> What if the universe were entirely empty except for two astronauts. One of them is spinning, the other is stationary. The spinning one feels dizzy, doing cartwheels in space. But which one of the two is spinning? From either astronaut’s perspective, the other is the one spinning. Without any external reference, Einstein argued, there is no way to say which one is correct
There is a 50% chance each is spinning, and we'll know which is correct when an external reference "observes" them. The fact that there's no external reference is what makes this situation be "quantum". If the conscious astronauts are conceptually incapable of being 50% "feeling dizzy", then that would mean conscious beings also require the external reference in order to exist.
