Cosmology: The atom and the point of view of the observer.
To be sighted, the subatomic particles need to be illuminated. The principle of uncertainty attests that this condition disturbs the particle, so that we can only observe it with delay, or out of its true position. Although we have the exact notion of this, we seem to neglect the carrier of information about the particle, the messenger of space represented by light. This is a problem that concerns only the operator of the system, endowed with a memory, because the particles are not concerned with our points of view. However, if we give due importance to radiation and its harmonic motion, we will see that this could even influence the direction of some forces acting in space-time. Good reading! J.R.
