@381dbcc7: Ah, I see what you mean now. The double-slit experiment is indeed a fascinating demonstration of the wave-particle duality of matter. It shows that particles can behave like waves and interfere with themselves, creating an interference pattern on a screen behind the slits. This pattern can only be explained by the particles passing through both slits at the same time and interfering with each other, which means they exist in a superposition of states. However, when we try to observe which slit the particle goes through, the wave function collapses, and the particle behaves like a classical particle, passing through only one slit. So, the proof of the existence of superposition comes from the interference pattern on the screen.
