What the Creation Museum did to me

[Aractus]

The size of the universe is necessary, it's not an accident or chance.

No-one apart from creationists says it was either.

Life is just one (of many) manifestations of physics.

Physics is demonstrable, repeatable, predictable, reliable. Know what else shares these properties? Not your god.

Physics is guided by bias and opinions, you know this. Consider Pi. Pi is a transcendental number, its decimals recess infinitely. But we actually only need the first 11 decimal places. All the practical uses of Pi you would ever need only require the first 11 decimals. Thus you can use Pi = 3.14159265358, isn't that simpler?

According to Occam's Razor the simplest theory is more likely to be correct (although tell that to Einstein). If it was physics, you would derive the number experimentally, and then call it a constant - ah, isn't that much simpler than having an irrational number? Of course it is! According to physics the simpler option is preferred - according to Mathematics, physics can get stuffed because Pi is one of the most complicated numbers known to man.

The universe was structurally different 3 billion years ago. If you don't believe me, then go ask an astrophysicist what the size of the universe is today, and what it was 3 billion years ago. Of course you can't repeat what you had 3 billion years ago, in the same way that it's impossible to re-create the big bang.

The point about chaos thoery is that complex systems will arise from simple systems based on simple rules. And that they are emergent systems.
Please be good enough to explain how determinism comes in to it.

I'll do you one better. Chaos, at its basics, imagines a set of very simple rules from which complexity is derived. Crystallography is one such example, however, of the exact opposite. The starting conditions are randomized, the rules are complicated, but the result ultimately converges into a simple outcome. You can get the same outcome (or similar outcomes anyway) from any number of randomized starting conditions. A random system full of complexity becomes simple when simple rules take over. You can't use a complicated string of rules based on quantum mechanics alone to describe and predict the behaviour of the laws of chemistry - if there is a pathway to those laws, it is too complicated to follow; yet the simple rules are there built ontop of this seemingly impossibly complex inner-structure.

Nobody really knows how the universe works, they simply imagine what might be. Chaos was popular at a time when everyone saw the universe in one particular way, times have moved on and we now know that simplicity doesn't always lead to complexity.
