o paradoxo do coelho branco
E se o universo se descarrilasse e se tornasse mais quá quá? A Alice e as criações do Lewis Carroll são uma maravilha mas pouco percebo de matemática e física quanto mais quântica; no entanto lêem-se coisas interessantes por palavras, como este paradoxo do coelho branco:
"If all possible universes exist, then what is to say that our orderly, well-behaved universe won't suddenly start to behave in a disordered fashion, such that most inductive predictions would fail in them. This problem has also been called the White Rabbit paradox, presumably in a literary reference to Lewis Carrol.
This sort of issue is addressed by consideration of measure. We should not worry about the universe running off the rails, provided it is extremely unlikely to do so. Note that Leslie uses the term range to mean what we mean by measure. At first consideration, it would appear that there are vastly more ways for a universe to act strangely, than for it to stay on the straight and narrow, hence the paradox. (...)"
Excesso de realidade também leva a irrealidade, fica bem aqui dizer. Mas melhor será não repetir de novo o que é essa coisa da r...(pode-se contradizer um paradoxo?)
