Endless space. That is the container.
People all think of our 'universe' as the ultimate container for everything we know and could comprehend.
Some
 have suggested the idea of other universes in a sort of 'multiverse', 
however there is no multiverse, nor is our universe anything in itself 
but a spread of matter from a central point (singularity/ 'big bang'). 
Endless spreads of matters such as our own in all likeliness exist 
throughout space.
Space doesn't have borders or limits to 
its expanse and size, because it is not a measurable object spanning a 
distance or a container, it simply 'is', it's nothingness and the 
container for all that isn't nothingness as well as its own infinite 
vacuum.
Don't define space as our universe, for our 
universe is within space, and that definition limits the minds eye on 
the subject. Just as there are solar systems, galaxies, galactic 
clusters, everywhere in our existence at the smallest and largest levels
 we know, we see consolidations of matter at points, all part of a 
larger thing - from the atoms spaced apart in what we see as solid 
objects such as our own body or a plank of wood, to the very planets and
 galaxies. To universes, probably spread endlessly throughout infinite 
space.
What are your thoughts on the origin of the 
singularities ('big bang points') from which universes originate? Were 
they perhaps themselves a universe once, that over endless billions of 
years of gravitational pull of its own galaxies together once again 
reached a sort of 'singularity mass'?
