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

  1. Oct 8, 2014 #1
    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?
