The inflationary phase of the evolution of the ten dimensional universe is considered.
The form of the stress-energy tensor of the matter in the very early universe is
determined by making use of some thermodynamical arguments. In this way, the Einstein
field equations are written and some inflationary cosmological solution is found
to these equations in which, while the actual dimensions are exponentially expanding,
the others are contracting.

A simple calculation is made where the zero-point energy is obtained for a spherical Casimir
cavity the size of the classical electron radius. The result is found to be roughly equivalent to the
rest mass-energy of an electron-positron pair. A discussion is provided from this that suggests a
possible contributing mechanism for pair production. It is suggested how the virtual spherical
cavity could come about in the presence of a background E&M field and that such cavities could
be viewed as a dynamic virtual potential energy field.

Born�s Reciprocal Relativity in flat spacetimes is based on the principle of a
maximal speed limit (speed of light) and a maximal proper force (which is also
compatible with a maximal and minimal length duality) and where coordinates
and momenta are unified on a single footing. We extend Born�s theory to the case of
curved spacetimes and construct a Reciprocal General Relativity theory (in curved
spacetimes) as a local Gauge Theory of the Quaplectic Group and given by the semidirect
product Q(1, 3) x U(1, 3)
sH(1, 3), where the Nonabelian Weyl-Heisenberg
group is H(1, 3). The gauge theory has the same structure as that of Complex
Nonabelian Gravity. Actions are presented and it is argued why such actions based
on Born�s Reciprocal Relativity principle, involving a maximal speed limit and a
maximal proper force, is a very promising avenue to Quantize Gravity that does
not rely in breaking the Lorentz symmetry at the Planck scale, in contrast to other
approaches based on deformations of the Poincare algebra, Quantum Groups. It
is discussed how one could embed the Quaplectic gauge theory into one based on
the U(1, 4),U(2, 3) groups where the observed cosmological constant emerges in a
natural way. We conclude with a brief discussion of Complex coordinates and Finsler
spaces with symmetric and nonsymmetric metrics studied by Eisenhart as relevant
closed-string target space backgrounds where Born�s principle may be operating.
