If we believe in the Big Bang Theory – and the universe’s continuous expansion is a strong indication that such theory must be correct – the initial state of the universe was a single point (known as a singularity) that then expanded to the cosmos we know and perceive today, which, of course, includes us.
If so, there is a causal relationship between the Big Bang and us. In other words, free will is not allowed, and all of our actions are just a mere consequence of that first event. Such a view is known as “determinism”, or “super-determinism” (if one finds it productive to reinvent the wheel).
If we believe the initial state of the universe to be quantified by a rational number, we are inferring that it is periodic, non-chaotic and globally predictable in nature. But if the initial state is rather quantified by an irrational number, we are instead inferring that the universe is aperiodic, chaotic and therefore only locally predictable in nature.
