The JWST findings could reshape what was thought to be settled science.
on board that can detect light that was emitted by the most ancient stars and galaxies, allowing astronomers to see roughly 13.5 billion years back in time.
“This is our first glimpse back this far, so it’s important that we keep an open mind about what we are seeing,”. “While the data indicates they are likely galaxies, I think there is a real possibility that a few of these objects turn out to be obscured supermassive black holes. Regardless, the amount of mass we discovered means that the known mass in stars at this period of our universe is up to 100 times greater than we had previously thought.
Since these six galaxies were far more massive than anyone on the team expected them to be, they could upend“The revelation that massive galaxy formation began extremely early in the history of the universe upends what many of us had thought was settled science,”. “We’ve been informally calling these objects ‘universe breakers’ — and they have been living up to their name so far.”
The authors argue that the “universe breakers” are so large, that almost all modern cosmological models fail to explain how these star systems could have formed.“We looked into the very early universe for the first time and had no idea what we were going to find,” . “It turns out we found something so unexpected it actually creates problems for science. It calls the whole picture of early galaxy formation into question.”that could provide data on the true distances between us and the mysterious galaxies, as well as the gasses and other elements present. It would also paint a more clear picture of what these galaxies looked like billions of years ago.. “It will show us how big they are, how far away they are.
