Before watching the animations of Alice Law, I suggest you read the book “Alice Law – Transition to (c+v)(c-v) Mathematics in Electromagnetic Theory. 

This animation shows how Dimension Shift occurs in movements faster than light. However, there is no limit in terms of speed. You can do an analysis for any speed value by changing the speed of the observer. The animation works between 0.5 – 2 speed values. 1 speed value is the speed of light. For movements faster than light, values more than 1 should be used.


We will see the answer to the question “How does an observer see if he goes faster than light?” in more detail. This topic has been covered in the Reverse Image animation, but it is not as detailed as it is here.


The signals that are emitted in the animation carry a color code within themselves. The signals that are sent from the right side of the sun carry the color code Blue and the ones sent from the left side of the sun carry the color code Red. While each signal reaching the observer forms the Image Object with the information they carry within themselves, they also give colors to the Image object with the color code they carry. In this way, we can understand with which signals, coming from the right or the left side of the sun, the parts that belong to the Image Object are formed.

The signals set out the moment we start the animation (Let’s set the speed value to 1.25). However, as the observer moves faster than the speed of light, we can see that the signals that come to the observer shift towards the left side of the sun.  

The signals that come towards the observer travel within the field of the observer and move at “c” speed in this field. The observer carries his own field in the direction of his movement while he is moving. As the observer moves faster than the speed of light, the signals that travel within the field of the observer shift towards the left in the direction of the observer’s movement instead of going towards the observer. 

It is seen that the Image Object starts to form when the observer aligns with the sun. However, we need to be cautious; at this stage, the signals now come to the observer from two different directions: the signals which remained in front of the observer and coming towards him from the front AND the signals that have just been emitted from the sun and are coming from the back. We see that two different images are formed as a result of this: the Reverse Image Object that is formed in front of the observer and the second Image Object formed behind the observer. 

When all the signals coming from in front of the observer reach him, the reverse image object in front of him disappears. The Image Object of the sun that is formed behind him is permanent.

What is the option “Shading Factor” in the animation?
Normally, the physical presence of the Sun needs to prevent some signals from reaching the observer. In the movements faster than light, while the signals carrying the color code blue shift to the left, the mass of the sun should shade on these signals. In the movements slower than the speed of light, on the other hand, the Sun should shade on signals carrying the color code red. When “Shading Factor” is activated in the animation, the signals that are exposed to the sun’s shading become ineffective. Image Object is only formed by the signals that are not exposed to shading. Such a modelling is more compatible with the realities of the nature. For the observer, there is no difference in terms of the Image Object that he sees between two situations. I would like to remind you that we are watching the animation from the side. The observer, however, watches it from the front and the back. 

By changing the observer’s position on the Y axis and his speed, you can analyze different situations. The behavior of the signals and the Image Object formed is worth seeing in every aspect.
