The current understanding of theoretical physics tells us that there exists a unique, nonperturbative quantum theory living in 11D spacetime (M-theory), from which five 10D superstring theories arise as perturbative limits Finding the explicit form of this M-theory is one of the greatest theoretical challenges of the twenty first century. In this thesis, we shed the light on some important aspects, vacuum energy, moduli stabilization and gaugino condensates in the framework of 5D heterotic M-theory. The central question we are trying to answer in this, thesis is: what is the mechanism for radion stabilization?. To answer this question we calculate the total bulk vacuum energy, which is the difference between the twisted and untwisted fermion vacuum energies. in both flat and curved spaces.
