Gravitational Alternative. "The (only known; geometric; metrically spatial) definition
for physical dimensions begins with no dimensions whatsoever  specifically a geometric point. We will call it 'point zero
('0'). Any motion of point '0' will inevitably be at right angles from itself, and, any motion, at any speed, for any length
of time, generates a One Dimensional Straight Line 'O'  'A', of arbitrary length. It cannot be a curved line yet because it
has no dimension(s) to curve into. It may become a longer or shorter One Dimensional Straight Line, but it cannot change
its dimensional quality until it moves at right angles (90 degrees, perpendicular) from itself (again). Then it generates a
Two Dimensional Plane 'A' 'B'. When a Two Dimensional Plane ('A''B') moves at right angles to itself (yet a third
time), it generates a Space and/or Solid 'B''C' of Three Dimensions (Picture a linedrawn cube; progressively generated
from 0 dimensions to 3Dimensions: by the right angle extrapolation of the geometric point ‘0’, to ‘0’’A’, generating a
One Dimensional Straight Line . The Straight Line ‘0’’A’ then moving at right angles to itself, generating
‘A’’B’ Two Dimensional Plane. The Two Dimensional Plane ‘A’’B’ moving at right angles to itself ‘B’’C’; generating
a Three Dimensional Solid, occupied or occupiableby 3dimensional matter). "Of course, the rule here is the right
angle/perpendicular projection of each dimension from out of the preceding dimension. This is how physical dimensions
are generated, hence this is their singular physical and philological definition. That leaves us here and now with the
conceptualgeometric credentials to contemplate the Three recognizable Dimensions of Space occupied  or occupiable 
by matter. A familiar enough concept; byway of its Universal physicalconditional manifestation in the entire reception of
physicalsensory, instrumental and therefore psychologicalconceptual human experience (at large). Knowing; not
speculating, that we are obliged by the laws of geometry, combined with Einstein's (allegedly 'acknowledged') proof that
the entire physical Universe is 4Dimensional: not merely to 'consider', but to find the physical as well as spatial Three
Dimensions of Space moving at right angles from themselves. This is not a mere idea, or consideration, or project; it is an
ultimatum. THE 4DIMENSIONAL ULTIMATUM.
