A common perception we all have about the time machine is that it is a special vehicle of modern information technology that can take us to the future and the past. By traveling in a time machine we can do everything in the future and in the past as in the present. Scientifically the time machine is conceptualized in such a way that no change in our own position will be made by the time machine. Only the environment will change. When traveling in a time machine we will be in the same place we were but the location and time of everything around us will be completely changed. Once we naturally think that we have reached the future. Then we go into the future and see that the world may have advanced one or two hundred years. Then everything will seem strange and new things will be seen to us. New technology things may surprise us everywhere. A whole new world will come to us. Then we can look at our own body and see that we are the same as before. We are not old and no physical aging occurred. But everything in the rest of the world has changed. The world has moved on one or two hundred years. Now the most surprising thing is why we will not change while everything in the whole world will change. Another thing we will notice as we go into the future is that we have landed in the time machine from where we got up in the past. That means there is no change in our position and place. But the surrounding things have all changed. In the future we will see more and more advanced technologies. Then we will feel very fool and old fashioned. The opposite of all this would happen if we went into the past in a time machine. ‌Behind if we use a time machine for go back one or two hundred years before the present. Then let's go and see where the world is more backward. There is no touch of modern technology. Even there our age will remain the same. Also we will not have any physical aging. Instead we will feel more sophisticated. The way of life of all people in the past was very normal. Then we will feel wiser and more powerful in that situation. Many of us think that if we could see the future we would have acted according to the future. We cannot really change the future. We can't change even the past. The truth is that we cannot go to the past or the future with any time machine on earth. Time travel in a time machine controls time. There are many ways to slow down time. By using any method that can be made time machine. The easiest way to do this is to make the machine spin faster than the speed of light. This simple work is the hardest work in the world. If we can move anything at the speed of light then our dream time machine will become a reality. Then we will become the father of the time machine. On the other hand a fortune telling machine and a time machine are not the same thing. Many claim that fortune telling machines act as time machines. In fact there is no such thing in a real time machine. The working of the real time machine is very different from the simple time machines. We have seen in various movies. In fact the way the time machine works are different from the real time machine and movies time machine. If we sit in the invented time machine to travel to the past or the future and start the machine. This machine will start rotating at the speed of light. Then this rotation will cause the local time inside the machine to completely slow down. Consequently if we spend a minute or a day inside the machine then it may be a year outside the machine. That is time travel. In fact if we think naturally we can see that the time machine is set in our brain. We never felt it. But if we observe well then we can understand the matter. The real explanation and real evidence is that this time machine works when we are deep in sleep and in a dream. We can often see many things in the future in our dreams. It turns out that after a few days the thing that we saw in the dream happened to us. It also happens that we have gone to the past in the dream. Later when we come back to the normal state from the dream. Then we woke up. Then we find that we are still where we were. Our position and body itself did not change but everything around us changed. In reality we travel through the natural time machine in our sleep and dreams. But we cannot change our future or past. This will not be possible in future. In fact we can never change our future nor can we change our past. By going into the future and past it is never possible. This is the secret of creation. Nowadays using modern information technology we get a lot of information in advance of natural disasters. By analyzing this information we can make some preparations. But we cannot change anything before or after the moment of disaster. Finally this is eternal truth. We travel a long way in a short period of time in our dreams. After breaking the dream again we quickly left that place in a short time. In less than a few thousand times a second we travel to the future and the past with the help of natural time machines and return to a specific place. With the touch of modern information technology we may discover the time machine. But by this we cannot change our past and future. We all sometimes wish we could know what will happen in the future or go back in time and correct some act or mistake. On the other hand if we could go back to the past we would be able to correct the mistakes of the past and live the latest life we want now. By this general concept the first thing that comes to mind from this thought is the time machine. Scientist Isaac Newton believed that time flows at the same rate everywhere in the universe. So according to this calculation one hour passing on earth means one hour passing everywhere in the universe. That is what has happened is the past for everyone. On the other hand the scientist Einstein contradicted this and said that the rate of time flow is not the same in all places of the universe. What happened may not be the past for everyone. In this regard after the publication of his theory of relativity everyone's perception of time changed radically. If a person is put in a spaceship that can travel at the speed of light and he travels across the universe and comes back to earth. But after returning to earth many years will appear to have passed where to that person it would seem that only a short time has passed. This is how the time travel formula is explained in Einstein's theory. In a practical sense if somehow we could travel at the speed of light at 186,000 miles per second time travel in space would be possible. The faster an object is moving the more constant time is relative to it. The speed of light is about 186,000 miles per second. And humans can travel as fast as 7 miles per second in rockets so far. It is not faster than the speed of light. It is a long way to get closer to reach the speed of light.
