The generalization of
Einstein’s special theory of relativity (SRT) is proposed. In this model, the
possibility of unification of scalar gravity and electromagnetism into a single
unified field is considered. Formally, the generalization of the SRT is that
instead of (1+3)-dimensional Minkowski space the (1+4)-dimensional extension G is considered.
As the fifth additional coordinate the interval S is used. This value is saved under the usual
Lorentz transformations in Minkowski space M, but it changes when the transformations in the
extended space G are used. We
call this model the extended space model (ESM). From a physical point of view,
our expansion means that processes in which the rest mass of the particles
changes are acceptable now. If the rest mass of a particle does not change and
the physical quantities do not depend on an additional variable S, then the electromagnetic and gravitational fields
exist independently of each other. But if the rest mass is variable and there
is a dependence on S, then these two fields are combined into a single unified
field. In the extended space model a photon can have a nonzero mass and this
mass can be either positive or negative. In this model the 5- vectors which
components correspond to energy, pulse and mass of a particle are isotropic
both for massive and massless particles. The rotations in the (1+4) dimensional
extended space G can transform
massive particles into massless and vice versa.
