A Question of Physics ... On the subject of astrophysics in the Three Galaxies at large I will attempt to explain the relationships between those zones known as: real space, sub-space, hyper space and flux space. Please remember, these realms are, now, fictional and at best might be the subjects of current scientific theory. ...
