We occasionally encounter people who believe in destiny to the extent that they believe that they don’t have free will. Everything was fixed at the moment the Universe was created, and they maintain that if you had a computer powerful enough you could know the precise position of every atom in the universe and thus predict everything that was going to happen. I am not enthusiastic about that view of the way things work!
The mass of the Universe is around 1.5*10^53 kg. The mass of my brain, the source of my free will, if I have any, is about 1 kg and it controls about 100 kg of my bodily matter directly and when driving my VW beetle it was about 1,000 kg. Thus, my control over the Universe is very roughly one part in 1.5*10^50.
However, my control over my immediate physical self which affects my immediate environment is almost 100%. Okay, I can’t levitate. I must obey the laws of the Universe, and the social laws, and lots of other things too, but what I can do, I can do freely. Over the very tiny bit of the Universe, and a small part of my personal locality and time, I do have a bit of control. It is tiny, but it is real, I think!
Now for the kicker. If I am successful in influencing, even in a very small way, the ideas for helping the Universe to self-actualize its, unknown at the moment to me, potentials, I will be exerting my free will upon the whole of the Universe. Even if these plans were totally successful and we could launch some robots at near the speed of light they might not reach the limits of the currently visible Universe, and some might quibble therefore I can’t control it and thus have no ultimate free will.
Just because I can’t stop a black hole from absorbing stuff, like information, doesn’t mean I don’t have the power to influence those things that aren’t swallowed up into it.
I’m comfortable with the free will which I do have and will use a portion of it to help the Universe transition into its next potential state of being.
