Solving the singularity problem

[wolram]

I admit i know little about this subject, but am interested in any thing that solves the singularity problem.
May be some one will look at this paper to see if it makes sense

Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover, recent works have shown the crucial role of the NED on the inflation. This paper provides a new approach based on a new model of NED as a source of gravitation to remove the cosmic singularity at the big bang and explain the cosmic acceleration during the inflation era without initial singularity on the background of stochastic magnetic field. We explore whether a NED field can be the origin of the cosmic acceleration. Also, we found a realization of a cyclic Universe, free of initial singularity, due the model for the NED energy density we propose. We find explicit relations for H(z) by direct integration of the equations of motion of the proposed model. We perform MCMC likelihood exploration of these relations using Observational Hubble data to find the mean values for the NED parameters. We compute the deceleration parameter q(z) in the range 0<z<2 from the best fit values of the parameters and find q(z)→1/2 at z→∞. Moreover, the Universe passes of a decelerated phase to an accelerated stage at redshift ∼0.5. The result is that the are not statistical differences with the usual model during the radiation epoch which holds for α=0. However, taking α slightly different from zero, we find that the NED with dust matter (wm=0) is able to drive the late-time cosmic acceleration of the standard cosmological model.

I am always interested in exploring new ideas and theories in order to further our understanding of the universe. I have not yet had the opportunity to review this specific paper, but I will definitely take a look at it and see if it makes sense in the context of current research and theories.

The concept of using nonlinear electrodynamics as a source of gravitation to resolve singularity problems and explain cosmic acceleration is intriguing. However, it is important to thoroughly evaluate and test any new model or theory before accepting it as a solution to a complex problem like the singularity.

I appreciate your interest in this subject and I encourage you to continue exploring and discussing ideas with others in the scientific community. Collaboration and open-mindedness are key to advancing our knowledge and solving complex problems.
