When the energy you need to access these areas are orders of magnitude larger that what we have on earth (except for pinpointed single places such as the LHC) then it does not make sense. You simply cannot make use of them. Let's get back to them when we have the energy. This is similar to astrophysics where you discover that a sun has planets. And do what. Are you going to go there anytime? Or use it to modify your own planet? You won't, and any dreaming won't change that.
