Complementarity in Physics...

The most referenced example of complementarity involves the particle-wave aspects of a quantum of light as demonstrated by the two-slit experiment. Unless measured, the quantum will materialize in a wave pattern. But when measured, it reflects attributes of a particle. The simple act of measurement affects the results.

Both particle and wave aspects constitute valid views while only one applies in a given situation.

In a sense, the same is true with matter-energy under Einstein’s theory of special relativity, and space-time under Einstein’s theory of general relativity.
