Destiny is a tricky topic and often a boring one too. There are those who believe that all our lives are pre-written and then there are those who think we create our destiny by our skills and hard work. I am not going to get into a debate over this, nor am I going to impose my beliefs on you. I do come from an extremely religious family and happen to be a firm believer of destiny. But in this post I am not going to discuss about the things which I learnt from my grandparents not would I discuss our ancient scriptures. I would stick to the things we learnt in school. I will stick to the laws of motions and the chemical reactions we memorized during our JEE preparation days. I would somehow try to make sense of the things all of us learnt in school and college. Being among the "below average" performers during my college days there might be some loopholes in the below line of thinking and I would really appreciate a healthy debate. (Don't be too harsh on me as I am the only one who has the access to delete other's comments on this blog)
So let me begin with telling you why I think a bunch of smart guys with a few Param computers can predict future. Well we know that whatever we do, whether its moving our hand, picking up a book, watching television, or just sitting is governed by the instructions our respective body parts get from our brain (Spine in case of involuntary actions). The instructions are electric signal which are passed through our neurons. The electric currents are produced in the brain cells as a result of specific chemical reactions. So basically these chemical reactions govern each of our actions. Since a 'thought' too is just and an electric current, even what we think while sitting idle is decided by the chemical reactions in our brain. Similarly the actions of others too are governed by the chemical reactions in their brains. Now to go further, these chemical reactions are governed by the collision of atoms and molecules in our brain. The collision and motion depends on the trajectory and velocity of these particles and also on the external forces applied due to other atoms and molecules. Now if I know the position and velocity of each atom as of now (provided Mr. Heisenberg focuses on my intent and does not play spoil sport), and also know the strength of different field forces applied, then I can predict there velocities and positions five minutes from now. Which means I can predict what someone would think and do after five minutes. This way, by considering the situation as of now and by doing some out of the world calculations, I can successfully predict the future. But the real fun is not in knowing what lies ahead, the real fun is in going backward in time.
Big Bang and Destiny
Based on the above, I can assume that the fact that you are reading this blog could have been predicted 5 minutes ago. And if I take my calculations even further then this could have been predicted even years ago. Infact as long as were are talking in terms of forces and trajectories, we can say that what is happening today could have been predicted at the time of big bang when all the matter around us was put into motion. Looking at the position and velocities of object just after the big bang, someone could have predicted the scene and events of today. Now this scares me. The fact that what I will do or even think about doing was already decided many many centuries ago is a scary thought. What it essentially means is that we have no control on our lives or even our thoughts. It means that it was decided centuries ago that this idea would come to my mind and then I would write about it. The fact that you will be reading this too was decided at the time of big bang itself.
So, the life we are living today is just a movie which was shot long time back. Its just that we are watching it now. The only thing you can do now is to either keep trying to change the movie which was shot long back or grab your popcorn and enjoy the show.
PS: Whether you decide to watch your life as a spectator or not too was decided long back. So don't bother yourself too much with the idea.
