cross,parallel, and wall-eyed viewing

[P3D Gabriel Jacob <jacob@xxxxxxxxxxxxxx>]

In the same issue of Pop Science that I mentioned before (Dec.96) there
is another article called FYI (for your information). It is in a 
question and answer format. In it one of the questions is ,"Why can we
cross our eyes inward but not outward?".
The response they give is as below.

>>We certainly have all the nerves and muscles needed to make our eyes
move outward, otherwise we'd never be able to look sideways. but we can't
simultaneously turn them outward, because that's not on the list of brain-
approved activities. Eyes straight forward is the position that offers
the maximum field of binocular vision. To see something up close, though,
the eyes automatically turn inward a bit-crossing your eyes is merely an
extreme tension of that action. but if both eyes were to turn outward, 
binocular vision would be lost, something the eyes, "central control
won't allow," explains Dr.William Power, an instructor in ophthamology
at Harvard Medical School.<<

This can be found on page 120. Now I am puzzled. Most people here on P3D
can freeview cross-eyed and parallel-eyed, including myself. But viewing
wall-eyed (not sure if this is the proper term) or with both eyes turned
outward, is harder. Plus I thought that 3d would still be observable. I
remember that (Bill Ewald from Kodak) it was mentioned that, one could
see beyond "infinity" by diverging ones eyes. If one did that and looked
up at the stars it was mentioned that the stars would look closer to
oneself. Now is this correct or is the above passage correct? Or are they
both correct?!

Gabriel going out to consult with the stars.
