The Multiverse

The concept of the multiverse extends to the possibility of an infinite number of universes constantly popping into an out of existence. Some of them have laws of physics allowing them to survive for various lengths of time and others disappear almost instantly because of instabilities.  

Is there a possibility that we are a universe, inside of a universe, inside of a universe, etc? Definitely. It is also possible that there is a larger something that provides structure or direction to it all.  

Our understanding is definitely limited by the abilities of our senses, our manufactured sensors, and the limits of our abstract thought. We only perceive and process a portion of what is around us. For our senses much of the electromagnetic spectrum is beyond our ability to detect. For our manufactured sensors whatever constitutes dark energy and dark matter is beyond our capabilities for example. We are able to infer that dark energy and dark matter exist by the influence they have on what we can detect. It is possible there is infinitely more out there that our senses and sensors cannot and potentially never will be able to detect. For instance if there are other universes, realities, objects, etc. that are governed by laws of physics not congruent with our own known universe’s laws, then left to our own devices we will remain forever unenlightened about these other entities. There may be many other things around us, inside of us, or outside of our universe that are either older or younger than our 13.5 billion year universe.
