Abstract: The place and physical significance of gauge gravitation theory in the Riemann-Cartan space-time (GTRC) in the framework of gauge approach to gravitation is discussed. Isotropic cosmology built on the base of GTRC with general expression of gravitational Lagrangian with indefinite parameters is considered. The most important physical consequences connected with the change of gravitational interaction, with possible existence of limiting energy density and gravitational repulsion at extreme conditions, and also with the vacuum repulsion effect are discussed. The solution of the problem of cosmological singularity and the dark energy problem as result of the change of gravitational interaction is considered.
The article discusses the significance of gauge gravitation theory in the Riemann-Cartan space-time (GTRC) within the gauge approach to gravitation. It explores isotropic cosmology based on GTRC and examines the physical consequences related to the change of gravitational interaction, including the potential existence of limiting energy density and gravitational repulsion under extreme conditions. The article also discusses the vacuum repulsion effect and how it may contribute to solving the problem of cosmological singularity and addressing the dark energy problem.
Future Roadmap
Looking ahead, there are several potential challenges and opportunities on the horizon:
1. Experimental verification
One of the key challenges is the experimental verification of the predictions and consequences of gauge gravitation theory in GTRC. This will require designing and conducting experiments that can accurately measure and observe the effects of the change in gravitational interaction, as well as the potential existence of limiting energy density and gravitational repulsion. Collaborations between experimentalists and theorists will be crucial in this endeavor.
2. Further theoretical development
The article indicates that the gravitational Lagrangian in GTRC has indefinite parameters. Further theoretical development is needed to fully understand the implications of these parameters and their relationship to the observed physical consequences. This may involve mathematical modeling and simulations, as well as innovative theoretical frameworks and approaches.
3. Cosmological implications
If the change in gravitational interaction leads to the solution of the cosmological singularity problem and addresses the dark energy problem, there may be significant implications for our understanding of the universe. Future research should investigate these implications in more detail and explore potential connections to other cosmological phenomena, such as the expansion of the universe and the formation of structures.
4. Practical applications
Understanding and harnessing the effects of gravitational repulsion and the vacuum repulsion effect could have practical applications in various fields. For example, it may lead to the development of advanced propulsion systems or contribute to the design of new materials with unique properties. Exploring these practical applications may open up new technological possibilities and benefits.
5. Interdisciplinary collaborations
Gauge gravitation theory in GTRC spans multiple disciplines, including physics, mathematics, and cosmology. Encouraging interdisciplinary collaborations and fostering knowledge exchange between different scientific communities will be essential in making progress and addressing the challenges and opportunities associated with this theory. Conferences, workshops, and collaborative research projects can facilitate such collaborations.
In summary, the roadmap for readers of this article involves experimental verification, further theoretical development, exploration of cosmological implications, investigation of practical applications, and interdisciplinary collaborations. By addressing these challenges and leveraging the opportunities, we can advance our understanding of gauge gravitation theory in GTRC and its potential implications for our understanding of the universe and technological advancements.
