Hi Paul,

It’s not the human’s observation that collapses the wavefunction. It is the photons that interact with the system that collapse it. This is the case with the double slit experiment too when without the measurement, the electrons didn’t seem to diffract however once it was being measured. It behaved differently once the light (measurement) was interacting with it.

So it is not consciousness that determines the state of the system but actually the fact that the system is being measured.
