cosmology - Creation of a miniature universe?



I am not referring to the experiment being conducted at Lancaster University involving liquid helium and a magnetic field to build a marble sized representation of the early cosmos.


My question is: would it theoretically be possible to actually construct a brane which would exist inside a bulk of our own design? Something observable? A tiny universe which would be born from a baby bang and develop in a similar way to our own universe as we have observed it.


If such a thing were possible:



  • What would the time scale be?

  • Would it be perceived by the observers (us) as accelerated or perhaps slow?

  • Would the universe be lost forever after creation, unable to be observed?


I also understand that at a quantum level, matter actually behaves differently depending if it is being observed or not observed by an entity affecting it's state... even to the point where a temporal change can take place, would this also have an effect on observing a tiny universe?
