  Gravitation is the common underlying texture between General Relativity and
Quantum Mechanics. We take gravitation as the link that can make possible the
marriage between these two sciences. We use here the duality of Nature for
gravitation: A continuous warped space, wave-like, and a discrete quantum gas,
particle-like, both coexistent and producing an equilibrium state in the
Universe. The result is a static, non expanding, spherical, unlimited and
finite Universe, with no cosmological constant and no dark energy. The
Principle of Mach is reproduced here by the convergence of the two cosmological
equations of Einstein. From this a Mass Boom concept is born given by M = t, M
the mass of the Universe and t its age. Also a decreasing speed of light is the
consequence of the Mass Boom, c = 1/t, which explains the Supernovae Type Ia
observations without the need of expansion (nor, of course, accelerated
expansion). Our Mass Boom model completely wipes out the problems and paradoxes
built in the Big Bang model, like the horizon, monopole, entropy, flatness,
fine tuning, etc. It also eliminates the need for inflation. Finally the
relation proposed by Weinberg in 1972 is here explained in terms of a
gravitational cross section for all gravitational masses.
