My thoughts on the physical universe turned toward philosophy and my sci-fi novel, and it brought a new insight that I did not consider before.

What if the dimension of distance and length is not as fundamental as we thought?

All physics have assumed that distance in the 3D universe is fundamental and absolute.

Yet, what if it is not? What if distance is as much of an illusion as many other things? What if distance is an illusion created by some other physical properties, such as time and energy?

For certain, we perceive distance, that much is established, but our perception of distance is dictated by other things which also depend on distance.

Consider, that the General Relativity on speed of light, that it remains constant regardless of the physical time frame which the observer travels in.

However, the energy of the light does change in reference to the time frame. Stars moving away produces light shifted toward Red, whereas stars moving toward you shifts toward blue.

This cannot easily explained, though General Relativity gives mathematical acceptable explanation.

Consider that light quanta is inversely proportional to the square of the Wavelength, a measure in length. And changes in time frame, causes changes in the wavelength of the light, a change in distance.

Perhaps, somehow, Time, energy and distance are related in a different way, that Distance is an illusion.
