Not Everything is Possible!

We can only see the past; can't change it. Now people will say that nothing is impossible in this world. Okay. Suppose if I tried to prove this statement wrong, then what? I can't? But the statement itself says that NOTHING IS IMPOSSIBLE. Then to prove this statement wrong is also not impossible.

Let's take a rope which is 6 lac kms long, one end you are holding and the other end is tightened to a cart. You have a powerful binocular by which you are able to see the cart. The rope is tightened. Also at any instant you are pulling the rope, the tension transfers to the cart end at that same instant.

Now, you started pulling it for 2 seconds. The cart which is 6 lac kms far will move. But, you will observe that the moment you are pulling the rope through some distance, the cart will be observed to move with a delay of almost 2 seconds. See! What does this shows? It simply means that at the time you pulled the rope, the cart would start moving. But you saw its motion 2 seconds later.

Replace the rope with a straight, rigid rod. Now pull the cart, the same thing will happen. Next step: while the cart is moving for 2 seconds, without your effort, push the rod for the same distance immediately after you stop pulling. What you'll observe? Even after your push, the cart is still moving towards you for those 2 seconds. And after your push for 2 seconds, the cart starts moving away for 2 seconds (after those 2 seconds). Isn't this indicating towards what I said in the beginning? Yes it is. You were unable to change that thing that you've done earlier; you were just able to see that. You firstly pulled the cart (with rod), and you were able to see what you've done after 2 seconds. But, during those 2 seconds, you were unable to make the cart move back, even after your push.


You did something, you are able to look at its effect, but you are unable to change what you've done.

[NOTE: Hereby considering speed of light to be 3 lacs kms per second. lac= 10^5]
