From Ton Smit, Utrecht, The Netherlands
I can imagine that we humans influence space-time, but not that we create it, as you suggest in your new perspective on quantum reality (5 February, p 38). Who created space-time when humanity didn’t exist?
I always had difficulty with Schrödinger’s cat. For me, it is clear that the cat is either dead or alive. You just don’t know which one it is. I don’t grasp how not knowing something could create space-time realities. When I ask my friend to choose a number between 1 and 10 and he does that, but doesn’t reveal his choice, then I don’t believe that he is in a superposition of 10 states in space-time. I just don’t know his choice. Or are space-time realities only created on a subatomic level?
