now we have a new challenge: what is a “measurement,” anyhow? Does a measurement require a measurer? Does the quantum world depend on whether it has an audience? Can anyone at all collapse a wave function? Do you need to be awake and conscious for it, or can a comatose person do it? What about a newborn baby? Is it limited to humans, or can chimps do it too? “When a mouse observes, does that change the [quantum] state of the universe?” Einstein once asked.
