Roger Penrose and Stuart Hameroff propose that consciousness arises when a gravitational field causes quantum wave functions in microtubules in our neurons to collapse, so-called orchestrated objective reduction. The gravity on the moon is a sixth of that on Earth. So, if the idea were correct, we would have expected to see consciousness changes in lunar astronauts. As far as I am aware, none was observed. Perhaps the Artemis programme could investigate this (20 January, p 32).
