Thats what I mean. Use a machine. Lets say there is such a thing as pure chance. Everything in the universe has an element of randomness to it. If you flipped a coin in the exact same way twice there would be tiny diferences in the results. If there was such thing as chance it would also be possible to do the exact same experiment 10 times, 9 times it would be exactly the same, 1 time it would vairy. I am not making any sense. It is hard for me to articulate what I am thinking. Maybe this will make some sense:
Everythig in the universe is partly governed by chance, the farther the deviation is from the norm, the less likely it is to happen.
I am sure a scientist has come up with something like this.
