Hi Dippy

They are not 'directions' as the diagram is not representative of our three dimensional universe. It maybe that the 'direction' illustrated is a fourth spatial dimension? The drawing appart is separated by the singularity in which no matter exists so there is no intermingling.

The anthropomorphic principle (or whatever it is) postulates that, since we exist, something must have happened to allow real matter to form. Current thinking supposes that matter and antimatter were created in our universe in equal quantities but the antimatter has been destroyed leaving a (small) residue of matter for us to exist in and observe. My alternative postulates that matter and antimatter draw appart across a boundary (no I can't define it) which results in two parallel worlds. Any small residues of the wrong stuff will be anihilated immediately in contact with the right stuff.

I think that this is a likely scenario for the creation of each galaxy and the principle is similar to Lee Smolin's fish egg theory which has many such events taking place for us to experience a viable universe - but that's another story.
