Bringing Together Gravity and the Quanta

Abstract

Due to its underlying gauge structure, teleparallel gravity achieves a separation between inertial and gravitational effects. It can, in consequence, describe the isolated gravitational interaction without resorting to the equivalence principle, and is able to provide a tensorial definition for the energy-momentum density of the gravitational field. Considering the conceptual conflict between the local equivalence principle and the nonlocal uncertainty principle, the replacement of general relativity by its teleparallel equivalent can be considered an important step towards a prospective reconciliation between gravitation and quantum mechanics.Comment: 9 pages.

Conserved currents in gravitational models with quasi-invariant Lagrangians: Application to teleparallel gravity

“…Tetrad frames differing by a local Lorentz transformation are related to different Lorentz connections. A connection includes both inertial and gravitational effects [24]. While the gravitational effects produced by compact sources vanish asymptotically, the inertial effects can grow up at large distances.…”

Teleparallelism: A New Insight into Gravity

“…This expression shows explicitly that, in such a local frame inertial effects (left-hand side) exactly compensate for gravitation (right-hand side) [20]. The possibility of separating inertial effects from gravitation is an outstanding property of teleparallel gravity.…”

Physical Quantities of Reissner-Nordström Spacetime with Arbitrary Function and Regularized Procedure

“…An important difference between Einstein theory and teleparallel theories is that it is possible to distinguish gravitational field from inertia [18]. With the purpose of getting a deeper insight into the covariant teleparallel formalism, Lucas et al [17] reanalyze the computation of the total energy of two models.…”
