Explaining what is/was "around" the big-bang was never done properly in most physics courses I've taken, and for a good reason: you need to understand the notion of local space metric before you can get that - as the theory currently stands - there is basically nothing outside of the expanding universe.

There are some things humans will simply never be able to come into contact with or fully comprehend. Such things include the 4th dimension, the concept of infinity, and the concept of nothingness. The universe and what lies outside of it, unfortunately involves all of these concepts, so while there may or not be nothing beyond the universe, because we cannot measure this or engage with this, it is only effectively nothing and not literally nothing.
