The probability of this being another probability question

Is 100%. Can someone tell me if below is a new idea?

In a closed system, at time t+1 the set of all possible future events is smaller or equal to the set of all possible future events at time t.

Because:

- Things that are possible can become impossible
- Things that are impossible can’t become possible
- So the probability space shrinks with time

A good example of this is the 2nd law of thermodynamics; heat death of systems etc...

Sure, makes sense. Not very deep idea though...

Sure but it’s widely applicable especially in connection with infinity and the old saying ‘anything that can happen will happen’. Rules out Boltzmann Brains for example
