The discussion centers around the hypothetical implications for cosmology if a galaxy older than 13.8 billion years were discovered. Participants explore the theoretical and conceptual ramifications of such a finding, including its potential impact on current cosmological models and understandings of the universe's age.
The discussion reflects a lack of consensus, with participants presenting varied perspectives on the significance of the hypothetical discovery and its implications for cosmology. Some focus on the scientific process that would follow such a finding, while others critique the framing of the question itself.
Participants do not fully explore the scientific mechanisms that would be involved in redefining cosmological models, nor do they address the assumptions underlying the current understanding of the universe's age.

"They" would write a paper about it, and get the paper published in a peer-reviewed journal. At that point you would start a new thread with a link to that paper to start a discussion about it. I'll wait...Jupiter60 said:Summary: What would happen if they found a galaxy that was older than 13.8 billion years old?
What would happen if they found a galaxy that dated to older than 13.8 billion years old? How would this affect cosmology?
