The concept of free will depends on the definition of “Decision” which might be not so clear after all. The question of “free will” is valid if only we accept that we can make a decision and we can make one of the possible options happen. However the new quantum physics believes (or at least hypothesizes) that almost what ever is possible happens and we feel like there is one of them happening as we observe only one of the infinite realities. If this theory if correct, then it means that we don’t decide which option to chose, rather we randomly continue our existence in one of the multiple realities created after each event! This gives us an illusion of decision making and free will while we have in different parallel reality chosen another option.
