There is no "inside" for an alternative dimension.
neat blue dog
wrong, dimensions are all for inside. we, with our universe are inside spacetime. The possible mother father is not. but there was eternal energy and timespace.
Our universe started at a point in timespace. it is an inside job. at least at that point, the outside realm was infinitely larger, older. still is out there, and we are expanding into it.
