I know some questions might never get an answer but our ever curious minds can't help think about them;
- what lies beyond our observable universe (hubble volume)?
- what is the nature of the boundary of the entire universe (both observable and un observable) and what lies beyond it?
- is our universe the only universe we have or we have other infinite universes beyond ours, if yes then what separates them (the nature of that space between these universes)?
