James Webb may have found a galaxy that should not exist because it appeared far too early after the Big Bang. Astronomers believed the first galaxies formed slowly over time. Small galaxies merge together for hundreds of millions of years, but James Webb is discovering massive galaxies in the very early universe. One of the strangest examples is GN-Z11, a galaxy so distant its light began traveling toward Earth over 13 billion years ago. That means we are seeing it shortly after the universe was born. The problem is this, GN-Z11 already appears bright, large, and surprisingly developed. According to older theories, a galaxy like this should not have existed so soon. Now scientists are questioning how quickly stars and galaxies formed after the Big Bang. Some believe the early universe may have evolved far faster than expected. If true, our understanding of cosmic history may need to change completely. So the question is, what else is hiding in the universe's first moments? Follow for more James Webb discoveries.
