What is Outside the Universe ?

The Universe is made up of 4.6% atoms,24%dark matter and 71.4% dark energy and consists of billions of galaxies and billions of stars and planets but as per the astronomers the universe is interconnected by a cosmic web and only  4% can be seen out of it whereas 96%  astronomers can't see nor detect but what lies beyond the universe as we don't know weather the Universe is infinite or not but I thinks that Something is beyond the Universe and the Universe is Finite maybe it has a limit  that it has not reached yet and is reaching towards that limit and may be there are too many Universes and may be there is something outside the Universe maybe a Heaven.Yes,there can be a heaven outside the Universe  I am not saying that there would be God living there but something like an heaven or we can get to see other universes there and maybe some humans with advance machine or may be our creators if they are there.
