The observer had ability to change the way quantum entity (electron, photon, etc) behave, in the sense that when we were observing it, suddenly we found particle pattern, otherwise we saw interference pattern (wavefunction).
It can be understood that when someone was reporting his observation (and found particle pattern or whatsoever) to us, then we could say that at the same time and at the same placement it was an interference pattern.
- Meaning, at the same time and at the same placement there were two states, it was interference pattern and particle pattern and it was coming from one typical of source which was quantum entity (electron, photon, etc). And there was no distance in between the two states. It was definitely contradiction. Otherwise it’s just a potentiality which can be known differently dependent upon different point of view (by observing it or else).
- I am going to use parable: it’s similar to this, there was Hexadecimal data, or more popular we might say it’s potentiality to be observed as an image file (*.jpeg). While we weren’t observing this Hexadecimal data (having potentiality to be observed as an image file), this Hexadecimal data remained on its own state as Hexadecimal data. But once we were using computer system to look at it, suddenly we could see picture, image of it. We didn’t see Hexadecimal data, but we saw an image. Suddenly, Hexadecimal data was converted (changing) on our perception as (to be considered) solid thing (meaningful) as an image. And this hexadecimal data were created based on binary data.
- This binary, at the same time and at the same placement had two states, it was hexadecimal type of data and image type and it was coming from one typical of source which was binary file. And there was no distance in between the two states. It was definitely contradiction. Otherwise it’s just a potentiality for binary data which can be known differently dependent upon different point of view (by observing it or else).
