You cannot observe a photon without some type of apparatus, the apparatus will interact with the photon. quote:
Reality is the state of things as they actually exist, rather than as they may appear or may be thought to be.[1] In a wider definition, reality includes everything that is and has been, whether or not it is observable or comprehensible. A still more broad definition includes everything that has existed, exists, or will exist, not just in the mind, or even more broadly also including what is only in the mind. Wikipedia: Reality Thus, there is a "reality that isn't real", but it exists in reality, only in your head. I usually break it into four basic realities for the sake of clarity: Objective Reality: the state of all energy in the universe (or multiverse, if you like) - our perception of which is strictly limited by time, space, and other perceptual limitations we are heir to, described by: Objective Consensus Reality: a symbolic consensus model of what we currently know or suspect about objective reality, subject to consensus, testing, revision, etc., the scientific method basically. Subjective Reality: an internal model of what an individual imagines reality to be, which often engenders: Subjective Consensus Reality: a consensus model of reality, which is not supported by evidence (though parts of it may be), but by subjective considerations: perceptual errors, political influence, etc. Religions for example, each of which presents a distinctive subjective consensus model of reality, often split into myriad subsets reflecting perceptual, philosophical and political differences.
