According to physics science,impossible is nothing.
Films and science fiction novels with the theme of time travel (using various forms of machine time)more popular along with the rapid development of the science of physics.Whether such films Star Trek, Time Machine, Back to the Future,only symbolizes the great imagination of the filmmakers?
Or actual novels and the films of this kind already started to move from the category of science fiction into a new breakthrough of modern technology actually exist in real life? The physicists did not want to miss analyze the scientific aspects of the technologies featured in filmfilm that successfully made it a big advantage. Once the physicists who dared to raise the topic time travel is too busy fantasizing. But physicists now been frantically looking for evidence that could show with certainty that exciting journey through time is not might be done! Concepts of physics are actually supporting this theory.Who would have thought that in fact we are already often traveling through time in our daily lives! And without using a time machine! The road to open this fantastic phenomenon by the famous physicist, Albert Einstein, the theory of relativity.
To understand the concept of time travel, we have first understand the meaning of time (Time). In physics, timeis one of the principal amount which represents the period or interval which can be measured with certainty (international unit is second). We know that a day consists of 24 hours, 1 hour 60 minutes, and 1 minute 60 seconds. 1 second defined as the number of oscillations of cesium-133 atom (9,192,631,770 oscillations)on the atomic clock. With the constants involved, we certainly immediately conclude that the time has an absolute value (exact) and not is the magnitude of its value relative to a particular reference. But Einstein changed this view as the theory of relativity. According to Einstein, the greater the velocity of an object or a particle, when it runs more slowly for objects or particles. When the speed near the speed of light, time is running very slow. What if there is objects or particles moving at speeds exceeding the speed light? Time will run so slow that a moving object with speeds as high as it can go back to the starting position very quickly. So fast, it was back in its initial position before it started moving! This means it has to travel through time into his own past!
