Hello all,
I was just wondering what 'an observer' might be in quantum physics, and any definition I can come up with just doesn't make sense.
I strongly oppose the idea that an observer has to have a conscious. Because in that case, one would have to wonder: what is consciousness? Let's say we observer in the form of image: light triggering the sensors in our eyes and sending a signal to the brain. Note that that would not be observing yet, not until the thoughts have been completely processed, because you are not conscious of it yet. Hence history, in this case, would only exist after someone became conscious of it.
Then I can only wonder if your observations make your reality real until I observe it. If not, that means you guy are all a creation of my imagination.
More seriously, this would only leave one conclusion: our brain is supernatural. If not, then there is no real conscious. It is only chemicals in our brains, that are based on exactly the same physics that don't exist until it is observed.
It just doesn't sound right to me one bit.
Then there's the other thing I can think of, that any interaction with any other particle is an act of observation. For instance, a photon colliding with a particle would be an observer, as would a magnetic field. This sounds a lot more plausible to me and yet it doesn't completely add up to me.
Consider the double slit experiments with electrons. If one observes the electron (in this case, have another particle interact with it) right at the slit, it loses its wave-like property. However, during the entire experiment the electron is "observed" by the gravitons created by earth.
Hence my question: what is an observer exactly?Thanks in advance
