As I said before, you can simulate a nuclear explosion, but that simulation will never manifest itself into a real nuclear explosion.

There's a physical basis for most things. A magnetic field forms because you have a bunch of particles with the same quantum spin. A stove burner glows red when you run electricity through it.

I'm not saying the process in the brain is unique. I'm not saying there's only one way to "activate" consciousness. Heck, for all I know, maybe a bolt of lightning experiences consciousness, even if just for a fraction of a second.

Allow me to give you a "physical" example. The brain operates near a critical threshold, that is the edge of chaos. The brain is teetering on the edge of chaos without ever going chaotic. Well, not usually, because when the brain does enter chaos, you get a seizure. But there is growing evidence that this may be a prerequisite for consciousness; when the brain enters a less chaotic state, a person may lose consciousness.

Now let's talk about information processing. Most of what our brains do is subconscious. Only a small subset of what our brains do is actually conscious. What makes some information processing more special than others that some of it is conscious and the rest is not? Isn't it more likely that the way the information is processed is what makes the difference? I.e. different at a physical level.

The nuclear explosion analogy is a bit off since for anything living in the simulation the nuclear explosion would be quite real. The explosion isn't real for us in the physical world because it cannot interact with us, but a simulated mind can interact with us in the real world.

This is an excellent way of approaching the question, but I just as easily can say isn't it more likely that the difference is the pattern of the information and not the strict physical structure that makes it? Look at how many different physical structures and mechanisms we have for seeing, hearing, breathing, touching, etc across nature. Many of them are fundamentally different from each other, but end up in the same result of a sense.

Isn't it more likely that conscious thinking is like other senses in that it's a kind of information processing, rather than a specific mechanism of processing?

This also make it more likely to answer your question of why are some mental processes conscious and the majority are not, it would seem far more likely that the brain's neuronal structures (most of which are the same basic cell throughout the brain, just in different types of structures) discover different patterns rather than fundamentally different physical processes.
