[00:00:00]James Webb just broke cosmology. It found a galaxy from when the universe was only 300 million years old. The universe is 13.8 billion years old. This galaxy >> [music] >> formed at 2% of that. Galaxies aren't supposed to form that fast. It takes hundreds of millions of years for gas to collapse into stars, for stars to become galaxies.

[00:00:26]This galaxy [music] skipped all of that.

[00:00:28]Already massive, already ancient, before the universe was even an infant.

[00:00:34]Scientists called it impossible, then found another, then another.

[00:00:41]Dozens of galaxies that shouldn't exist this early.

[00:00:44]Either our understanding of how galaxies form is completely wrong, or something [music] was accelerating the early universe in ways nobody predicted. 60 years of cosmology, Webb just cracked it.
