Is there any law that prevents us from accurately measuring the momentum of a particle , just like the energy time uncertainty principle makes us observe the system for an infinite amount of time before we can be certain about its energy? I got this doubt because if we can do it, we will collapse the wave function into the eigenstate of momentum, which is not a normalisable state. I know that practically, measurements always come with some uncertainty, but at least in theory can we do it?
