Whether light appears to be a particle or a wave depends on how the observer chooses to look at it. With subatomic particles, another particle can be bounced off the particle we wish to observed. The resulting impression may be recorded on a kind of photographic plate . In other words, the act of observation affects the thing observed. There is no objective reality.
Reality is subject to the observer.
If we want to accept reality as it actually is, we must accept that there is no intrinsic division in it. The future is beyond division. Linked notes Readers interested in thinking are referred to any book by Edward de Bono, particularly Lateral Thinking. Decartes and his Cartesian Dualism were major perpetrators here. The observed thing is not intrinsicaly one or the other.
