We are stuck in a kind of Tautology principle; that we have to trust that the cat stays alive as we planned for it to be. Linear cause and effect science and reasoning drops off and we are stuck with faith that things will continue as we have always observed them to continue and dead-end our reasoning and experimentation modelling along that path. Or we continue our searching combining both faith and reason, being open to an ever enlarging expanding universe.
Proverbs 16:33 has much to say concerning this article and one can even derive a kind of principle from it. All structured reality and it’s quantum substructures remain unaltered unless acted upon by an intervening agency.(a kind of quantization of the laws of inertia)
Proverbs 16:33 The dice are thrown, but the Lord determines every outcome!
