In the natural world, is true randomness possible?
All things can be attributed to a cause, even if we cannot see it. Take the tree outside my window. The leaves appear to be randomly distributed. But each leaf initiation has a number of factors, such as direction and amount of sunlight, the winds at the time, the state of the tree's nutrition, etc.
Or stars in the sky ... they appear to be randomly distributed even though we look for patterns there. But each one is where it is due to specific factors, even if those factors are beyond our scope.
What about a car accident, is that random? One can trace the path of your car, and whatever you hit, the time you left, the decisions you made, which led to you being in a particular place at a particular time ... and thus in an accident. Is this truly random? It was unplanned, but not random.
So, one could define "randomness" as something that we just do not have enough mind-power to comprehend.
