsAjouté :
The James Webb Space Telescope just broke cosmology.
Again.
It found galaxies forming just 300 million years after the Big Bang.
Galaxies that are too big, too bright, and too organized to exist that early in the universe.
According to our models, the early universe should have been a chaotic mess of hydrogen gas and dark matter.
Stars hadn't had time to form. Galaxies shouldn't exist yet. But JWST keeps finding them.
One galaxy called Jade's GS-z14-0 formed just 290 million years after the Big Bang.
That's when the universe was only 2% of its current age. And it's already producing stars at a rate that makes our Milky Way look lazy.
Another discovery, galaxies with supermassive black holes at their centers. Black holes billions of times the mass of the sun when the universe was less than a billion years old.
How did they grow so fast? We genuinely don't know.
Scientists are now considering three possibilities.
One, our models of galaxy formation are wrong.
Two, black holes form directly from collapsing gas clouds, skipping the star phase entirely.
Three, our understanding of the early universe is fundamentally flawed. JWST hasn't just found new galaxies, it's found a crisis in physics. And that's exactly what great telescopes are supposed to do.
