The article examines some philosophical issues related to linkage between quantum mechanics and general relativity theory. Attention is drawn on the linkage of these theories with the units of measurement for time, length and weight computed by the physicist Max Planck at the beginning of XX-th century. With these values which have acquired meaning in modern physics theories, we are trying to conceptual approach to that primordial singularity from which, according to Big Bang theory, exploded all known fundamental forces. Both theoretical physics researches and philosophical reflections are oriented to knowing that world – which is the single origin of the universe.
