The observer

We understand everything as observer – abstract- created by our imagination to visualize all events in a reference frame. Therefore, he does not need to be a real person due to he could move in time and space observing everything with an instantaneous vision. As such observer is imaginary, so he is not limited by climatic conditions. Thus, we can imagine him:

On the sun’s surface.

Seated on a photon that is at light’s speed.

In the atom seeing an electron’s orbit.
