Traveling universe ?
Traveling outside the universe seems like scientific movies ..... but what if we made a thing by which we can travel the universe .....
if we go outside the universe, we are moving mass there, so the universe will expand, it means, we will never be outside the bubble. By other side, if we are able to go outside the bubble without expanding it, our mass cease to exist, so we instantly disappear.
What is beyond the universe ?

How long will universe last ?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
where does universe end ?
NO, they don't believe there is end to the universe ... we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
What was before the universe ?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and space time of the Universe.
