My point in bringing up the light meter is that in these "tree falls in the forest" thought experiments, it's taken for granted that your own biological senses are an absolute source of truth.

But your eyes are just another set of equipment, similar to a light meter. Just because your eyes are attached to the rest of your body, it doesn't make them inherently more trustworthy than equipment that's not part of your body.

However, our expectation is that a tree falling in the forest could kill us even if we didn’t hear and see it. That’s why we look when we cross the road. The fact that we’re subject to all sorts of things that can cause us harm without sensing them makes the case a lot more compelling that the light meter exists when we blink.
