Though at macroscopic scale a property of an object indeed is what the dictionary says it is, something it privately owns, only the cause of its interactions, independent from interactions, here the observer doesn't affect the observed in a perceptible manner. If, as classical mechanics, big bang cosmology and general relativity assumes that the properties of objects are eternally unchangeable, they obviously can, in principle, be observed without being affected by the observation, so in this, outdated, view, there indeed exists an objectively observable reality at the origin of our observations: as Einstein said: ''We all, more or less in the same way, say that a rose is red, smells like perfume, and feels like velvet. In other words, there is an objective reality which is conceived by the senses, and behind this objective reality are natural laws which are the privilege of the scientist to discover.'' However, things are entirely different at quantum level: if particles are both cause and effect of their interactions so the particles of the rose and those of the observer contribute to each other's energy, each other's properties, then he cannot observe the rose as it is since without his own existence it wouldn't be the exact same rose. Though as a rose is a macroscopic object, the effect of the observer on the rose is negligible, at quantum level an observing particle does affect the observed particle to the extent they are 'made out of each other', exchange energy. Einstein continues: ''Nature doesn't know chance, it operates on mathematical principles. As I have said so many times, God doesn't play dice with the world.'' Though despite this statement, he said that he didn't believe in God, in insisting on causality, on determinism (which made him reject quantum mechanics), he actually did, the result of which is that general relativity in its adaptation to big bang cosmology became corrupted.
I am well aware that what I propose constitutes a completely different paradigm so cannot be understood very well in the terms of the present one: ''To adopt a new theory or paradigm means to accept a completely novel conceptual scheme that has so little in common with that of the older; now rejected, theory that the two theories are "incommensurable," for no objective yardstick exists that makes it possible to compare them. Furthermore, as the meaning of every scientific term in a given theory depends upon the theoretical context in which it occurs, even the individual scientific terms of the new theory are incommensurable with the terms of the old one, despite the fact that the same terminology is often retained.''
