Is there an unseen part of the universe older than the known universe?

The best theories have the universe arising from a singularity 13.8 billion years ago, and have it expanding, becoming increasingly dilute and frigid for eternity. Do you think the Copernican principle holds for the universe and that we inhabit a small part of a vaster cosmos permanently beyond the cosmic horizon? Our observable universe had a beginning, but do you think what if anything lies beyond the horizon is older?

I suggest you start by reading this thread https://www.physicsforums.com/threads/effort-to-get-us-all-on-the-same-page-balloon-analogy.261161/

After you read that thread, if you still have questions, you can start a new thread with more focused questions in the cosmology forum.

Are you asking for peoples' opinions, or for the mainstream view of what's beyond the observable universe?

I cannot definitively answer whether there is an unseen part of the universe that is older than the known universe. However, based on our current understanding of the universe and its origins, it is unlikely that there is an older part of the universe beyond our cosmic horizon.

The best theories of the universe, such as the Big Bang theory, suggest that the universe began as a singularity approximately 13.8 billion years ago. This event marked the beginning of time and space as we know it. Since then, the universe has been expanding and becoming increasingly dilute and frigid. This expansion is expected to continue for eternity.

The Copernican principle, which states that we do not occupy a special or privileged position in the universe, holds true for the observable universe. However, beyond our cosmic horizon, we cannot make any definitive statements about the nature of the universe. It is possible that there are other regions of the universe that have different properties or ages, but we currently have no way of observing or studying them.

In conclusion, while it is possible that there is an unseen part of the universe that is older than the known universe, there is currently no evidence to support this idea. Our observable universe had a beginning, and it is likely that what lies beyond our cosmic horizon is also a part of this same timeline. Further research and advancements in technology may provide more insight into the nature of the universe and its origins.
