Schrödinger's Dog

So a few days ago I was out walking in the morning. On the Beaumont trail behind the apartments heading for the Beaumont Parkway crossing, there was a little old woman pushing a baby carriage coming the other way. So what was in the carriage? A baby or a dog? For a woman that age, I would estimate both were equally likely.

As we passed, I did not turn and look. I did not collapse the wave function. I have no idea which it was. And if Penrose was right (probably not) and there are quantum tubules in our brains helping to create consciousness such that my decision not to look may have had a quantum component, does that mean that the baby/dog states both currently exist?

Of course, the woman was looking at the carriage interior the whole time. So she collapsed the wave function. So it was definitely a dog or a baby and not a quantum superposition of both.

Not sure I have blogged it, I'll mention it again: maybe the whole "observer collapsing the wave function" thing is a consequence of the fact that we are living in a simulation, and the simulation does not bother to compute and render things that no one is looking at. I'm totally not sure if that has any explanatory value or not. But maybe it does imply that once 1 observer collapses the wave function, it is collapsed for all observers. Seems intuitive, I guess.
