Here is a thought.
Let us assume the there is an infinite uni-directional line of balls. And it is being jumbled up again and again, randomly. (say by 'God'!)
I in my limited experience/capacity can 'observe' only 10 balls. And I see that the positions of balls alternate in pairs. Say if balls are numbered 1 to 10, ball at position 1 takes 2 position and 2 comes to 1's position and this keeps repeating. And similarly for balls (3,4) to (9,10) - I call this pattern a 'Law' - "Balls alternate with their immediate following neighbor if they are at odd position or with their immediate preceding if they are at even position". (That such a pattern will be there is guaranteed by the fact the line of balls is infinite and jumbling is random - an assumption about infinity and randomness)
Assume suddenly I'm able to observe 20 balls and the above rule breaks - so I come up with another cleverer rule that applies to all 20 balls and claim this is the 'new' universal law.
But in reality / in totality there is 'no' pattern - there is 'no' law - there are just local patterns that emerge in this game which is actually 'random'.
Is the above a valid way of looking at Physics? What are the arguments against it? How can we be sure that there are universal laws without having the capacity to observe the entire universe?
