Main Question or Discussion Point
Im just starting to try to break into and understand quantum physics and so this question may be a completely absurd but im curious as to whether or not its been proven that a particle really does act like a wave until observed or if the "spin" of two entangled atoms actually changes opposite of its counterpart or if both of these things can be chalked up to insufficient tools and calculations. Its my understanding that Einstein believed that if we could measure things infinitely better and take into account every factor that probability would cease to exist. Does the WF actually collapse because of the observer or does the WF even exist? Do entangled particles really "snap" to attention when we look at their position, or was the position always as such?
