Is the universe naturally chaotic, or does it run like clockwork?

It is naturally chaotic. However, with energy unevenly distributed, this allows for systems to function and work to happen. When a system has less order, it is called entropy. The Universe is constantly moving closer to a uniform energy, leading to complete entropy.

You're mixing up the mathematical and common-usage meanings of the word 'chaotic'. Mathemetically, your basic chaotic system is actually completely deterministic, it's just that very small changes in the initial conditions can lead to very large changes in the final conditions - but the system itself can appear fairly simple and well-defined (for example, look up the double pendulum).

The world is described as chaotic because many systems within it, e.g. the exact pattern of cloud formation in a region, can be drastically changed by small initial differences in the starting conditions which is why they're so difficult to forecast. However, even with that in mind general predictions can be made such as 'there will be patchy cloud tomorrow'.

Interesting.

So there's no such thing as true randomness?
