The reason is simple, every time the fluctuations are caused by the collision the universe would be born of totally different values, the cosmological constant would be different and life may not be able to arise. But life has arisen and the only way to explain that is if the branes had collided enough times for the chances of life to come into being occur.

And what underlying truth is it that you are referring to ? You can only measure something that exists in substance or has a physical representation that causes an effect such as energy or mass.
You can not take measurements of theories, concepts or factless ideas.

I wouldn't get so excited just yet. This theory is wrong like all the others. At best it's an approximation whose range of validity has yet to be determined, just like the standard model. One thing that makes me skeptical is the total failure and damage that string theory has done to modern physics.

Many issues remain open. Among these are: the calculation of non-diagonal terms in the propagator [47]; the precise physical interpretation of the two expansion parameters, λ and 1/jL [22]; the physical interpretation of the numerous subdominant terms, and their relation with the relativistic and the quantum corrections to the Newton law
[9]; a clarification of the implementation of the SO(4) → SO(3) gauge fixing at the boundary [48] and of the overall Lorentz invariance of the
formalism [49]; a precise formulation of the physical meaning of the observability of the boundary geometry (which is a partial observable [12, 50, 51, 52]);
the possibility of computing general covariant n-point function for models without expansion parameter λ; the full exploration of the dynamical WdW condition (53) on the boundary state.
