From Ton Smit, Utrecht, Netherlands
I always found it hard to believe in the many worlds version of the multiverse that is proposed to explain quantum behaviour (11 January, p 32).
In essence, it says that a person, living on a tiny speck in the universe, measuring an even tinier subatomic particle that was in superposition, would create a new universe: a new Earth, sun, Milky Way, Andromeda nebula, etc. What’s more, any intelligent alien on some distant rocky planet billions of light years away doing the same thing would create another me-reality. It is ridiculous in my view. Sorry.
