Recent astronomical observations have revealed the existence of six huge galaxies in the early universe, which challenges the previous understanding of galaxy formation. Joel Leja, an assistant professor of astronomy and astrophysics at Penn State, who analyzed the light emitted by these galaxies, said that these objects are much more massive than what scientists had anticipated.
“This is our first glimpse back this far, so it’s important that we keep an open mind about what we are seeing,” Leja said. “While the data indicates they are likely, 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.
Leja explained that the galaxies the team discovered are so massive that they are in tension with 99% percent of models for cosmology. Accounting for such a high amount of mass would require either altering the models for cosmology or revising the scientific understanding of galaxy formation in the early universe — that galaxies started as small clouds of stars and dust that gradually grew larger over time.
