Answer:
Robert Lawrence Kuhn is the creator, writer and host of "Closer to Truth," a public television series and online resource that features the world's leading thinkers exploring humanity's deepest questions. Kuhn is co-editor, with John Leslie, of "The Mystery of Existence: Why Is There Anything at All?" (Wiley-Blackwell, 2013). This article is based on a "Closer to Truth" episode produced and directed by Peter Getzels and streamed at www.closertotruth.com. Kuhn contributed this article to Space.com's Expert Voices: Op-Ed & Insights.
Since childhood, I've obsessed about existence. What is existence? What's the extent of existence? What's the purpose of existence? Now, six decades on, having explored many things, I'm no surer (and feeling no smarter), but I continue my pursuit.
What's the largest, surest fact about existence that I can know with confidence? For me, it's the vastness of the cosmos. The universe is huge, but it is only with recent discoveries that we can realize how inconceivably immense the universe, or multiple universes, may actually be.
It's now one of humanity's ultimate questions — and until relatively recently, we didn't know enough to even ask it. How many universes exist?
The multiverse
If we define "universe" as "all there is" or "all that exists," then obviously, by definition, there can be only one universe.
But if we define "universe" as "all we can ever see" (no matter how large our telescopes) or "space-time regions that expand together," then many universes may indeed exist. There is nothing in science more awesome, more majestic. To discern the nature of ultimate reality, one must begin with the challenge of multiple universes.
So what is a "multiverse"?
As physicist and Nobel laureate Steven Weinberg told me on "Closer to Truth" (the source of all following interviews), "The word 'universe,' I suppose, should properly mean the whole thing — everything. But when we think of 'universe,' we sometimes use the word to mean just our Big Bang, the things we can see out to almost 14 billion light-years in all directions. And in this manner, it's reasonable to question: Is our universe unique? Are there multiple Big Bangs? Could there be multiple Big Bangs in different senses
Thirteen point eight billion years ago, we started the hot Big Bang of what we know as our Galaxy. Since, through and including today, it has been growing and cooling. From our viewpoint, the light speed & space extension allow us to look back some 46 billion light years in all directions. While the gap is immense, it's not infinitely large.
Explanation:
- First of all, the universe is finite yet possible. Everything that we know for sure (most of it for sure) is that it is larger than we can observe, primarily because we have no edge at the farthest limits of the universe. Although the universe is still immense, it still has boundaries. It is because we know that the universe is not infinitely old — we know that 13,8 billion years before the Big Bang happened..
- But the light had to fly for "just" 13.8 billion years. That was a good amount of time, however the universe is large enough for scientists to be pretty confident that there is space beyond our detectable bubble and also that the universe is simply not old enough to reach us.
