Causality, Probabilities and Destiny

Read couple of papers[1][2] on probabilistic causality which got me thinking :) How much in control are we of our surroundings?

For every little thing has causation in every other little thing. And more importantly I, me is part of everything. One with the universe ?
That's a nice tag line but is it really true? Long since my childhood have I believed in this oneness at least on some levels. Most of my arrogance (and some of my pride[3]) originates in the belief that I make things happen. But hard was it to realize the pitfall of this "Center of universe" theory. Its more or less like classical model of universe. Every point in the universe is potentially at the center of the universe. Like every point on the surface of the balloon.
This to a casual observer argues for the steady state theory of universe, every point at equilibrium being attracted with equal force from every direction. But the BIG pitfall of this argument is that take a star system which is collapsing on its own (or expanding doesn't matter) and add more or less uniform number of stars filling up rest of the universe. The stars system still keeps collapsing.
So what does this translates to? That universal fabric does not guarantee smoothness. The fact that I have influence on everything happening around, does not itself give me any chance of actually controlling it. Mostly because converse is also true, that every other thing influences me, so no control what so ever is inferred. And unless I have reason to believe I am in some ways special I have no dominion over anything around me.

And that brings us to the topic of destiny. Does the above mean everything is just destiny or probabilistic causality deciding things for me? And although not backed by observable experiments (yet?) multiverse theories do provide a simpler explanation that all those probabilities actually exist and are not selected against at all except for the original causality.
Getting back to practical reality. How much in my life, the human society or even life on earth was actually a choice of a free will? If you watch James Bruke's Connections Series [4] you will probably, like me, conclude that nothing is worth planning for, cause nothing will ever happen the way we chose it. But also nothing will ever happen, if people didn't plan anything at all. Even if those plans never worked out quite, it instead always made 1 + 1 = 3. Tadda !! the creation. And the destiny gets replaced by ummm... hope?

To give it another spin, there are some things we perceive as completely out of our control. I have no real reason to conclude that I will ever end up going to mars. Is this my fate? my destiny? or just causation of my choices? To give a striking example of how that gets easily replaced by one's own choices is Elon Musk. He probably had even less reason to believe such a silly thing when he was 30+, and he did not even have any elon musk or spacex to look forward to. And yet he did make plans to go to mars, executed on them and now has a real chance to do so. So was it really my destiny to never go to mars? Or is it my own doing? Of course to argue against it neither me or elon musk have any practical chance of making it to the local planning commissioner[5] at Alpha Centuri but then again is it just that we have chosen not to?

And finally why would anyone chose to read thru this article and actually reach the end? Dont blame yourself its your fate.
