15. BYTE SHIFT
Byte Shift is an effect on the communication signal as a result of wavelength change during the communication between reference systems that are in motion relative to each other. It is not a recognized topic because (c+v) (c-v) mathematics is not in physics yet; however, its existence is certain. I especially wanted to give priority to Byte Shift since it is quite an informative topic and it gives a great deal of information as it can be covered by using real values.
Let’s have a look at how electromagnetic communication is carried out first.
Delivery of messages takes place in this way: A message is, in its essence, a non-stop chain consisting of 0s and 1s. The transmitter turns each ring of the chain into electromagnetic signals and sends them in order. The receiver perceives the electromagnetic signal coming to itself and again turns it into 0s and 1s according to the order of their arrival and gets the message. Each wave component belonging to the signal (the part equal to wavelength) forms a single ring of the chain that includes the data and carried a data of 1 Bit. The data of 1 Bit consists of value 0 or 1. In order to express an alphabetic character, 8 Bits are needed. The piece of data composed of 8 bits aligned side by side is called Byte.
Below we see how the sentence “HELLO WORD” is written in Bits and Bytes.
In order to make the topic easier to understand, I am going to use a transmitter emitting signals in the shape of a sinusoid as a base. The distance between the signal’s two positive peak points or negative peak points gives us the wavelength of the signal.
As the transmitter sends the message signal chain consisting of Bits in order, from the first to the last one, the state in which the signal is in the sky is in reserve order just like the image on the mirror. I wanted to touch upon this detail while covering the topic in order to reflect the truth as it is.
The wavelength change of the signals sent towards targets in motion lead to changes of the length of signal message released to the sky.
The figure above is drawn relative to the reference system of the transmitter. The transmitter emits the message “Hello World”. The message “Hello World” has 11 alphabetic characters, so it is made up of 11 Bytes and 8x11=88 Bits. The moment the last part of the message, namely the 88th Bit, is emitted is represented in the figure. Because the wavelength of the signals going towards the planes changes and they travel at different speeds, we see that the length of each message going to the receiver in the sky is different.
Grouping of electromagnetic waves carrying the message
I wouldn’t want you to be confused. For this reason, let’s elaborate on the topic even though it might mean repetition. Let’s think about the moment when a single bit sets out from the transmitter. At the moment the transmitter sends the 1 Bit information, it emits almost an unlimited number of electromagnetic waves. While the target of some of these electromagnetic waves is the plane moving away from them, some others’ target is the station on the mountain, and others target the plane approaching. The same things happen the next time the transmitter sends the next data. Therefore, electromagnetic waves that travel at the same wavelength, at the same speed and to the same target form groups amongst themselves. The figure above represents three different groups according to their targets although they carry the same message: group c+v, group c, and group c-v. Message length of one group is determined by wavelength change at the time of the signal emission and it never changes again.
On the top left corner in the figure, we can see that the distance of message groups from the transmitter at the moment of the emission of the last Bit of the message of “Hello World” is zero. As the groups travel on their own paths, because the speeds of the groups are different from each other, they are gradually separated and they move away from each other. Because the fastest group is c+v, it will get ahead of the others and c-v group will fall behind as it is the slowest group. The further the targets of the groups, the more time they will need to reach, which will, in turn, increase the amount of separation.
Duration of receiving of the message
In the figure below, the moment the signals reach their target is represented. The fact that message lengths differ makes the duration of receiving of the message for all three reference systems different.
Duration of receiving of the message = message length / the speed of light constant
Therefore, while the plane coming towards the signal station gets the message in the shortest duration, the plane moving away from the signal station gets the message in the longest duration.
