Does the Moon disappear when nobody is looking at it?

Does the Moon disappear when nobody is looking? There is a kind of quantum knowing where if not observed, the particle actos like it takes all possible paths open to it.

According to the 2 slit experiment, an electron passes through this device somehow it must know - how many slits are open and how many are closed. Somthing spreads out through the entire apparatus and the conciouness of the reasearchers, to find the status of its parts, and collects information where "reality is created by observation."

 

This is why the Moon disappears when nobody is looking at it, and only re-appears when sombody tries to view it.

The Moon exsisted only in a hyperstate before the first humans viewed its existence, which brings up the question of why the Moon should be there in the first place. Possibly, the Moon was placed there by advanced civilizations to watch Earth and the growth of our planet. - That there may be a some type of Bracewell probe inside the Moon. (similar to the ideas in the movie 2001)

I think this is based on perhaps confusion between "looked at" and "observed". Typically the wave collapse function is associated to being "observed". This does not mean it has to be "looked at" by a human.

 

We can not "look at" a photon. We do have electrochemical reactions when photons enter our eyes. These reactions are transmitted to our brains and our brains create what we interpret as pictorial representations of the results.

 

But we can not "see" a photon as it goes past us.

 

What QM tends to mean when it discusses wave collapse and "observing" is that any time we "test" or "observe" in such a way that we are "expecting" a wave, we get a wave, when expecting a particle we get a particle.
