The spacetime deformations concept proposes a road to unification of general relativity and quantum mechanics i.e. unifies all interactions, answers the questions: why particles have mass and what they are, answers the question: what is energy and dark energy, unifies force fields and matter, implies new theories like the spacetime deformations evolution. I propose a new definition of matter and energy however not contradictory to current theories but totally contradictory to everyday experience. The new quality here is that the definition is supposed to be free of human being's perception and as far as possible also free of our language and culture limitations. I present also some points of view on computability of the actual Universe. This is a concept of principle (an universal concept delivering a description of nature) and not constructive one (describing a particular phenomenon using specific equations). The concept is background independent (the space has no fixed geometry).
