Why use the word 'must'.
In fact what you are saying makes no sense.
​
Explain it more thoroughly.

2 analogies that should be banned or at least..
used more carefully in physics:
​
1) The rubber sheet/balloon for representing spacetime
​
2) Decks of cards and similar analogies for order/disorder and thermodynamics
​
Balloons invariably lead to questions of "well what's inside the balloon" with people thinking about spacetime embedding in higher order spaces when there is no evidence of such.
​
Decks of cards and macroscopic order has nothing to do with entropy and by inference the 2nd law of thermodynamics.
