On Geometry, Topology, Cosmological Constant, Special and General Relativity
The complementary aspects of the geometric and topological structures of a mathematical space is pointed out. The same is used to get a deeper understanding of the much abused Cosmological Constant. This brings in its wake a consistent and physical understanding of what a ”test particle” in General Relativity really is. This helps us to also understand as to what one actually means when substit...
متن کاملUnimodular relativity and cosmological constant
Unimodular relativity is a theory of gravity and space–time with a fixed absolute space–time volume element, the modulus, which we suppose is proportional to the number of microscopic modules in that volume element. In general relativity an arbitrary fixed measure can be imposed as a gauge condition, while in unimodular relativity it is determined by the events in the volume. Since this seems t...
متن کاملSpecial relativity with a preferred frame and the relativity principle: cosmological implications
The modern view, that there exists a preferred frame of reference related to the cosmic microwave background (CMB), is in apparent contradiction with the principles of special relativity. The purpose of the present study is to develop a counterpart of the special relativity theory that is consistent with the existence of a preferred frame but, like the standard relativity theory, is based on th...
متن کاملCosmological Constant, Conical Defect and Classical Tests of General Relativity
We investigate the perihelion shift of the planetary motion and the bending of starlight in the Schwarzschild field modified by the presence of a Λ-term plus a conical defect. This analysis generalizes an earlier result obtained by Islam (Phys. Lett. A 97, 239, 1983) to the case of a pure cosmological constant. By using the experimental data we obtain that the parameter ǫ characterizing the con...
متن کاملGeneralized Gauge Theories with Nonunitary Parallel Transport: General Relativity with Cosmological Constant as an Example
In gauge theories parallel transporters (PTs) U(C) along paths C play an important role. Traditionally they are unitary or pseudoorthogonal maps between vector spaces. We propose to abandon unitarity of parallel transporters and with it the a priori assumption of metricity in general relativity. A ∗-operation on parallel transporters serves as a substitute for it, and this ∗-operation is proven...
