Are Singularity and Dark Energy Consequences of Vacuum Solution of Field Equations?

Modern physics is trying to solve problems like singularity, dark energy and universe expanding by using sophisticated methods in particle and quantum physics. But, the mentioned problems should also be solved in the classical General Relativity Theory (GRT). As it is well known, Schwarzschild solution of the Einsteinrsquos field equations is in fact a vacuum solution. Unfortunately, this vacuum solution generates appearances as singularity and dark energy with unknown source. Here we show that the singularity and dark energy with unknown source are direct consequence of the vacuum solution of the Einsteinrsquos field equations. In that sense we employ new Relativistic Alpha Field Theory (RAFT) that proposes solution of the field equations without appearances of singularity and offers the source of dark energy. This is the consequence of the following predictions of RAF theory: a) no a singularity in a gravitational field and b) the gravitational force becomes positive (repulsive) if (GM/rc2) gt 1, that could be the source of a dark energy.
