Take for example, time travel. We humans are incapable of achieving this feat, and this is one of those facts that human beings have been forced to accept. However, we have made time travel possible already for uncountable entities. There's no surprise or shock really.
The modern physicist doesn't depend on exact Mathematics, as much as he/she does on computer simulations. These simulations, encoded through certain logical algorithms basically do the hard work that the human brain would have done. However, there is something extremely powerful about computer simulations. They help us visualise the rhythms and symphonies of our artistic intellect or for the lack of a better expression, our poetic abundance.
Let's take a simple example. Most of us are familiar with particle-based simulations where we specify the forces acting on the particle and the initial/boundary conditions, and evolve the particle from one state to another. Now imagine doing this experiment more than a billion times, and the entire process takes only a few hours! What not can you do with such enormous power?
The truth is, we do anything and everything. The more creative your mind, the greater is the scope ( or should I say, the space?) . Now imagine you have your particle whose dynamics has some kind of randomness. You evolve the system for some time, but then revert the particle back to its initial state. If you are familiar with coding, you know the term for this, as does any other person who is not : loop.
When I say that the particle has been sent back to its initial state, it has achieved what its master never could. It has travelled in time. Now note the randomness in the dynamics. The particle now has a new trajectory until it travels for the same amount of time, when it is made to return to its initial state. It travels in time again!
Oh! The infinite possibilities of righting the wrongs...The promise of eternal youth.
Consider now if you instead had two particles, rather than one, who start not necessarily either at the same place or time, but over the course of their motion intersect each other and only by luck, follow respective trajectories, such that they remain in proximity, for an atypically large interval of time...until one of them is randomly taken back to its initial state.
Isn't it good to have freedom? But what is freedom, really? Who gets to decide about it?
The Creator and the particle(s) play a game of Friends and Adversaries. Like in any other board game, the playmates exist, questioning each other's move, on a stochastic landscape.
It's only by luck that we, me and you, belong to this epoch. Is it upto us to decide whether we get to play the particle or the creator? Or is it dignified to surrender to the randomness of it all?
