Although time travel remains the biggest dream of many of us, we have not yet achieved much concrete success in this regard. Agree, How is it possible to reverse time? At least in linear time first success was achieved.

Scientists are ‘into electromagnetic signals’temporary reflection‘ could be observed. In other words, the signal traveled backward in linear time as if it were rewinding a movie.

First, let’s see what temporal reflection is:

The reflection you now see in the mirror when we go in front of a mirror is actually ‘spatial reflection‘ and our image is reflected in the opposite direction, time in the mirror continues to flow linearly. Likewise, if you become Rocky and go up the mountain and yell “ADRIAN,” the echo you hear will be “ADRIAN” again.

But with temporary reflection, the situation is quite different. This event, which was put forward 60 years ago and has remained only a hypothesis to this day, causes the time reflection of the ‘ADRIAN’ signal to return as ‘NAIRDA’, to put it simply.

How was this transient reflection observed?

Unlike spatial reflection, temporal reflection does not occur as a result of hitting something. Instead, it is possible due to a sudden change in the characteristics of the environment in which the signal is located. Part of the signal, as we see in the red part in the image above flows from the present to the past.

For the change of scenery that allows for transient reflection, scientists have “characteristics not found in nature.”from metamaterialstook advantage.

What is ‘Metamaterial’?

Microscopic structures made with materials such as metamaterials, plastic and metal, like repeating patterns made by combining Thanks to these materials, it is possible to observe the interactions of light and sound that cannot be seen in nature.

Progress of work with metamaterial:

Let’s go back to the same image. The signal we see in blue in the image is the original signal, while the red colors represent the counter-current signals. The green control signal is used to activate the switches on the 6 meter long metamaterial.

With the keys closed resistance change is provided in the environment and thus the requirement of environmental change is met. The blue signal is inverted in linear time, as indicated by the red colors.

What will this historic achievement bring us?

Success will not show us all the time in the world as if it were a reflection. But according to scientists computers of small size, low power consumption and working with signal waves and will pave the way for the development of new ways of wireless communication.
