B Does a particle have a conscience of its own?

[Debaa]

We know that when many particles are shot through the double slit they make an interference pattern. Also when a single particle passes through double slit it makes an interference pattern, ie one particle passing through two slits at once.

But when we put a particle detector near the slits that beeps when it detects a particle, the particle doesn't make an interference pattern, which means the particle knows that it is being observed? Does a particle have a conscience of its own? If so then how come it can't observe other particles and collapse their wave-function? Thank you for you answer.

Hello and welcome to PF!

The double slit experiment is one of our most asked questions.

No, it doesn't. It hits the detector at a particular single point. The interference pattern forms if you run the single-particle experiment many, many times, one particle at a time.

A single particle doesn't make a pattern. But if you would take a detector behind the slits that detects single particles, and you would slide the detector slowly across the scene while detecting particles, you would see a pattern.
