We're taught about powers of ten and how space is endless and vast. There are stars and clusters of stars, galaxies and clusters of galaxies that make up the entire universe. But one question I always ask and I have never heard anyone else talk about it... what if a picture larger than our universe revealed that there are other big bangs. What if we zoom far enough out to where each pinpoint of light we see is actually an expanding universe. Of course we could never know about these other universe's because the light would not have reached us yet. Just food for thought... I've never brought it up with anyone before.
