A theory of gravity based on quantum clocks and moving space is
proposed. The theory is based on the hypothesis of the quantum clock equivalence
principle (QCEP): it is impossible for a locally isolated observer to distinguish between
a red-shift in a moving inertial frame of reference and a red-shift in a reference frame
that is at rest in a field of gravity, if the red-shift is all the information he has. This
allows us to formulate a time-dilatation measurement based definition of the speed of
space in a gravity field. The QCEP is then used to predict the frequency shift of a
quantum clock at rest in a g-field, moving in a closed circular orbit and in free fall.
The cosmological and quantum gravitational possibilities of the QCEP hypothesis are
shortly mentioned.

In this paper we show how relativistic tensor dynamics
and relativistic electrodynamics can be formulated in a
bi-quaternion tensor language. The treatment is restricted
to mathematical physics, known facts as the Lorentz Force
Law and the Lagrange Equation are presented in a
relatively new formalism. The goal is to fuse anti-symmetric
tensor dynamics, as used for example in relativistic
electrodynamics, and symmetric tensor dynamics, as used for
example in introductions to general relativity, into one single
formalism: a specific kind of biquaternion tensor calculus.

M.W. Evans tried to relate the electromagnetic field strength to the torsion of a
Riemann-Cartan spacetime. We show that this ansatz is untenable for at least two
reasons: (i) Geometry: Torsion is related to the (external) translation group and
cannot be linked to an internal group, like the U(1) group of electrodynamics. (ii)
Electrodynamics: The electromagnetic field strength as a 2-form carries 6 independent
components, whereas Evans' electromagnetic construct F^{α} is a vector-valued
2-form with 24 independent components. This doesn't match. One of these reasons
is already enough to disprove the ansatz of Evans.

In recent years there are some authors suggesting that the origin of dark energy, quintessence etc.
can be related to Van der Waals force-type interaction at cosmic scale. [1][2][3] Interestingly, in
this regards, this proposition also reminds us to Prof. Castro-Granik's idea sometime ago that if we
indeed live in the Cantorian spacetime Universe [5], then the effect would be as if the Universe
resembles a large Bose-Einstein condensate.
