Now, I might be wrong, but I believe that our universe is also a result of serendipity. And out of this is born the fundamentality of probability. Everything is not deterministic as we would likt them to be. And whatever we perceive to be deterministic always has some amount of probability intrinsic to it however we may try to ignore.
This leads me to ask, is it the deterministic nature nature of the universe which leads to serendipity or the probabilistic nature?
Had it been a completely probabilistic Universe, it would be child's play to convince ourselves about the serendipity. Serendipity is an embodiment of the chance - the very basis of the probabilistic theory.
So, now the real question is whether Deterministic Theory account for serendipity. Now any layman might raise this very valid question, if the universe is deterministic, there is no chance then how can serendipity be applicable. I would tell him thus, It is the determinism in this universe which ensures that a person does what is expected of him in spite of the million decision he takes to avoid it. All the what if's that could have gone the other way went the other way but still he managed to come back to the right road? that would be the essential nature of the deterministic world again. The end has to be predetermined and certain in spite of any deviations that may occur in between.
Serendipity may be borne out of either universes but it is an essential part of our life and this is what makes our life infinitely more interesting even amidst our drab daily activities.
