How to solve Schrödinger's Cat paradox: Can a cat be dead and alive at the same time? No, it can't. Here is why 🧵
1
The paradox assumes that a decaying radioactive element is in superposition and that the superposition extends to the whole box including the cat, finally placing the cat in a dead and alive state.
2
However, what would prevent the cat from being in a superposition of two contrary states (dead and alive) is decoherence.
3
Interaction with the environment like the Giger counter would collapse the wavefunction (measurement) and nature would commit to a more concrete state. Paradox solved.
