…this was actually Albert Einstein’s question, illustrating the absurdity of quantum theory…however, years after the death of both Einstein and his friendly adversary Niels Bohr, sophisticated modern experiments consistently confirm the quantum stuff!
So really; does nature disappear when we are not interacting with it?
“Physics (or science) is not about nature, it is about nature exposed to our observation."
